Answer:
8 moles of CO
Explanation:
To produce carbon monoxide we begin from C and O₂ as this reaction shows:
2C + O₂ → 2CO
Therefore, 2 moles of C can produce 2 moles of CO
If I have 8 moles of C, I must produce 8 moles of CO
Ratio is 1:1
Answer:
Volume of the rock, V = 2 mL
Explanation:
It is given that,
Water filled in a graduated cylinder is 3 mL
She then drops a small rock into the cylinder and the water level rises to the 5 mL mark
We need to find the volume of the rock.
The volume of the rock is equal to the difference in volume mark. So,
V = 5 mL - 3 mL
V = 2 mL.
Answer:
D
Explanation:
If you look at the problem, and the coefficients (the little numbers on the bottom) you will see that on the reactant side you get a total of 11, you look over to the product side and you also get a total of 11.
B. is wrong because they’re are the same amounts
C.is wrong because they have the same amount of carbon
D. Now similar to B but slightly different the matter is the reactant side I’m pretty sure is equal to the amount on the product side.
If I had to take a strong guess though I would choose D just because the question is asking for the one that shows The law of conservation of mass. Pls make me brainlist
The balanced chemical equation is :
5P₄ + 36OH → 12HPO₃⁻² (aq) + 8PH₃ (acidic)
Here the oxidation number of P changed from 0 to -3 in PH₃ and increases from 0 to +3 in HPO₃⁻². When P₄ changes to PH₃ reduction reaction is taking place as there is addition of hydrogen and when P₄ changes to HPO₃⁻² oxidation takes place as there is addition of oxygen.
Thus clearly both reduction and oxidation are taking place.
Thus, we can infer that here P₄ is both oxidizing as well as reducing agent.
