Answer:
The solution with [OH-] = 3.2x10-3 M will have an [H+] of 3.09x10–12 M.Explanation:
Answer:- Specific heat of glass is 
.
Solution:- It asks to calculate the specific heat of glass when 13.4 J of heat is required to heat 8.0 g of water by 2.0 degree C.
The equation used for solving this type of problems is:
where, q is the heat energy, m is the mass, c is specific heat and 
is change in temperature.
From given info:
q = 13.4 J
m = 8.0 g
= 2.0 degree C
c = ?
Let's plug in the values in the equation and solve it for c:
On rearrangement:
So, the specific heat of glass is .
