Balance and evaluate the following equation: agno3 (aq) + pbbr2 (s) yields agbr (s) + pb(no3)2 (aq)

The balance equation is given as:

Explanation:

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

The balance equation is given as:

According to reaction,2 moles of silver nitrate react with 1 mole of lead (II) bromide to give 2 moles of silver bromide and 2 moles of lead nitrate.

When aqueous silver nitrate reacts with solid lead(II) bromide it gives solid precipitate of silver bromide and aqueous solution of lead(II) nitrate.

- 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
