12.772 product = multiply
Answer:
621.2090000000001 grams
Explanation:
1 moles Calcium to grams = 40.078 grams
15.5*40.078 = 621.2090000000001 g
Chlorine gas has the the chemical formula Cl2
Solid phosphorus has the chemical formula P4
Phosphorous pentachloride has the chemical formula PCl5
Now the UNBALANCED reaction will be as follows:
P4 + Cl2 ...........> PCl5
We need to balance the equation:
1- We have 4 solid phosphorous atoms as reactants, therefore, the product should have 4 phosphorus atoms as well.
P4 + Cl2 ..............> 4PCl5
2- Now, we have 20 chlorine atoms in the products while only 2 atoms of chlorine as reactants. Therefore, we need to multiply Cl2 by 10 to balance the equation as follows:
P4 + 10Cl2 ...........> 4PCl5
The final balanced equation is as follows:
P4 + 10Cl2 ...........> 4PCl5
