Which best explains the effect of reforestation on land? A. It allows crops to grow in wide steps along slopes.
B. It turns land slowly into desert.
C. It turns habitable land uninhabitable.
D. It restores trees to areas where they once grew.

i think its D: It restores trees to areas where they once grew .

Explanation:

Sorry if it is wrong

D.It restores trees to areas where they once grew.

Explanation:

This is because reafforestation is the process where new tress are planted either natural or intentionally stocking of new tress to areas where the trees has been depleted before or defforested before. It restores new tress to the area or it support the growth of new trees.

D

Explanation: “reforestation” means to bring a forest back and make land habitable again

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
