Answer: the pH moves to 0 on the pH scale
Explanation:
A base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydrogen ions in water.
Neutralisation reaction is defined as the chemical reaction in which an acid reacts with a base to produce a salt and water molecule. The
ions from acid are neutralised by
ions from base.
Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH of 7.
Answer:
Number of valence electrons
Explanation:
A family of elements is defined as a specific group of those elements. Groups in the periodic table are identified by columns, e. g., group 1A contains alkali metals, group 2A contains alkaline earth metals, group 7A consists of halogens, group 8A contains noble gases etc.
The group number corresponds to the valence electrons these atoms have. The number of protons for each atom is different and the level of reactivity depends on the size of the atom mainly, as well as electronegativity.
Answer:
6.5
Explanation:
No of moles is the ratio of reacting mass to molar mass
RM - 270.4g
MM - 23+16+1= 40g/mol
270.4/40= 6.76mol
- The core, Which are protons (positive) and neutrons (neutral);
<span>- The Electrosphere, Which are electrons (negative);
