1, When temperature is increased the volume will also increase. this is because the particles will gain kinetic energy and bombard the walls of the container of the gas at a higher frequency, therefore, for the pressure to remain constant as per Charles' law, the volume will have to increase so that the rate of bombardment remains constant. This is explained by the Charles law which states that the volume of a gas is directly proportional to the absolute temperature provided pressure remains constant.
2. When temperature is Decreased the volume will also Decrease. this is because the particles will loose kinetic energy and bombard the walls of the container of the gas less frequently, therefore, for the pressure to remain constant as per Charles' law, the volume will have to reduce so that the rate of bombardment remains constant. This is explained by the Charles law which states that the volume of a gas is directly proportional to the absolute temperature provided pressure remains constant.
3. When temperature is increased the pressure will increase. This is because the gas particles gain kinetic energy and bombard the walls of the container more frequently. this is according to Pressure law which states that for a constant volume of a gas the pressure is directly proportional to absolute temperature
4. When temperature is decreased, pressure will decrease, This is because the gas particles lose kinetic energy and bombard the walls of the container less frequently. this is according to Pressure law which states that for a constant volume of a gas the pressure is directly proportional to absolute temperature
5. When particles are added, pressure will increase. This is because the bombardment per unit area also increases. Boyles law explains this, that at fixed temperature the volume of a gas is inversely proportional to the pressure.
6. When particles are removed, the pressure will decrease. This is because the bombardment per unit area also decreases. Boyle's law explains this, that at fixed temperature the volume of a gas is inversely proportional to the pressure.
Answer:
2071g or 2.071kg of rust (Fe3O4)
Explanation:
Step 1:
The balanced equation for the reaction.
3Fe + 4H2O —> Fe3O4 + 4H2
Step 2:
Determination of the mass of Fe that reacted and the mass of the Fe3O4 produced from the balanced equation.
Molar Mass of Fe = 56g/mol
Mass of Fe from the balanced equation = 3 x 56 = 168g
Molar mass of Fe3O4 = (56x3) + (16x4) = 232g/mol
Mass of Fe3O4 from the balanced equation = 1 x 232 = 232g
Summary:
From the balanced equation above,
168g of Fe reacted and 232g of Fe3O4 was produced.
Step 3:
Determination of the mass of rust (Fe3O4) produced when 1.5kg ( i.e 1500g) of Fe reacted.
This is illustrated below:
From the balanced equation above,
168g of Fe reacted to produce 232g of Fe3O4.
Therefore, 1500g of Fe will react to produce = (1500x232)/168 = 2071g of Fe3O4.
From the calculations made above, 2071g or 2.071kg of rust (Fe3O4) is produced.
Given :
Temperature, T = 55° C = ( 55 + 273 ) K = 328 K .
Volume of container, V = 28.9 dm³ = 0.0289 m³ .
Pressure, P = 144 kPa = 144000 Pa .
To Find :
Number of moles of nitrogen gas.
Solution :
We know, by ideal gas equation :
PV = nRT ( R ( universal gas constant ) = 8.31 J K⁻¹ mol⁻¹ .
Therefore, number of moles of nitrogen gas is 1.53 moles.
