A sample of 79.3 g of hydrogen bromide is reacted with 80.0 g of barium hydroxide to produce barium bromide and water. Using the balanced equation below, predict which is the limiting reactant and the maximum amount in moles of barium bromide that can be produced 2HBr + Ba(OH)2 → BaBr2 + 2H2O

A. Hydrogen bromide, 0.490 Moles
B. Hydrogen bromide, 0.565 moles
C. Barium Hydroxide, 0.467 Moles
D. Barium Hydroxide, 0.624 moles

- 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

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d

it would be a gas formation
