Which is a cleaner source of energy? Fission or Fusion? Why?

Answers

Answer 1

Answer: In 1987, the World Commission on Environment and Development (WCED) classified fission reactors that produce more fissile nuclear fuel than they consume (breeder reactors, and if developed, fusion power) among conventional renewable energy sources, such as solar and falling water.

Which changes will decrease the electric force between two positively charged objects? Check all that apply.moving them closer together

moving them farther apart

adding electrons

removing electrons

adding neutrons

removing neutrons

Answers

The changes that will decrease the electric force between two positively charged objects is by moving them closer together and moving them farther apart

Answer : Option B) Moving them farther apart.

Explanation : Force (F) is inversely proportional to distance (D) separated by charges.

$F=(1)/(D^(2))$

When Electrostatic force is found to be inversely proportional between two positive charges which is separated by a distance D, then to decrease the electrostatic force of one can try to change the distance between the two positive charges in such a way that it increases the distance and decreased the electric force. The best option would be to move the them far apart from each other.

Why are atoms always bonded

Answers

Atoms are always bonded so that nearby atoms have to form into a compound and can be classified into different forms of compounds or molecules. It is also integral in our everyday life.

Suppose the gas resulting from the sublimation of 1.00 g carbon dioxide is collected over water at 25.0◦c into a 1.00 l container. What is the total pressure in the container? Express your answer in atmospheres.

Answers

Final answer:

The totalpressure in the container is 1.03 atm, which is the sum of the pressure of the carbon dioxide (1 atm) and the partial pressure of the water vapor (0.03 atm) at 25.0°C.

Explanation:

The question is asking about the total pressure in a container after the sublimation of carbon dioxide at a certain temperature in the presence of water. Carbon dioxide sublimates (turns from solid directly to a gas) at normal atmospheric pressure, which is 1 atm. Sublimation is a phase transition in which a solid turns into a gas without passing through the liquid phase. In this case, the CO2 sublimates and is collected in a container over water.

However, as the gas is collected over water, it also becomes saturated with water vapor. The total pressure in the container is therefore the sum of the partial pressure of the carbon dioxide plus the partial pressure of the water vapor. At 25.0°C, the partial pressure of the water vapor is about 0.03 atm. Therefore, the total pressure in the container will be 1 atm (from the CO2) + 0.03 atm (from the water vapor) = 1.03 atm. This is the total pressure in the container.

Final answer:

The total pressure in the container is 1.03 atmospheres, combining the pressure of sublimated CO2 (1.00 atm) and the vapor pressure of water at 25.0 °C (0.03 atm).

Explanation:

To determine the total pressure in the container containing carbon dioxide and water vapor, we need to consider both the dry gas pressure and the vapor pressure of water. Carbon dioxide sublimes at 1.00 atm at standard atmospheric pressure. However, the gas collected over water becomes saturated with water vapor. The pressure of the pure CO2 gas is therefore equal to the total pressure minus the vapor pressure of the water. The vapor pressure of water at 25.0 °C is approximately 0.03 atm. Therefore, the total pressure in the container is the sum of the pressure due to the carbon dioxide and the water vapor, which equals 1.00 atm + 0.03 atm = 1.03 atm.
