It depends of the temperature and the pressure. If temperature and pressure are standard 1 mol forms 22.4 liter. So 33.6 liters form 33.6/22.4 = 1.5 mols.
Now calculate the molar mass of carbon dioxide: 12 g/mol + 2x16 g/mol = 44 g/mol
The mass of the 1.5 mols is 1.5mol * 44 g/mol = 66 g.
Answer:
The average pressure in the container due to these 75 gas molecules is
Explanation:
Here Pressure in a container is given as
Here
- P is the pressure which is to be calculated
- ρ is the density of the gas which is to be calculated as below
Here
mass is to be calculated for 75 gas phase molecules as
Volume of container is 0.5 lts
So density is given as
- is the mean squared velocity which is given as
Here RMS is the Root Mean Square speed given as 605 m/s so
Substituting the values in the equation and solving
So the average pressure in the container due to these 75 gas molecules is
<h3>Answer:</h3>
<u>Breaking</u> chemical bonds requires energy and <u>forming</u> chemical bonds releases energy.
<h3>Explanation:</h3>
Bond Breaking is an endothermic reaction and requires energy. This energy provided to break the bond is called as bond energy. Hence, this is a non spontaneous reaction as it doesn't takes place on its own but requires energy to break them into smaller fragments.
While, Bond Forming is an exothermic reaction. When two substances come close together the formation of bond results in the release of energy. As the resulting product is stable hence, it will be lower in energy as compared to the sum of energies of the reactants. Therefore, the surplus energy is released in the form of heat.
HCl is the limiting reactant, and 3.5 mol H2<span> can be formed</span>
