Answer:
For every 4 moles of NO created, 6 moles of H2O are created so the ratio is 4:6
Explanation:
You just need to balance the equation.
NH3 + O2 -> NO + H2O
1. I started with hydrogen; there's 3 on the left and 2 on the right. Multiply them together to find a number they both go into (3×2=6, but in this case 6 hydrogen on each side does not work so I doubled it so there is 12 hydrogen on each side).
This will bring you to this:
4NH3 + O2 -> NO + 6H2O
2. Now get equal amounts of nitrogen on each side. There's 4 nitrogen on the left side, and 1 on the right. Multiply the right by 4. Then you will have this:
4NH3 + O2 -> 4NO + 6H2O
3. Last thing you need to do is have the same amount of oxygen on both sides. On the left you have 2 and on the right you have 10. Get the left to 10 by multiplying it by 5.
Balanced: 4NH3 + 5O2 -> 4NO + 6H2O
In word form, for every reaction between 4 moles of ammonia and 5 moles of oxygen, 4 moles of nitric oxide and 6 moles of water will be created.
I hope this helps!
Answer:
Explanation:
A group of two or more smaller molecules is the correct answer
Explanation:
1.00 mole of O2 contains 2 × 6.023 × 10²³ atoms
= 12.046 × 10²³
In option A
No of oxygen atoms= 0.667 × 3 × 6.023 × 10²³
= 12.046× 10²³ ✓
In option B
No of oxygen Atoms = 1 × 2 × 6.023 × 10²³
= 12.046 × 10²³ ✓
In option C
No of oxygen atoms= 2 × 6.023 × 10²³
= 12.046 × 10²³ ✓
So option D is correct
3NH₃ + H₃PO₄ ======> (NH₄)₃PO₄
1.8 / 98 = 0.018367Mol of phosporic acid
it's a 1:1 ratio 0.08367 x RFM of ammonium phosphate (149) = 12.46g
hope that helps :)
