Answer:
The answer would be A because inside of an atom is protons and neutrons. Protons are + neutrons are neutral and electrons are -. The electron cloud is big not small.
Explanation:
Hope this helps, have a great day. God Bless you.
Explanation:
When a substance or solution has pH equal to 7 then it is known as a neutral solution. And a solution with pH more than 7 is basic in nature.
Antacid is a base that has chemical formula
and it is also known as magnesium hydroxide.
Hence, an antacid has pH greater than 7 (making it basic) so that it can neutralize the acid.
Therefore, when excess of acid is formed in the stomach then there occurs more hydrogen ions. Due to which pain is felt in the stomach and in this situation when an antacid is consumed then it releases hydroxide ions as it is a base due to which acid gets neutralized and we feel relieved.
Hence, we can conclude that the pH of an antacid solution that is used to neutralize excess stomach acid is more than 7.
