Answer : To balance a chemical equation you need to find the same number of molecules on both the sides of the reaction.
Here in the reaction ;
here we can see that I is not balanced so we need to balance that,
also nitrate is unbalanced we need to work on that as well.
so on solving we get,
Answer:
wind has resistance, 10 mph of wind has more than 0 mph
How many atoms of oxygen are represented in 2Fe(NO3)2?
Answer: 12
Answer:
<em>C</em> Na+ = 0.228 M
Explanation:
M 2M M
∴ mol Na2S = (0.0478 L)*(0.801 mol/L) = 0.0383 mol
∴V sln = 336.7 mL = 0.3367 L
⇒ <em>C</em> Na2S sln = 0.0383 mol / 0.3367 L = 0.114 M
∴ mol Na+ = (0.0383 mol Na2S)*( 2 mol Na+/ mol Na2S) = 0.0766 mol
⇒ <em>C</em> Na+ = 0.0766 mol / 0.3367 L = 0.2275 M
