How many milliliters of 0.580 m aluminum bromide solution are required to prepare 89.3 ml of a solution that is 0.233 m in bromide ion?

The initial volume is 35, 9 ml

Explanation:

We use the formula:

V initial  x C Initial  = V Final  x C Final   , being V = volume and C = concentration

V initial x 0, 580 M = 89, 3 ml x 0, 233 M

V initial = (89, 3 ml x 0, 233 M)/0, 580 M = 35, 9 ml

- 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
