<u>Answer:</u> The volume of given mas of tin block at STP is 13.0cm^3

<u>Explanation:</u>

To calculate volume of of the substance, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

We are given:

Mass of tin = 95.04 g

Density of tin = 7.31g/cm^3

Putting values in above equation, we get:

7.31g/cm^3=\frac{95.04g}{\text{Volume of tin}}\\\\\text{Volume of tin}=\frac{95.04g}{7.31g/cm^3}=13.0cm^3

Hence, the volume of given mas of tin block at STP is 13.0cm^3

(ii) When shale gas is burned, the hydrogen sulfide reacts with oxygen.
Elenna [48]

Answer:

See explanation

Explanation:

Now , we have the equation of the reaction as;

2H2S(g) + 302(g)------->2SO2(g) + 2H2O(g)

This equation shows that SO2 gas is produced in the process. Let us recall that this same SO2 gas is the anhydride of H2SO4. This means that it can dissolve in water to form H2SO4

So, when SO2 dissolve in rain droplets, then H2SO4 is formed thereby lowering the pH of rain water. This is acid rain.

How many moles of gas would you have if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature
seraphim [82]

Answer: There are 3.2 moles of gas if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature.

Explanation:

Given: Volume = 38.0 L

Pressure = 1430 mm Hg (1 mm Hg = 0.00131579 atm) = 1.9 atm

Temperature = 273.15 K

Using ideal gas equation, the moles of gas will be calculated as follows.

PV = nRT\\

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T =temperature

Substitute the values into above formula as follows.

PV = nRT\\1.9 atm \times 38.0 L = n \times 0.0821 L atm/mol K \times 273.15 K\\n = \frac{1.9 atm \times 38.0 L}{0.0821 L atm/mol K \times 273.15 K}\\= 3.2 mol

Thus, we can conclude that there are 3.2 moles of gas if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature.

The volume of gas is 252 mL at 340.0 kPa pressure. What will the volume be when the pressure is reduced to 50.0 kPa? Temperature
MrRissso [65]

Answer:

Clearly volume will INCREASE almost sevenfold, as we would expect if we reduce the pressure. Marilia E.K. The final volume of this gas will be 1.7L.
