PIT_PIT [208]3 years ago
7 0

Answer:

<h2>5</h2>

Explanation:

The pH of a solution can be found by using the formula

pH = - log ([ {H}^{+} ])

From the question we have

pH =   -  log(1.0 \times  {10}^{ - 5} )  \\  = 5

We have the final answer as

<h3>5</h3>

Hope this helps you

When a bottle of soft drink is shaken violently, CO2 gas escapes from solution and
jeka94

Answer:

The pressure decrease with the passage of time due to again dissolution of carbon-dioxide gas in the liquid solution.

Explanation:

In soft drinks, the carbon-dioxide gas is added in the drinks with high pressure because carbon-dioxide is a gas which is insoluble in soft drink at room temperature but soluble in the drinks at high pressure so when the pressure is removed from the soft drink, the carbon-dioxide gas releases in the air with the passage of time. But in close bottle , there is no place of escape so it again dissolve in the solution.

Given a fixed amount of gas held at constant pressure, calculate the volume (in L) it would occupy if a 3.50 L sample were coole
Over [174]

Answer:

V₂ = 2.91 L

Explanation:

Given data:

Initial volume = 3.50 L

Initial temperature = 90.0°C (90+273 = 363 K)

Final temperature = 30.0 °C  ( 30 +273 = 303 K)

Final volume = ?

Solution:

V₁ = Initial volume

T₁  =  Initial temperature

V₂ = Final volume

T₂ = Final temperature

V₁/T₁  =  V₂/T₂

3.50 L / 363 K) =  V₂ / 303 K)

V₂ = 0.0096 L/K × 303 K

V₂ = 2.91 L

When hydrogen sulfide reacts with oxygen, water and sulfur dioxide are produced. The balanced equation for this reaction is:
VMariaS [17]

Answer:

2H2S + 3O2 → 2SO2 + 2H2O

Explanation:

Step 1: Data given

Hydrogen sulfide = H2S

Oxygen = O2

sulfur dioxide = SO2

water = H2O

Step 2: The unbalanced equation

H2S + O2 → SO2 + H2O

Step 3: Balancing the equation

H2S + O2 → SO2 + H2O

On the left side we have 2x O (in O2) and on the right side we have 3x O (2x in SO2 and 1x in H2O). To balance the amount of O, we have to multiply O2 (on the left side) by 3 and SO2 and H2O on the right side by 3.

H2S + 3O2 → 2SO2 + 2H2O

On the right side we have 4x H and on the left side we have 2x H. To balance the amount of H, we have to multiply H2S by 2.

Now the equation is balanced.

2H2S + 3O2 → 2SO2 + 2H2O
