Answer:

pH = 3; acidic

Explanation:

The equation to find pH given [H+] is:

pH = -log[H+]

In the question it gives us the concentration of [H+], which is 0.0010 M.

Now just plug this into the equation to solve:

pH = -log(0.0010)

pH = 3

This would make the solution acidic as it is less than 7.

Hope this helps!!

Answer:

The combined law is:

$\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$

See the derivation below.

Explanation:

1. Boyle's law:

$PV=constant\\\\P_1V_1=P_2V_2$

2. Charles' law:

$\dfrac{V}{T}=constant\\\\\\\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}$

3. Gay-Lussac’s law

$\dfrac{P}{T}=constant\\\\\\\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}$

4. Summary:

PV = K

V/T = K'

P/T = K''

Mulitply PV by V/T and P/T

$PV\times \dfrac{V}{T}\times \dfrac{P}{T}=K\times K'\times K''\\\\\\\dfrac{P^2V^2}{T^2}=constant\\\\\\\sqrt{\dfrac{P^2V^2}{T^2}}=\sqrt{constant}\\\\\\\dfrac{PV}{T}=constant$

Thus:

$\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$

Which is the combined law.

4NaCl + 2SO2 + _____H2O + _____O2 → _____Na2SO4 + 4HCl

Alik [6]

The numbers that balance the following equation: 4NaCl + 2SO2 + H2O + O2 → Na2SO4 + 4HCl is 2, 1, 2.

BALANCING EQUATION:

Balancing a chemical equation means to make sure that the number of atoms of each element on both sides of the equation are equal.

According to this question, the following chemical reaction are given: 4NaCl + 2SO2 + H2O + O2 → Na2SO4 + 4HCl

Some of the coefficients (numbers) have been placed there while some are missing. The equation that includes the missing coefficients (numbers) to balance the equation is:

4NaCl + 2SO2 + 2H2O + O2 → 2Na2SO4 + 4HCl

In the combined gas law, if the volume is decreased, what happens to the temperature if pressure remains constant?

Flura [38]

The correct answer is A. In the combined gas law, if the volume is decreased and the pressure is constant, then the temperature decreases.

P1V1/ T1 = P2V2 / T2

Assume the volume decrease by half; V2 = V1/2

P1V1/ T1 = P2V1 /2 T2

Cancelling terms,

1/T1 = 1/2 T2

T2 = T1/2

Thus, the temperature decreased.
