I need more points but I think it is 84737
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:
4.2 moles of sodium cyanide (NaCN) would be needed to produce 2.1 moles of sodium sulfate (Na₂SO₄).
Explanation:
The balanced reaction is:
H₂SO₄ + 2 NaCN → 2 HCN + Na₂SO₄
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound are necessary:
- H₂SO₄: 1 mole
- NaCN: 2 moles
- HCN: 2 moles
- Na₂SO₄: 1 mole
Then you can apply the following rule of three: if by stoichiometry to produce 1 mole of sodium sulfate 2 moles of sodium cyanide are necessary, then to produce 2.1 moles of sodium sulfate how many moles of sodium cyanide are necessary?
amount of moles of sodium cyanide= 4.2 moles
<u><em>4.2 moles of sodium cyanide (NaCN) would be needed to produce 2.1 moles of sodium sulfate (Na₂SO₄).</em></u>
When the Earth tilts, It puts half of the Earth in Summer and the other half in winter. The half that is faced towards the Sun is Summer, and the side that is faced away is winter. Hope this helps!!
