What is the molecularity of the elementary step X + X + Y → Z?

Anna35 [415]

The molecularity of the elementary step X + X + Y → Z is 3.

<h3>What is Molecularity ?</h3>

Molecularity in chemistry is defined as the total number of molecules that react in an elementary reaction .

In the given question the elementary reaction given is

X + X + Y → Z?

or 2X +Y --> Z

X molecule is 2 and Y molecule is 1 so the molecularity is 2+1 = 3

The molecularity of the elementary step X + X + Y → Z is 3.

0.250 moles of NaCl is dissolved in 0.850 L of solution. What is the molar concentration?

Nuetrik [128]

Considering the definition of molarity, the molar concentration is 0.294 $\frac{moles}{liter}$ .

Molarity reflects the concentration of a solution indicating the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

$molarity=\frac{amount of moles of solute}{volume}$

Molarity is expressed in units $\frac{moles}{liter}$ .

In this case, you know:

amount of moles of solute= 0.250 moles
volume= 0.850 L

Replacing in the definition of molarity:

$molarity=\frac{0.250 moles}{0.850 L}$

Solving:

molarity= 0.294 $\frac{moles}{liter}$

Finally, the molar concentration is 0.294 $\frac{moles}{liter}$ .

Naddik [55]

Explanation:

1 kJ = 238.85 cal and

1 cal = 0.004187 kJ

so it will be 78.9×238.85 = 18,844 calories

78.9 Kilojoules (kJ) = 18,844 Calories (IT) (cal)
