Explanation:

Decomposers are especially important in retaining nutrients in their cells thus preventing loss of those nutrients from the root zone.

In an ecosystem, the decomposing web is important because decomposers help remove waste and use that energy to provide food for other animals.

An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass  which is present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Reflecting telescopes are preferred for scientific research because they are better suited for gathering large amounts of light and producing high-quality images. However, refracting telescopes are still popular for amateur astronomers and for viewing objects on Earth.

Reflecting telescopes are different from refracting telescopes because reflecting telescopes use mirrors, whereas refracting telescopes use lenses. The reflecting telescope was invented in 1668 by Sir Isaac Newton, and it has since become one of the most popular types of telescopes.
Reflecting telescopes use a mirror to gather and focus light, while refracting telescopes use a lens to do the same thing. Reflecting telescopes can be made much larger than refracting telescopes because it is easier to make large mirrors than it is to make large lenses. The mirror in a reflecting telescope is placed at the back of the telescope, and it gathers and reflects light back to a secondary mirror, which then reflects the light to the eyepiece. The eyepiece is where the observer looks through the telescope.In contrast, the lens in a refracting telescope is placed at the front of the telescope, and it gathers and bends light as it passes through. The lens focuses the light onto an eyepiece at the back of the telescope. Refracting telescopes are generally smaller than reflecting telescopes because of the difficulty of making large lenses.
Another difference between reflecting and refracting telescopes is the way they are constructed. Reflecting telescopes have a simple tube that houses the mirrors and eyepiece, while refracting telescopes have a more complex design with a long tube that contains the lens and eyepiece.

A. We are aware that the reaction's rate depends on the slowest, or rate-determining, step in the overall reaction mechanism. The first step of the reaction is the one that moves the most slowly in the example reaction mechanism. As a result, just one step (Step 1) would have an impact on the reaction's rate.

As a result, the rate law for the mechanism described is given by –

Step 1.  Cl2 2Cl  (slow)  ---------k1

Step 2.  Cl + C5H10HCl + C5H9  (fast) ---------k2

Step 2.  C5H9 + Cl C5H9Cl  (fast)  ---------k3

Step 1. is the slowest step. So, the reaction rate will depend upon on the rate of Step 1 only.

Hence, the rate law for the reaction is given by –

Rate = k1 [Cl2]

B. A species that is created and then consumed in situation is referred to as an intermediate of a reaction mechanism; hence, reaction intermediates never appear in the final rate law or in the actual reaction itself. The overall reaction in this reaction will show up, and likewise will be included in the rate law, as demonstrated above.

Explanation:

This is 100% Correct

Answer:

The particle theory is the belief that everything in our solar system and beyond is made of very small matter called atoms. The 10 mL is a matter in our solar system and even though we cannot see, there are millions- if not billions of smaller particles that make up the liquid. If you view the picture below, you can see that the particles in a liquid are close to one another, particles in a gas are far apart, and a particle in a solid is tightly pushed together. This gives them their distinctive shape. Since this is a liquid, this means that the particles are close together, but not very close. The particles glide over one another. If you want to have more space between the particles and expand the size of the liquid you can boil the water, however boiling the water turns it into gas and causing the liquid to evaporate. Freezing the liquid would cause the particles to be closer packed together, making a solid. The amount of liquid you have can not change. There is still 10 mL even when the liquid is frozen or when the liquid boils into vapor in the air. Therefore using particle theory, we can know that a shape can only expand or shrink when changing states of matter.

When the child sits on the partially filled balloon, the pressure of the balloon increases. The pressure change is a doubling of the initial pressure, indicating a factor of 2 increase.

When the child sits on a partially filled balloon, the volume of the balloon decreases by half. According to Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume at constant temperature, the pressure inside the balloon increases.

Let's consider the initial volume of the balloon as V and the initial pressure as P. When the volume decreases by half, it becomes V/2. Since the amount of gas remains constant, the pressure increases to maintain equilibrium. The new pressure can be denoted as P'.

According to Boyle's Law, P₁V₁ = P₂V₂, where P₁ and V₁ are the initial pressure and volume, and P₂ and V₂ are the final pressure and volume. Plugging in the values, we have P * V = P' * (V/2).

Simplifying the equation, we get P' = 2P. This means the pressure of the balloon increases by a factor of 2, or it doubles. So, the pressure change can be expressed as an increase of two times the original pressure.

The salt that produces a basic solution in water is NaF.

When a salt dissolves in water, it can either produce an acidic, basic, or neutral solution, depending on the nature of the salt. Salts that are derived from strong bases and weak acids are basic solution, while salts that are derived from weak bases and strong acids are acidic in nature. Salts that are derived from either strong bases and strong acids or weak bases and weak acids are neutral in nature.

In this case, NaF is derived from the strong base NaOH and the weak acid HF, so it is a basic solution. KCl is derived from the strong base KOH and the strong acid HCl, so it is neutral in nature. NH4Cl is derived from the weak base NH3 and the strong acid HCl, so it is acidic in nature. Therefore, the salt that produces a basic solution in water is NaF.

A catalyst increases the rate of reaction but is not consumed by the reaction. Catalysts lower the Positive catalyst energy.

A catalyst is a substance that expedites a chemical process without being consumed by it; as a result, a catalyst can be chemically recovered unaltered at the conclusion of the reaction it has been used to catalyze.

With reduced activation energy and a distinct transition state, catalysts enable an alternative method for the reactants to become products. A catalyst might lower the reaction temperature, speed up the process, or improve the reaction's selectivity. Frequently, when reactants and catalysts combine, intermediates are created that ultimately produce the same reaction products and allow the catalyst to be renewed. The catalyst may be used up during one of the intermediate processes, but it will be regenerated before the reaction is finished.

Answer:

Explanation:

To determine whether there is enough reactant to completely react with the other, we need to calculate the number of moles of each substance and compare them based on their stoichiometric ratio in the balanced chemical equation. The balanced chemical equation for the reaction between calcium chloride (CaCl2) and sodium carbonate (Na2CO3) is,CaCl2 + Na2CO3 → CaCO3 + 2 NaCl

From the equation, we can see that 1 mole of CaCl2 reacts with 1 mole of Na2CO3. Therefore, we need to calculate the number of moles of each substance and compare them. Number of moles of CaCl2 moles of CaCl2 = (0.300 mol/L) x (0.0300 L) = 0.00900 mol Number of moles of Na2CO3 moles of Na2CO3 = (0.800 g) / (106.0 g/mol) = 0.00755 mol Since the stoichiometric ratio of CaCl2 to Na2CO3 is 1:1, we can see that there is less CaCl2 than Na2CO3 in the solution. Therefore, the CaCl2 will be the limiting reactant and there will be some excess Na2CO3 remaining after the reaction is complete. To determine the amount of excess Na2CO3, we can use the number of moles of Na2CO3 calculated above and subtract it from the theoretical amount of Na2CO3 that would react with all of the CaCl2, moles of Na2CO3 reacted = 0.00900 mol moles of Na2CO3 excess = 0.00900 mol - 0.00755 mol = 0.00145 mol The mass of the excess Na2CO3 can be calculated by multiplying the number of moles by the molar mass, the mass of Na2CO3 excess = 0.00145 mol x 106.0 g/mol = 0.154 g Therefore, there will be approximately 0.154 g of excess Na2CO3 remaining after the reaction is complete.

if 30.0 ml of 0.300 m cacl2 are added to an aqeous solution having .800g of sodium carbonante will this be enough reactant. In order to precipitate all of the carbonate ions from an aqueous solution of sodium carbonate, the calcium chloride solution that is added must be the excess reactant.

Answer:

partial pressure of gas D Pd = 15.5 kPa

Explanation:

As per the Dalton's law of partial pressure, in a mixture, pressure exerted by each gas when summed gives the total partial pressure exerted by mixture.

P(Total) = P1+P2+P3.....

Given P(Total) = 35.7 kPa

Partial pressure of gas A Pa = 7.8 kPa

Partial pressure of gas B Pb = 3.7 kPa

Partial pressure of gas C Pc =  8.7 kPa

There, Partial pressure of gas D Pd = P(Total) -(Pa+Pb+Pc)

Pd = 35.7-(7.8+3.7+8.7) = 35.7-20.2 kPa = 15.5 kPa

Therefore, partial pressure of gas D Pd = 15.5 kPa

A hydrogen atom is an atom belonging to the element hydrogen in chemistry. One positively charged proton and one negatively charged electron are both present in the electrically neutral atom and are held to the nucleus by the Coulomb force. Normal circumstances are infrequent for lone neutral hydrogen atoms. Hydrogen atoms can also exist in cationic and anionic states, however neutral hydrogen is frequently seen when it is covalently joined to another atom.

Energy is the quantifiable attribute that is transferred to a body or a physical system in physics. It is observable in the production of work as well as in the form of heat and light. The law of conservation of energy asserts that although energy can be changed in form, it cannot be created or destroyed. Energy is a conserved quantity.

There's an experiment that you can try to see if carbon dixide is heavier than air.

Explanation:

At room temperature, carbon dioxide has higher density (ρ = 1.98 kg·m -3) than air (ρ = 1.29 kg·m -3). The density of gas, however, significantly depends on its temperature. Carbon dioxide produced by burning has higher temperature than the surrounding air.

Why is CO2 heavier than the air?

Short answer is CO2 is heavier than ambient air, but it does not drift to the ground as there is a lot of mixing going on in ambient air. ... Carbon dioxide, also known by the chemical formula CO2, has a higher density than the other gases found in air, which makes CO2 heavier than the air.
