dsp732 years ago
3 0

Answer:

Even small amounts of radiation over a prolonged period of time can be dangerous.

Explanation:

We all get exposed to radiation, such as through x-rays, and it's fine as one off experiences. However, if you're constantly dealing with radiation without any sort of protection, no matter how small the amount is, it could potentially lead to consequences like cancer. This is due to the fact that radiation can alter our genes

When hydrogen gas reacts with oxygen gas under certain conditions to produce liquid water, 572.0 kJ of heat energy is released.
frozen [14]

Answer : This reaction is an exothermic reaction.

Explanation :

Endothermic reaction : It is defined as the chemical reaction in which the energy is absorbed from the surrounding.

In the endothermic reaction, the energy of reactant are less than the energy of product.

Exothermic reaction : It is defined as the chemical reaction in which the energy is released into the surrounding.

In the exothermic reaction, the energy of reactant are more than the energy of product.

Enthalpy of reaction : It is the difference between the energy of product and the reactant. It is represented as \Delta H.

The balanced chemical reaction will be:

H_2(g)+O_2(g)\rightarrow H_2O(l)+572.0kJ

From the reaction we conclude that the heat energy is released during the reaction that means this reaction is an exothermic reaction.

Hence, the reaction is an exothermic reaction.
