Answer:
0.287 mole of PCl5.
Explanation:
We'll begin by calculating the number of mole in 51g of Cl2. This is illustrated below:
Molar mass of Cl2 = 2 x 35.5 = 71g/mol
Mass of Cl2 = 51g
Number of mole of Cl2 =..?
Mole = Mass /Molar Mass
Number of mole of Cl2 = 51/71 = 0.718 mole
Next, we shall write the balanced equation for the reaction. This is given below:
P4 + 10Cl2 → 4PCl5
Finally, we determine the number of mole of PCl5 produced from the reaction as follow:
From the balanced equation above,
10 moles of Cl2 reacted to produce 4 moles of PCl5.
Therefore, 0.718 mole of Cl2 will react to produce = (0.718 x 4)/10 = 0.287 mole of PCl5.
Therefore, 0.287 mole of PCl5 is produced from the reaction.
Answer:
Different types
Explanation:
Because it's in a different place
It's a radioactive chemical element. It's symbol is AM and the atomic number is 95. It is a transuranic member of the actinide series, in the periodic table located under the lanthanide element europium, and thus by analogy was named after the Americas.
The chemical reaction involving Mg(OH)2 and HCl is:
<span>Mg(OH)2 + 2HCl
--> MgCl2 + 2H2O</span>
So we see that for every 2 moles of HCl, 1 mole of Mg is
reacted.
Calculating for moles HCl:
moles HCl = 0.300 M * 0.215 L
moles HCl = 0.0645 mol
The moles Mg then is:
moles Mg = 0.0645 mol * (1 / 2)
<span>moles Mg = 0.03225 mol</span>
