Answer:

The answer is D. gamma rays

Explanation:

A radioactive atom can have three different types of emission:

alpha particles (α) = they have a mass of 4 amu and they have a very low penetrating power.

Beta particles (β) = they have 5x $10^{-4}$ amu and they have an intermediate penetrating power

Gamma rays (γ) = they are not particles basically just energy so its mass is ≈ 0 and its penetrating power is higher

For this reason Gamma emissions (γ) has the smallest mass value.

Explanation:

(A) Renewable resources are defined as the resources that can be used again and again.

For example, wind, hydroelectric energy, geothermal etc.

On the other hand, resources which cannot be used again and again and which cannot be replaced by natural means are known as non-renewable resources.

For example, coal, petroleum etc are all non-renewable resources.

Therefore, given options are distinguished as follows.

Renewable energy : Wind, Hydroelectric, Geothermal, Biomass, and Solar.

Non-renewable energy : Coal, Petroleum, Natural gas.

(B) Fuels which decompose for a long period of time and which arise from old life forms are known as fossil fuels.

When fossil fuels burn in the presence of air that is, combustion of fossil fuels give carbon dioxide and water.

Luda [366]

Answer:

0.800 mol of O2

Explanation:

<em>Calculate the moles of oxygen produced by the reaction of 0.800mol of carbon dioxide.</em>

The balanced equation for the reaction is given as;

6CO2 + 6H2O → C6H12O6 + 6O2

From the reaction;

6 mol of CO2 produces 6 mol of O2

0.0800 mol of CO2 would produce x mol of O2

6 = 6

0.0800 = x

Solving for x;

x = 6 * 0.800 / 6

x = 0.800 mol
