How many liters of 0.85 M HCI solution would react completely with 3.5 moles Ca (OH)2?

Chemistry

7 0
Ca(OH)2+2HCL=CaCl2+2H2O
So the molar ratio between ca(oh)2 and hcl is 1 is to 2
Thus with each mole of ca(oh)2 the 2 moles of hcl will react
As a result for a complete reaction we need 7 mole of HCL 
Molarity of hcl is 0.85 
so number of litres of hcl needed would be 8.2 as
number of moles of hcl=8.2x0.85=7moles
So 
ANSWER IS B 8.2 L OF HCL

Answer:

d . Sc2O5

Explanation:

Hello,

In this case, when forming oxides from a metal and oxygen, for us to find out each element's subscript, we must exchange them as shown below, considering +5 for scandium:

Sc^{+5}_2O^{-2}_5

For that reason, the answer is d . Sc2O5

Best regards.

Answer:

b. 6.02 x 1023 molecules

Explanation:

The formula mass of ammonia is 14 + 1 × 3 = 17.

The number of moles in 27.6g ammonia is 27.6 ÷ 17 = 1.62 mol.

A mole is 6.02 × 10²³, so the number of hydrogen atoms in a 1.62 moles of ammonia is 1.62 × 6.02 × 10²³ × 3 = 2.93 × 10² atoms.
