Answer:
Step 1 H2 + 2 NO → N2O + H2O (slow)
step 2 N2O + H2 → N2 + H2O (fast)
Explanation:
It is known that the slowest step in a reaction is the rate determining step in a sequence of reactions (reaction mechanism).
We have two important pieces of information in the question to guide our decision making process.
The overall reaction equation, and the rate expression. The two;
2 H2 + 2 NO → N2 + 2 H2O and rate = k[H2][NO]2 all support the answer given above.
Answer:
a. Oxygen gas is limiting
Explanation:
hydrogen gas and oxygen gas are reacted to form water
2H₂ + O₂ → 2H₂O
the above balanced equation shows that 2 moles of H₂ is required for 1 mole of O₂
Given equal masses of H₂ and O₂
assuming 'x' gm for each, no. of moles of each gas =
no. of moles of H₂ = x/2 = 0.5x moles
no.of moles of O₂ = x/32 = 0.031x moles
This shows that no. of moles of O₂ is very less so O₂ will become the limiting reagent.

Answer:
This question is asking to state the hypothesis for the given scientific question. A possible hypothesis will be:
IF an organized binder is used, THEN students will turn in an increased amount of homework/more homework.
Explanation:
A hypothesis in an experiment is a testable explanation to a problem. It is a predictive statement given in order to provide a possible solution to an observed problem or scientific question. A hypothesis must be subject to testing via experimentation in order to determine whether to accept or reject it. It must not be true, instead it is just a possible answer to a problem. Hypothesis is usually written in the OF, THEN format.
In this question, a scientific question states: How does the use of an organized binder affect the amount of homework a student turns in? Based on the explanation above, a hypothesis to this question will be:
IF an organized binder is used, THEN students will turn in more homework.
