Ideal gas law:
If 6.3 moles of a gas in a 20 L cylinder have a pressure of 5.5 atm, what is the temperature?

The quantity of this pattern whilst the temperature is modified to one hundred fifty. K and the pressure are changed to 160. Kilopascals is 52.5 mL.

The calculation is as follows:

\(\frac{240kPa \times 70 mL}{300K} = \frac{160kPa\timesV2}{150K}\\\\ V2 = \frac{150K}{1600KPa} \times \frac{240kPa \times 70 mL}{300K}\)

So, the Volume is 52.5 mL.

Temperature is measured with a thermometer. Temperature is essential in all fields of natural science, which includes physics, chemistry, Earth technology, astronomy, remedy, biology, ecology, material technology, metallurgy, mechanical engineering, and geography in addition to maximum elements of day-by-day lifestyles.

Thermometers are calibrated in diverse temperature scales that traditionally have depended on various reference factors and thermometric materials for definition. The most not unusual scales are the Celsius scale with the unit image °C (previously called centigrade), the Fahrenheit scale (°F), and the Kelvin scale (ok), the latter getting used predominantly for medical purposes.

The emigration of wolves from a grassland ecosystem that supports rabbits which happens to be wolve's primary prey will lead to an increase in the population of rabbits in the ecosystem

Predators and preys share a relationship such that the former feeds on the latter as food. Thus, the presence of wolves serves as a limiting factor to the growth of the rabbit population.

Therefore, once the wolves emigrate away from the ecosystem, the population of rabbits will thrive because one of its limiting factors has been removed.

The ratio of the actual yield to the theoretical yield, presented as a percentage, is called the percent yield.The percent yield of CO when 20.0g O_{2} is used is approximately 342.86%.

In this chemical reaction, the balanced chemical equation is:C(g) + O_{2}(g) → CO(g)The amount of O_{2} used in the reaction is given as 20.0g. The actual yield of CO is given as 60.0g. We are supposed to find out the percent yield of CO.To calculate the percent yield, we can use the formula:percent yield = (\frac{actual yield }{ theoretical yield}) *100 here, the theoretical yield of CO can be calculated by using the stoichiometry of the reaction. The stoichiometric ratio between O_{2} and CO in the balanced equation is 1:1.Therefore, the number of moles of O_{2} used in the reaction is the same as the number of moles of CO produced.

From the given mass of O_{2} (20.0g), we can calculate the number of moles of O_{2} as follows:mass of O_{2} = 20.0g

Molar mass of O_{2} = 32.00 g/mol: number of moles of O2 = \frac{mass }{ molar mass}= \frac{20.0 g}{ 32.00 g/mol}= 0.625 mol

According to the balanced equation, the same number of moles of CO will be produced as that of O_{2}. Therefore, the number of moles of CO produced is:0.625 mol

To calculate the theoretical yield of CO, we can use the molar mass of CO as follows: Molar mass of CO = 28.01 g/mol

theoretical yield of CO = number of moles * molar mass= 0.625 mol *28.01 g/mol= 17.50 g

Therefore, the percent yield of CO is:percent yield = (\frac{actual yield }{ theoretical yield}) *100= (\frac{60.0g }{17.50g}) * 100= 342.86% (approx.)

Therefore, the percent yield of CO when 20.0g O_{2} is used is approximately 342.86%.

Answer:

In your science class, you will learn about Newton’s laws of motion. Do you know why these laws are so important? When you throw a baseball or you bounce a basketball on the court, you can use Newton’s laws to explain the motion of the baseball or basketball. In fact, almost all motion in the world can be explained by these laws. Newton’s laws are useful when people design airplanes, trains, cars, sports equipment, toys, and many things that have to do with motion. Some people have trouble understanding Newton’s laws of motion because it’s hard to see how the laws work without any examples. One great way to understand these laws is to look at how they relate to cars in everyday life.

The First Law of Motion

“Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it.”

Can you see why it’s hard for some people to understand the first law? Those are some complicated words. To help you to understand better, let’s break it down and use the example of a car. The first part deals with an object in a “state of rest”. This means that the object is not moving. When your mom or dad parks the car in the garage or the shopping mall, the car is said to be in a “state of rest” because it is not moving. The car will not move until the engine is started and somebody drives it away. The second part deals with an object in “uniform motion”. This means that the object is moving at the same speed. When you mom or dad is using “cruise control” on a highway at 60 miles per hour, the car will be moving at that speed in a “straight line” until something happens to change it. What is this change? It depends. By using the brakes, your mom or dad can slow the car down or bring it to a stop. On the other hand, the car’s direction will be changed if it is hit by another motor vehicle.Explanation:

When a Lewis acid and a Lewis base combine, the product may be referred to as an adduct.

An adduct is a chemical species that is formed when a Lewis acid and a Lewis base combine through a coordinate covalent bond. In this reaction, the Lewis base donates a pair of electrons to the Lewis acid, which accepts the electrons. This results in the formation of a new molecule, called an adduct, which contains a new covalent bond.

An example of an adduct is the reaction between boron trifluoride (BF3) and ammonia (NH3) to form boron trifluoride ammonia complex (BF3•NH3), which is an adduct.

199.86 0r 200g/mol molar mass for the compound cabr2

The orbitals or shells that enclose an atom's nucleus are home to electrons. In the nucleus, protons and neutrons are present. In the atom's nucleus, they coalesce. An atom's nucleus is surrounded by electrons in distinct orbits. The molar mass is calculated by dividing the mass (g) of a certain chemical element or chemical compound by the amount of the substance (mol). The standard atomic masses (in g/mol) of the component atoms can be added to determine the molar mass of a compound.

Thus, the molar mass of CaBr2 can be calculated as shown below.

Molar mass=(1×40.078gmol+(2×79.904gmol)

=40.078gmol+159.808gmol

=199.886gmol

Hence, the molar mass of CaBr2 is 199.886gmol.

Increasing [Ag+] should be done in the following order: Solution X, Solution Y, and Solution Z. saturated solution.

What is saturated solution?

A saturated solution is one in which, at a specific temperature and pressure, the maximum amount of solute has been dissolved. In other words, under those circumstances, no additional solute can be dissolved in the solvent.

.We must evaluate the solubility of silver compounds in each saturated solution in order to establish the sequence of increasing [Ag+] (silver ion concentration) for the solutions X, Y, and Z.

AgCl, followed by AgBr and AgI, has the lowest solubility product constant (Ksp) value, as can be seen from the table. The solubility of the molecule and the concentration of the corresponding ions in the solution decrease with decreasing Ksp values.

Based on this knowledge, we can arrange the answers in the following sequence, increasing [Ag+]:

Solution Z: AgI will produce the highest [Ag+] concentration since it is the most soluble of the three silver compounds.

Solution Y: Because AgBr is less soluble than AgI, Solution Y will have a lower [Ag+] concentration than Solution Z but a greater concentration than Solution X.

The lowest [Ag+] concentration among the solutions may be found in Solution X, which contains AgCl, which is the least soluble of the three silver compounds.

Therefore, increasing [Ag+] should be done in the following order: Solution X, Solution Y, and Solution Z.

Answer:

0.125L or 125 mL

Explanation:

0.125L of 3.00M KI stock solution is required to make 0.300 L of a 1.25M KI solution.

A solution is a homogeneous mixture of one or more solutes dissolved in a solvent.

A stock solution is a concentrated solution that will be diluted to a solution of lower concentration.

stock solution = diluted solution

Where, M1 = concentration in molarity (moles/Litres) of the   concentrated solution

V2 = volume of the concentrated solution,

M2 = concentration in molarity of the dilute solution

V2 = volume of the dilute solution.                                

The volume of 3.00M KI solution can be calculated using the dilution equation:

Given:

M1 = 3.00M, M2 = 1.25M, V1 = x, V2 = 0.300L

M1V1 = M2V2

3.00M(x) = 1.25M(0.300L)

           x = 0.125L

Hence, 0.125L of 3.00M KI stock solution is required to make 0.300 L of a 1.25M KI solution.
