Answer:
A catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction. A catalyst will appear in the steps of a reaction mechanism, but it will not appear in the overall chemical reaction (as it is not a reactant or product).
Answer:
81.8 %
Explanation:
The balanced equation for the reaction is
⇒ ![2 NH_3](https://tex.z-dn.net/?f=2%20NH_3)
So to find the number of moles of
we do 6.04kg ÷ 2 = 3.02 moles.
The mole ratio between
and
is 3:2. So to find the number of moles you do
× 2 which gives you 2.0124 moles.
Then you find the mass by doing moles multiplied by Mr: 2.0124 x 17 which gives you 34.21 kg.
Then to find the percentage yield you do:
x 100 = 81.82.......
Which is 81.8 %
C. transition, as they show variable oxidation states.
They are carbohydrates!!
If you could help me out by marking this as brainliest I would really appreciate it!! I'm trying to level up
Answer:
Cl
Explanation:
Because the oxidation state reduces from+3 in ClO2- to +1 in ClO- and oxygen is being lost
