Chemistry Matching HW!!!!?

Question

Match the descriptions with the names and symbol/formula of a Group 5A(15) element/compound.

1.)__Element(s) essential in plant nutrition
2.)__Phosphorus-containing water softener
3.)__Hydride produced at multimillion-ton level
4.)__Hydride used to manufacture rocket propellants and drugs
5.)__Amphoteric hydroxide with a 5A element in its' +3 oxidation state
6.)__Two examples of an odd-electron molecule
7.)__Element that is an electrical conductor

a. ammonium, NH 3
b. nitrogen and phosphorus, N & P
c. hydrazine, N 2H 4
d. nitrogen monoxide and nitrogen dioxide, NO & NO 2
e. diarsenium trioxide, As 2O 3
f. sodium tripolyphosphate, Na 5P 3O 10
g. bismuth, Bi

Answer 1

1. B because Nand P are main elements of fertilizers
2. F because look at the formula -polyphosphate
3. A one of the top five chemicals manufactured
4. C hydrazine is a propellant
5. E, As is in 5A group
6. D, count them
7. G is the only metallic element left from choices.

Answer 2

first: 2, because you're eliminating a product (water), notwithstanding i am going to not in any respect use Mg(ClO4)2 as dessiccant in a decomposition reaction, because that's explosive. Mg2(SO4) is barely sufficient. second: 2. The reaction shifts in direction of the products. 0.33: a million once you upload the dry ice, it begins to sublimate, including CO2 (g) to the gadget. fourth: a million for sure, in case you upload stress interior one among those a non reacting gas the reaction search for for an equilibrium, so it would want to wish to lessen the stress and so the reaction shifts in direction of the reactant. (that's strong, instead 2 products are gases)
