Answer:

T(final) = 40.4 °C

Explanation:

Given data:

Density of water = 1.00 g/mL

Volume of water at 25°C = 390.0 mL

Volume of water at 95°C = 110.0 mL

Final temperature of mixture = ?

Solution:

Heat absorbed by warm water = heat lost by hot water

q lost = -q lost ....... (1)

Formula:

q = m.c.ΔT

ΔT(warm) =  T(final) - 25°C

ΔT(hot) =  T(final) - 95°C

Mass of water:

d = m/v

1 g/mL = m/ 390 mL

390 g = m

For hot water:

d = m/v

1 g/mL = m/ 110.0 mL

110.0 g = m

Now we will put the values in equation 1.

390 g. c.   (T(final) - 25°C) =  - 110.0 g .c. (T(final) - 95°C)

390 T(final) - 9750 °C = -110 T(final) + 10450 °C

390 T(final) +110 T(final) = 10450 °C +9750 °C

500 T(final) = 20200

T(final) = 20200/500

T(final) = 40.4 °C

Consider the reaction below. Initially the concentration of SO2Cl2 is 0.1000 M. Solve for the equilibrium concentration of SO2Cl
tensa zangetsu [6.8K]

Answer:

[SO_2Cl_2] = 0.09983 M

Explanation:

Write the balance chemical equation ,

SO_2Cl_2((g) = SO_2(g) + Cl_2(g)

initial concenration of SO_2Cl_2((g)  =0.1M

lets assume that degree of dissociation=\alpha

concenration of each component at equilibrium:

[SO_2Cl_2] = 0.1-0.1\alpha

[SO_2] = 0.1\alpha

[Cl_2] = 0.1\alpha

Kc =\frac{0.1\alpha \times 0.1\alpha}{0.1-0.1\alpha}

Kc =\frac{0.1\alpha \times \alpha}{1-\alpha}

as \alpha is very small then we can neglect  1-\alpha

therefore ,

Kc ={0.1\alpha \times \alpha}

\alpha =\sqrt{\frac{Kc}{0.1}}

\alpha = 1.73 \times 10^{-3}

Eqilibrium concenration of [SO_2Cl_2] = 0.1-0.1\alpha = 0.1-0.1\times 0.00173

[SO_2Cl_2] = 0.09983 M
