Answer:
10
Explanation:
you need to balance the reaction. the left must be equal to the fight hànd. multiply both sides by 2
According to provided equation it is clear that Zn metal is oxidized from Zn⁰ into Zn²⁺ which means that Zn metal dissolves and forming Zn²⁺ solution so the correct answer is:
mass of the Zn(s) electrode decreases
ANSWER
The temperature at which it boils is a measure of its physical property
STEP-BY-STEP EXPLANATION:
Firstly, we need to define the physical and chemical property of matter
The physical property of matter is characteristic of matter that is not associated with a change in its chemical composition. The physical properties include; <em>color, density, hardness, melting, and boiling point.</em>
The chemical property of matter is characteristic of matter that is associated with a change of matter from one type to another type. The chemical properties include; <em>Flammability, toxicity, acidity, reactivity, etc.</em>
When a liquid is boiled, it changes its state from liquid to vapor, this change of state is associated with the physical property of matter.
Hence, the temperature at which it boils is a measure of its physical property
Some of the individual pressures that are exerted by two or more gases.
The answer would be A because first, B is an exothermic reaction. C also describes an exothermic reaction because energy is released. There is an exchange of energy between the sun and the plant, therefore it is not the last answer either.
