As long as there is some oxygen, the reaction will occur. If there is an insufficient amount of oxygen, then the oxygen will be the limiting reacting and there will be excess of the other reactants.
Answer:
it is 55.84
Explanation:
it's 55.84 because that is the relative atomic mass of iron and iron is the formula for iron wool
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.
Answer:
Mercury is an liquid metal
Explanation:
Mercury is a chemical element with the symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum.
Symbol: Hg
Answer:
1.5 moles of Ca²⁺ and 3 moles of NO₃⁻
Explanation:
This is the dissociation:
Ca(NO₃)₂ → Ca²⁺ + 2NO₃⁻
1.5 moles of salt will have the same moles of ion Ca²⁺ and the double of moles, of nitrate according to the equation.
Therefore will be 1.5 moles of Ca²⁺ and 3 moles of NO₃⁻
