Answer:
Magnesium loses two electrons.
Explanation:
- As clear from the reaction Mg converted from <em>Mg(s) to Mg²⁺</em>, so Mg converted from the oxidation state (0) to (2+).
<em>∴ Mg losses two electrons.</em>
- Cl⁻ remains as it is, so it is considered as a catalyst and neither loss nor gain any electrons.
<em>So, the correct choice is Magnesium loses two electrons.</em>
Answer:
a- The paper towel with more thermal energy
Explanation:
The paper towel with a higher temperature is one with more thermal energy.
Temperature is the degree of hotness or coldness of a body. And it is a measure of the average kinetic energy of the particles within a medium or body.
As body gains more thermal energy which is a form of kinetic energy, the average kinetic energy of its particles increases.
This will in turn lead to an increase in the temperature of the substance.
So, the paper towel with more thermal energy will have a higher temperature.
Answer:
25
Explanation:
mass number = protons + neutrons
= 13 + 12 = 25
