The nucleus of a atom contains the protons and the neutrons all most all of the atoms mass is weigh by the protons and the neurons.
Answer:
He had the most potential energy going down hill
Explanation:
because he picked up he went faster
Hydrocarbons are carbon and hydrogen. Methane is CH4, and propane is C3H8. Methene is CH3, and propene is C3H6. Carbohydrates are hydrates of carbon. They <span>have the general formula (CH2O)x. thats how it differs
</span>
mol=35:101.11 g/mol=0.346
formula units = 0.346 x 6.02 x 10²³ = 2.082 x 10²³
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.
