Explanation:
Le Chatelier's principle states that for a long period of time if a system is at equilibrium and it is subjected to change in concentration, temperature, volume or pressure then the system shifts to a new equilibrium.
This change will partly counter acts the applied change.
Therefore, when heat is added to the system then equilibrium will shift to the side where temperature or heat is reduced again.
For example,
Since heat is added to the system, hence, system will shift to the left side or we can say equilibrium will shift to the backward direction.
An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure.
Answer:
Carbon-14 is an isotope of carbon and differs in the number of neutrons in their nucleus.
Explanation:
all isotopes have the same number of protons and electrons, but differ in the number of neutrons. They have identical chemical behaviour but with different atomic masses and physical properties
Answer:
Chlorine gas is the limiting reactant
11.57 g
Explanation:
The equation of the reaction is;
2Al(s) + 3Cl2(g) -----> 2AlCl3(s)
The limiting reactant will produce the least number of moles of AlCl3.
For Al
Number of moles reacted = 2.43 g/27 g/mol = 0.09 moles
2 moles of Al yields 2 moles of AlCl3
0.09 moles of Al yields 0.09 * 2/2 = 0.09 moles of AlCl3
For Cl2
9.22g/71g/mol = 0.13 moles
3 moles of Cl2 yields 2 moles of AlCl3
0.13 moles of Cl2 yields 0.13 * 2/3 = 0.087 moles of AlCl3
Hence Cl2 is the limiting reactant
b) Mass of product produced = 0.087 moles of AlCl3 * 133g/mol = 11.57 g
