Hello there!
In this case, according to the given chemical reaction and the fact that 22.4 L of a gas are occupied by 1 mol at standard pressure and temperature conditions, it will be possible for us to calculate the number of molecules of propane, by using the Avogadro's number, the 1:3 mole ratio with carbon dioxide and the aforementioned volume-mole ratio to obtain:

Answer:
8.88 grams of aluminum nitrate should be weighted.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to use the definition of molarity to calculate the moles of aluminum nitrate as follows:
Now, since the molar mass of aluminum nitrate is 212.996 g/mol, we obtain the following mass:
Therefore, 8.88 grams of aluminum nitrate should be weighted.

Answer : The main function of the control rods in a nuclear power plant is to absorb the unwanted extra neutrons emitted after the nuclear fission reaction, as to slow down or completely shut down the reaction in case of certain emergencies.
The main idea is to prevent uncontrolled chain reactions which occurs in nuclear fission reactors. The important characteristic of a control rod should be made of a material which does not undergoes fission.

hope it make sense to u :)
