Hydrogen peroxide ( H2O2 ) is used on cuts and scrapes to kill bacteria that could enter the body and cause an infection. When hydrogen peroxide is poured on a cut, it comes into contact with an enzyme called catalase. In a chemical reaction, the hydrogen peroxide breaks down into water and oxygen gas. Select the correct number from each menu below to construct a balanced chemical equation that represents the chemical reaction.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
