The ratio that show the relationship between moles of each reactant and product in the reaction that is
N2 + 3 H2 = 2NH3
the ratio is as follows
1mole N2 : 3 mol H2 :2mol NH3
This ratio is from equation since there is 1 mole of N2 reacted with 3 moles of H2 to produce 2 moles of NH3
Answer:
They all have 7 valence electrons on it's outer shell.
Answer:
93.15 %
Explanation:
We have to start with the chemical reaction:
Now, we can balance the reaction:
Our initial data are the 15.71 g of 
, so we have to do the following steps:
1) <u>Convert from grams to moles of using the molar mass (110.98 g/mol).</u>
2) <u>Convert from moles of to moles of 
using the molar ratio. ( 1 mol = 1 mol of ).</u>
3) <u>Convert from moles of to grams of using the molar mass. (100 g/mol).</u>
Finally, we can calculate the yield percent:
I hope it helps!
Answer:
B) The group the atom is located
C) There needs to be 2 Na atoms and 1O atom to form Na2O
If you go by the decimal there should be 5 significant digits because 0 is a trailing zero and matters since it comes after a decimal. however if you do
6.3590 x 10 ^7 = 63590000 then you would only have 4 significant digits because there is no longer a decimal to make the zero after the 9, significant.
Hope this helps!
