Suppose that you lowered the temperature of a gas from 100˚C to 50 ˚C. By what factor do you change the volume of the gas?
Maru [420]

Answer:- Volume decreases by a factor of 1.15.

Solution:- At constant pressure, volume of the gas is directly proportional to the the kelvin temperature.

The equation is written as:

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where, V_1 is the volume at initial temperature T_1 and V_2 is the volume at final temperature T_2 .

Temperature must be in kelvins. So, let's convert both the temperatures to kelvin.

To convert degree C to kelvin we add 273.

So, T_1  = 100 + 273 = 373 K

T_2 = 50 + 273 = 323 K

The equation could also be written as:-

\frac{V_1}{V_2}=\frac{T_1}{T_2}

\frac{V_1}{V_2}=\frac{373}{323}

\frac{V_1}{V_2} = 1.15

From here we could say that the volume decreases by a factor of 1.15.

For example if the initial volume V_1 is 1 L then final volume V_2 will be \frac{1L}{1.15} that is 0.87 L.

How much HCl is produced from the reaction of an excess of HSbCl4 with 3 moles H2S in the following reaction? HSbCl4 + H2S → Sb2
Fudgin [204]

Answer:

We will produce 8.0 moles of HCl , this is 291.7 grams HCl

Explanation:

Step 1: Data given

Number moles of H2S = 3.0 moles

Step 2: The balanced equation

2HSbCl4 + 3H2S → Sb2S3 + 8HCl

Step 3: Calculate moles HCl

For 2 moles HSbCl4 we need 3 moles H2S to produce 1mol Sb2S3 and 8 moles HCl

For 3.0 moles H2S we'll have 8.0 moles HCl

Step 4: Calculate mass HCl

Mass HCl = moles HCl * molar mass HCl

Mass HCl = 8.0 moles * 36.46 g/mol

Mass HCl = 291.7 grams

We will produce 8.0 moles of HCl , this is 291.7 grams HCl
