find the activity coefficient of h , in a solution containing 0.010 m hcl plus 0.040 kclo4. what is the ph of the solution?
Lisa [10]

The activity coefficient of h is 0.05

The ph of the solution is 2.08

To find the activity coefficient, apply the concept of ionic equilibrium

h( activity coefficient)= 1/2CZ²

C is the concentration of species

Z is the charge on individual species

<em>h= 1/2( 0.01 x1²+ 0.04x (-1)²+0.01 x1²+0.04x (-1)²)</em>

<em>h= 0.05 </em>

For the pH of the solution, apply the formula

<em>pH= -log( H⁺x0.83)</em>

<em>pH = - log(0.01x0.83)</em>

<em>= 2.08</em>

A very hot cube of copper metal (32.5 g) is submerged into 105.3 g of water at 15.4 0C and it reach a thermal equilibrium of 17.
zysi [14]

Answer:

The initial temperature of the metal is 84.149 °C.

Explanation:

The heat lost by the metal will be equivalent to the heat gain by the water.  

- (msΔT)metal = (msΔT)water

-32.5 grams × 0.365 J/g°C × ΔT = 105.3 grams × 4.18 J/g °C × (17.3 -15.4)°C

-ΔT = 836.29/12.51 °C

-ΔT = 66.89 °C

-(T final - T initial) = 66.89 °C

T initial = 66.89 °C + T final

T initial = 66.89 °C + 17.3 °C

T initial = 84.149 °C.
