Answer:

2HClO4 + Ca(OH)2 = Ca(ClO4)2 + 2H2O

Explanation:

Formula for aqueous perchloric acid is; HClO_4 (aq)

Formula for aqueous calcium hydroxide is; Ca(OH)_2 (aq)

Thus chemical equation is;

HClO4 + Ca(OH)2 = Ca(ClO4)2 + H2O

We have to balance it and so we now have;

2HClO4 + Ca(OH)2 = Ca(ClO4)2 + 2H2O

what is the ratio of the rate of effusion of helium (atomic mass 4.00 amu) to that of oxygen gas (molecular mass 32.0 amu)?
nignag [31]

Answer:

3 : 1

Explanation:

Let the rate of He be R1

Molar Mass of He (M1) = 4g/mol

Let the rate of O2 be R2

Molar Mass of O2 (M2) = 32g/mol

Recall:

R1/R2 = √(M2/M1)

R1/R2 = √(32/4)

R1/R2 = √8

R1/R2 = 3

The ratio of rate of effusion of Helium to oxygen is 3 : 1
