No, the percent by mass of each element in compound does not depend on the amount of element used to make the compound

The mass percent of each element in a compound is by definition, the compound's percent composition. 100% of the compound is represented by the molar mass. the composition of the elements is fixed in each compound. according do law of multiple proportions different compounds may be formed with same elements but in different proportions.so percent by mass of each element does not depend on amount of element used to make compound

Which electron transition represents a gain of energy?
xz_007 [3.2K]

The correct answer is (A) from 2nd to 3rd shell.


The explanation :


when a gain of energy is the shift of the electrons from a shell of low energy to the shell of high energy


and we have here 2nd shell is the shell of low energy, and 3rd shell is the shell of high energy.


∴ (A) from 2nd to 3rd shell is the correct answer.

The rate constant for a particular zero-order reaction is 0.075 M s-1. If the initial concentration of reactant is 0.537 M it ta
Anarel [89]

Answer:

It takes 5.83s to decrease the concentration of the reactant from 0.537M to 0.100M

Explanation:

A zero-order reaction follows the equation:

[A] = [A]₀ - kt

<em>Where [A] is actual reaction of the reactant = 0.100M</em>

<em>[A]₀ the initial concentration = 0.537M</em>

<em>k is rate constant = 0.075Ms⁻¹</em>

<em>And t is time it takes:</em>

<em />

0.100M = 0.537M -0.075Ms⁻¹t

-0.437M = -0.075Ms⁻¹t

5.83s = t

It takes 5.83s to decrease the concentration of the reactant from 0.537M to 0.100M
