To make a 50.0 mL solution of 1.7 M sodium carbonate (Na₂CO3), we need to determine the mass of Na₂CO3 required.

To calculate the mass of Na₂CO3 needed, we can use the formula:

Mass = Concentration x Volume x Molar Mass

First, we convert the given volume from milliliters to liters:

Volume = 50.0 mL = 50.0/1000 L = 0.05 L

Next, we substitute the given concentration and volume values into the formula:

Mass = 1.7 M x 0.05 L x Molar Mass of Na₂CO3

The molar mass of Na₂CO3 can be calculated by adding the atomic masses of sodium (Na), carbon (C), and three oxygen (O) atoms:

Molar Mass of Na₂CO3 = (2 x Atomic Mass of Na) + Atomic Mass of C + (3 x Atomic Mass of O)

After obtaining the molar mass value, we can substitute it into the formula and perform the calculation to determine the mass of Na₂CO3 required to make the 50.0 mL solution of 1.7 M sodium carbonate.

Heat is a form of energy that gives the sensation of warmth to us.

Explanation:

Answer:

We have nerves that are just like wires that run through our body that tells us what is going on and what to do about it. The hard dive like in a computer is our brain, which is made up of three parts that control things like coordination, movement, involuntary, and voluntary movement. The sensory numerous just like the keys in a computer pick up what we are doing in life.

Explanation:

For the first unknown concentration with an absorbance of 1.72, the concentration will be, c = 1.72/(ɛ × b). For the second unknown concentration with an absorbance of 0.75, the concentration will be: c = 0.75/(ɛ × b).

Beer lambert's law states that the concentration of a solution is directly proportional to the absorbance of a solution. Mathematically, Beer's Law: A = εlc

where, A is absorbance, ε is the molar absorptivity, l is the path length, and c is the concentration.

We can rewrite the equation as, c = A / εl

where, c is the concentration, A is the absorbance, ε is the molar absorptivity, and l is the path length.

We have two absorbance values, which we will use to determine the concentration of the unknowns. Let's substitute the given values into the equation to determine the concentration of the first unknown.

where, c₁ = A₁ / εlc₁ = 1.72 / εl (1)

Now, let's substitute the second absorbance value to determine the concentration of the second unknown.

c₂ = A₂ / εlc₂ = 0.75 / εl(2)

The concentrations of the unknowns are c₁ and c₂, which we have expressed in terms of the concentration of the solution. The total concentration of the solution is not provided. Thus, we cannot determine the concentration of the unknown solutions.

Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud. When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two charges within the cloud.

Explanation:

Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud.

In electricity generation, a generator is a device that converts motive power (mechanical energy) into electric power for use in an external circuit.

Lightning is an electric current. To make this electric current, a cloud is needed.

When the ground is hot, it heats the air above it. This warm air rises. As the air rises, water vapour cools and forms a cloud. When air continues to rise, the cloud gets bigger and bigger. In the tops of the clouds, the temperature is below freezing and the water vapour turns into ice.

Now, the cloud becomes a thundercloud. Lots of small bits of ice bump into each other as they move around. All these collisions cause a build-up of electrical charge.

Eventually, the whole cloud fills up with electrical charges. Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud.

When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two charges within the cloud. This is like a static electricity sparks you see, but much bigger.

Hence, the positive and negative charges grow large enough, that a giant spark - lightning - occurs between the two charges within the cloud.

If 120 cm³ of oxygen gas is collected at 713.3 mm Hg pressure, the volume of the dry gas at STP is 0.102 cm³.

To solve this problem, we will use the ideal gas law, which relates the pressure, volume, temperature, and number of moles of a gas:

PV = nRT

First, we need to convert the given conditions to the correct units. The temperature is already in Celsius, so we need to convert it to kelvins by adding 273.15:

T = 27 + 273.15 = 300.15 K

The pressure is given in millimeters of mercury (mm Hg), so we need to convert it to atmospheres (atm) to use in the ideal gas law. There are 760 mm Hg in 1 atm, so:

P = 713.3 mm Hg / 760 mm Hg/atm = 0.938 atm

Next, we can use the ideal gas law to find the number of moles of oxygen gas:

n = PV/RT = (0.938 atm)(120 cm³)/(0.08206 L·atm/(mol·K))(300.15 K) = 0.00454 mol

Finally, we can use the molar volume of a gas at STP (standard temperature and pressure) to find the volume of the dry gas at STP. At STP, the temperature is 273.15 K and the pressure is 1 atm. The molar volume of a gas at STP is 22.4 L/mol, so:

V = n(22.4 L/mol) = (0.00454 mol)(22.4 L/mol) = 0.102 cm³

Therefore, the volume of the dry gas at STP is 0.102 cm³.

Peroxides species shows the correct charge of the oxide ion.

As predicted by the two partially filled outer orbitals, oxygen assumes a negative oxidation state in all of its molecules. The oxide ion O2 is produced when electron transport fills these orbitals. It is thought that each oxygen in peroxides (species that contain the ion O2 2) has a charge of 1.

The carbon and hydrogen atoms have a slight positive charge, while the oxygen atom has a slight negative charge.

There are six valence electrons in the atom of oxygen. The oxygen atom requires two additional electrons in order to complete its valence shell. Adding two more electrons gives the oxygen ion a charge of two because each electron has a single negative charge.

To determine the variable cost per minute for a company's phone bill, you would need to first calculate the total phone bill for the period in question and then subtract the fixed costs from that amount. The resulting amount would represent the total variable costs. To find the variable cost per minute, you would then divide that total by the total number of minutes used during the same period. This calculation would give you the average variable cost per minute for the company's phone usage.

Variable costs are costs that change in proportion to the business activities of the company or individual. Variable cost is the sum of the marginal costs over all units produced. This can also be considered a normal fee. Fixed costs and variable costs form the two components of the total cost. It is important to understand this so that you can discover the core concept or logic of variable costs to solve for a company's variable average.

A carbohydrate is formed from carbon, hydrogen and oxygen. These three elements are combined in every carbohydrate.

Even though carbohydrates are composed of only these three atoms, the number of atoms of these elements in each carbohydrate as well as the spatial arrangement of these atoms in each carbohydrate is not the same.

This means that different carbohydrates contain different number of carbon, oxygen and hydrogen atoms which are arranged in different ways in space. This gives room for the existence of many different types of carbohydrates all consisting of carbon, hydrogen and oxygen atoms.

The information regarding the different carbohydrates that should be formed is explained below.

It should be created from carbon, hydrogen, and oxygen. It should be combined with every carbohydrate. Still, carbohydrates should be comprised of only these three atoms, so the no of atoms of these elements in every carbohydrate also the spatial arrangement of these atoms in every carbohydrate is not similar.

Answer: 1. Two protons within the Sun fuse. Most of the time the pair breaks apart again, but sometimes one of the protons transforms into 2.a neutron via a weak nuclear force. Along with the transformation into a neutron, a positron, and neutrino are formed. This resulting proton-neutron pair that forms sometimes is known as deuterium.

3. A third proton collides with the formed deuterium. This collision results in the formation of a helium-3 nucleus and a gamma ray. These gamma rays work their way out from the core of the Sun and are released as sunlight.

4Two helium-3 nuclei collide, creating a helium-4 nucleus plus two extra protons that escape as two hydrogens. Technically, beryllium-6 nuclei form first but are unstable and thus disintegrate into the helium-4 nucleus.

Explanation:

The final helium-4 atom has less mass than the original 4 protons that came together (see E=mc2). Because of this, their combination results in an excess of energy being released in the form of heat and light that exits the Sun, given by the mass-energy equivalence. To exit the Sun, this energy must travel through many layers to the photosphere before it can emerge into space as sunlight. Since this proton-proton chain happens frequently - 9.2 x 1037 times per second - there is a significant release of energy.[3] Of all of the mass that undergoes this fusion process, only about 0.7% of it is turned into energy. Although this seems like a small amount of mass, this is equal to 4.26 million metric tonnes of matter being converted to energy per second.[3] Using the mass-energy equivalence, we find that these 4.26 million metric tonnes of matter are equal to about 3.8 x 1026 joules of energy released per second!

At STP, iodine (I2) is a solid crystal and fluorine (F2) is a gas. A sample of I2 at STP is held together by van der Waals forces, which are weaker intermolecular forces. On the other hand, a sample of F2 at STP is held together by much stronger intermolecular forces than I2 due to its smaller size.

Therefore, F2 has stronger intermolecular forces than I2. It can be explained in a long answer as follows:At standard temperature and pressure, iodine (I2) is a solid crystalline substance. Its physical state is a solid because the intermolecular forces that bind the iodine molecules together are weak van der Waals forces. These forces are much weaker than chemical bonds, and they hold molecules in a condensed phase like a liquid or a solid. The forces of attraction between the iodine atoms in I2 are much weaker than the forces of attraction between the fluorine atoms in F2.

As a result, the boiling point of I2 is much lower than the boiling point of F2. F2 is a gas at STP since it is held together by much stronger intermolecular forces than I2 due to its smaller size. Fluorine has an electron density that is spread out over a larger area than iodine, making it more polarizable. The larger polarizability leads to stronger instantaneous dipoles and, as a result, stronger London dispersion forces. Since intermolecular forces are responsible for determining the physical state of a substance, F2 is a gas, whereas I2 is a solid. As a result, F2 has stronger intermolecular forces than I2.
