Answer:
Calcium for 2+ charge and Fluorine forms 1- charge
Explanation:
The law of conservation of mass maintains that in all chemical reactions mass is conserved, this ensures that chemical reactions are balanced.
<h2>What is the law of conservation of mass?</h2>
It is a principle of chemistry that states that the quantities of the masses involved in a given reaction must be constant, that is, the quantity of reactants consumed is equal to the quantity of products formed.
<h3>Characteristics of the law of conservation of mass:</h3>
- The chemical composition of a substance remains constant.
- In a chemical reaction certain coefficients are used to balance the equation and this will allow the number of atoms to be equal on both sides.
Therefore, we can conclude that the law of conservation of mass is the one that holds that, within a closed system, the amount of matter before and after a transformation is always the same.

Chemical I’m learning that stuff too :)
Answer:
A volumetric pipette is used to measure 25.0cm3 of 2.0mol/dm3 aqueous sodium hydroxide into aconical flask.
A burette is filled with dilute sulfuric acid.
Write a balanced symbol equation for the reaction between these chemicals when we neutralise.
Explanation:
The reactants of the given reaction are:
sodium hydroxide and dilute sulfuric acid.
The balanced chemical equation of the reaction is:

Acid and base raect with each other and form salt and water.
This reaction is called a neutralization reaction.
