Answer:
Explanation:
To start with, the mass of a substance is centered on the amount of particles contained in it.
Mass of a substance measure is the same anywhere it is taken.
In chemistry, the concept of mole is used to find the exact estimate of the number of entities in a sample.
A mole of substance is quantity that is used to express the number of particles contained in it.
1 mole of any substance contains the Avogadro's number of particles.
This amount of particles is given as 6.02 x 10²³; the particles can be protons, neutrons, electrons e.t.c.
To find the number of moles;
Number of moles = 
Through this, we clearly ascertain the number of entities in a sample given the mass.
Answer:
(1) Rate = k[NO2]^2[CO]
(2) The rate of the reaction is 1.195 Ms^-1
Explanation:
(1) Equation of reaction
NO2 + CO = NO + CO2
The reaction is second-order in NO2 and zero-order in CO
Therefore, rate = k[NO2]^2[CO]^0
(2) Rate = k[NO2]^2[CO]^0
k = 0.790 M^-1s^-1
[NO2] = 1.23 M
[CO] = 0.221 M
Rate = 0.79×1.23^2×0.221^0 = 1.195 Ms^-1
Answer:
1. 3.29mol
2. 0.125molH2o/mol
3. 52.5'C
Explanation: The step by step explanation are attached to the answer.
Answer:
Explanation:
Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions.
Plz mark me brainliest.
The answer is d: Combustion, because it is the so-called combustion of methan. (Check your lesson)
