The answer is C. There needs to be equal numbers of protons and electrons. If there are more or less electrons then the atom is no longer neutral!
The number of electrons will equal the number of protons In a neutral atom and the number of protons is the atomic number.
The first step Niven has to do
in his calculation is to Balanced the chemical equation. The answer is letter
A. The key in the balancing of chemical reaction is to make sure that you got
the exact chemical formula of the substance that is reacting and the yielded
product. After getting the formula, identify first the hardest element/atom to
be balanced such as Na, Zn, Cl, etc. Then proceed to the easier ones such as O,
H. Make sure to not the atoms present in the molecule of the substance.
Thank you for posting your question here. To answer that question, an acid is a substance that contains hydrogen. It usually has a sour taste and also can able to neutralize alkali and reddening blue litmus paper. The hydrogen that it contains can be replaced by a metal.
