Balance the following chemical reaction (or 'equation'): ca+ci--> caci2 the 2 is a lower 2. ca+ci--> caci, ca+ci2 lower 2--> caci2 lower 2 , ca+2ci--> caci2 lower 2

Answer : The balance chemical reaction is,

Explanation :

Balanced chemical reaction : It is defined as when the number of different atoms of elements in the reactant side is equal to that of the product side.

The balanced chemical reaction is,

In this reaction, calcium metal react with chlorine gas to give calcium chloride.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
