Explanation:
First, let's rewrite the equation here:
4 NH3 + 6 NO -> 5 N2 + 6 H2O.
The equation tells us that 6 moles of NO produces 5 moles of N2.
But the question wants us to find the quantity in grams of NO required if we have 121 g of N2.
1. So first, let's transform 121 g of N2 into moles, using its molar mass (28 g/mol) and the following formula: moles = mass/molar mass
2. Then, we use the equation ratio between NO and N2: 6:5.
3. Then we transform the result into grams of NO, using its molar mass (30.01 g/mol) and the following formula: mass = moles*molar mass
1. moles = 121/28
moles = 4.3 moles of N2
2. 6 moles of NO --- 5 moles of N2
x moles of NO --- 4.3 moles of N2
5x = 4.3*6
x = 25.9/5
x = 5.2 moles of NO
3. mass = 5.2*30.01
mass = 155.6 g
Answer: It will require 155.6 g of NO.
The correct answer is 53.
It would be neutral if they were both at 53, however, since there's 54 electron, then it becomes negatively electrified and becomes -1. You just delete one number from it and you'll see that it's 53.
The first answer; Nickel has an atomic number of 28 (28 protons). and cobalt has an atomic number of 27 (27 protons).
The correct option is A.
As part of the Clean Air Amendment, the government mandated industries to build emission stacks, through which pollutant can be released high into the air in order to prevent pollution of the local community. But this had resulted into interstate pollution, because at high altitudes, the wind carry the pollutants far away into other states or areas.
