The answer is true. One neutral atom of carbon has four valence electrons.
An easy way of finding out is to check out the periodic table and look at which main number group the element is in. Carbon is in group number four, which would mean it has four valence electrons.
Hope I was able to help!

3. be
Explanation:
it shows it in the word search
Number of moles = number of atoms/Avogadro's number
= (4.8x10^25)/(6.02x10^23)
=79.7 mol (3sf)
Answer:
In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
Endothermic is when the compound absorbs energy in the reaction. Exothermic is the opposite: the compound releases energy in the reaction.
