The specific heat is 0.401 J/(g x C). The specific heat is the amount of heat of one unit mass of an object required to raise the temperature by one degree Celsius. The specific amount can be calculated using Cp = Q/(m x changes in T) formula, where Cp is the specific heat, Q is the amount of heat, m is the object's mass, and changes in T is the changes in temperature<span>.</span>

A certain weak acid, ha, has a ka value of 6.0×10−7. calculate the percent ionization of ha in a 0.10 m solution.
joja [24]
For the purpose, we will use the equation for determining the dissociation constant from concentration and <span>percent of ionization:

Kd = c </span>× α²

α = √(Kd/c) × 100%

Kd = 6.0×10⁻⁷

c(HA) = 0.1M

α = √(6.0×10⁻⁷/0.1)  × 100% =  0.23%

So, in the solution, the acid <span>percent of ionization will be just 0.23%.</span>

taurus [48]

Answer:

0.737M

Explanation:

C1V1=C2V2

2.50 x 0.442 = C x 1.5

1.105 = C x 1.5

C = 1.105/1.5

C = 0.737M
