A. 16
B. 5
C. 32
D. 10

Answer 1

A:16

Step-by-step explanation:

it's one of those things where there is no way to explain it but I hope this helps

Answer 2

c

first balance the chemical equation / the equation is already balanced/

secondly write the given mole above the compound

then place the coefficient as a number of mole under the compound

after that set up the proportion

finally calculate the unknown mole

x/16 = 10/5

x=32
