Explanation:
Rate law is defined as the rate of a reaction is directly proportional to the concentration of reactants at constant temperature.
![Rate \propto [\text{concentration of reactant}]^{n}](https://tex.z-dn.net/?f=Rate%20%5Cpropto%20%5B%5Ctext%7Bconcentration%20of%20reactant%7D%5D%5E%7Bn%7D)
= k ![[\text{concentration of reactant}]^{n}](https://tex.z-dn.net/?f=%5B%5Ctext%7Bconcentration%20of%20reactant%7D%5D%5E%7Bn%7D)
where, k = rate constant
n = order of reaction
For the given reaction, 
Hence, its rate will be as follows.
Rate = ![k[H_{2}][NO]](https://tex.z-dn.net/?f=k%5BH_%7B2%7D%5D%5BNO%5D)
Also, it is known that slowest step in a chemical reaction is the rate determining step.
Hence, for the given rate law correct reaction is as follows.
Step 1 : 
(slow)
Balancing this equation it becomes 
(slow)
Step 2: 
(fast)
16) 2 servings (4percent Times 2 is 8percent)
17) D; it’s the only choice that can’t be backed up by just looking at the chart
18) A cell wall
19) either A or D but I’m pretty sure it’s D because they help the soil
20) D metabolism
21)c chromosomes because eggs and sperm have 23 chromosomes
Answer:
The Minerals are the <u>chemical substances</u> found on the <u>earth's surface </u>which are <em>elements</em> or <em>compounds</em>.
6 molls
As a result, if two moles of dinitrogen gas are specified, six moles of dihydrogen gas are needed.
Answer:
To summarise, a parent cell divides by mitosis (doubling the DNA then splitting) and then divides again to have 4 daughter cells with all different DNA in and all with only half the amount of DNA as a normal body cell. This stage is meiosis. They make sperams and eggs which fuse together in fertilisation and once fertilised the cell will divide by mitosis to create embryos and further to grow into a fetus.
