The middle carbon is 4-degree since it is attached to 4 carbons. All other carbons are 1-degree since they are attached to only 1 carbon.

Hydrogens attached with 1-degree carbon are all same. Hydrogen are often refereed to as protons. No carbon is attached to 4-degree carbon. So all hydrogens in this structure are same.

This structure is called NeoPentane

If the rate-determining step of a reaction is This is an image of a chemical equation. A + 2B, reaction arrow, C. , the reaction

ololo11 [35]

The reaction rate of a chemical reaction is determined by the slow step in the reaction mechanism.

The rate ii given by the product of the species of the determining step, each raised to its coeeficient in the chemical reaction that represents this step.

So, given that the determining step is represented by A + 2B→C, the reaction rate is r = k[A]*[B]^2.

This mechanism is verified becasue the total order is the summ of the coefficientes : 1 + 2 = 3 and the exponent 2 makes B is a bigger rate determinant than A.

So, the answer is the option b. k[A][B]^2.

How many atoms are in 35 grams of table salt

Slav-nsk [51]

Adopting the number of avogrado 6.02 * 10²³ / mol
Sodium chloride (table salt) Molar Mass = 58.44 g / mol
We will first have to find the number of moles in 35 grams of the element, like this:

1 mol ----------------- 58.44 g
X ---------------------- 35 g

58.44 * x = 35 * 1
58.44x = 35
$X = \frac{35}{58.44}$
X = 0.598904...
X ≈ 0.60 mol 

Now we will find how many atoms there are in 0.60 mol of this element, like this:

1 mol -------------------- 6.02 * 10²³ atoms
0.60 mol ----------------- X

X = 0.60 * 6.02 * 10²³
$\boxed{\boxed{x \approx 3.612 * 10^{23}\:atoms}}\end{array}}\qquad\quad\checkmark$
