Answer:

d.

Explanation:

H2 + Cl2 = 2HCL

From the equation 2g hydrogen combine with 71g of chlorine.

So 35.5 g Cl2 combines with 1g of H2

There are 100g of Cl2 so this will, by proportion, react with 100/35.5 g hydrogen.

This is 2.8 g hydrogen so the mass of HCl formed = 102.8 g.

Calculate the molar mass of RbOH
Ghella [55]

Hey there!

RbOH

Rb: 1 x 85.468 = 85.468

O:  1 x 16 = 16

H: 1 x 1.008 = 1.008

------------------------------------

                   102.476

The molar mass of RbOH is 102.476 g/mol.

Hope this helps!

What is the pH of 0.0086M LiOH solution
Tcecarenko [31]
The strong base will be dissociated completely into the aqueous solution. The pOH of the solution can be determined by the concentration of the hydroxide ion. The strong bases have lower pOH value.
