382.75 is the temperature of the 0.750 mol of an ideal gas occupy a volume of 35.9 L at 114 kPa.

Explanation:

Given:

number of moles (n) = 0.750

volume of the gas = 35.9 litres

pressure on the ideal gas = 114 kPa or 1.125 atm

R (gas constant) = 0.0821J/Kmole

Absolute temperature of gas in celcius =?

the equation for the ideal gas is

PV = nRT

putting the values in the above equation:

T = $\frac{PV}{RT}$

= $\frac{1.125 X 35.9}{0.75 X 0.0821}$

= 655.907

655.9 kelvin is the temperature of the ideal gas.

To convert this unit of kelvin into degree celcius:

K-273.15 = C

655.9 - 273.15

= 382.75 degrees

382.75 degrees celcius is the temperature of the ideal gas.

1) A mixture of anhydrous sodium carbonate and sodium hydrogencarbonate of mass 10.000 g was heated until it reached a constant

vodomira [7]

The masses of the components are obtained as;

Sodium hydrogen carbonate = 3.51 g
Sodium carbonate = 8.708 g

<h3>What is decomposition?</h3>

The term decomposition has to do with the breakdown of the given substance into its components. The components of sodium hydrogen carbonate could be identified as water vapor, carbon dioxide gas and sodium carbonate. Among these products that have been listed here, we can see that it is only the sodium carbonate that remains as a solid. The others are gases that move away from the system that is under study.

Now putting down the equation of the reaction, we have;

$2NaHCO_{3} (s) ----- > Na_{2} CO_{3} (s) + CO_{2} (g) + H_{2} O(g)$
