Answer:
33atoms
Explanation:
An atom is the smallest particle that can take part in a chemical reaction.
The given compound is:
3(NH₄)₂S
Here we have 3 moles of (NH₄)₂S ;
So:
Total number of atoms:
2 atoms of N
2 x 4 atoms of H
1 atom of S
Total = 2 + 8 + 1 = 11 atoms
So;
The total atom = 3 x 11 = 33atoms
Answer:
See explanation
Explanation:
The third element in the first transition series is Vanadium
The fourth element in the first transition series is chromium
Given that we have four d orbitals in universe L instead of five as we have on earth;
The electronic configuration of Vanadium in universe L is;
Ar 3d3 4s2
The electronic configuration of chromium in universe L is;
[Ar] 3d4 4s2
Answer:
Here's what I get
Explanation:
ΔE = q + w
The compression cycle is so fast that heat doesn't have time to enter or leave the cylinder.
Thus, q is constant.
When you compress the gas, you are doing work on it and increasing the internal energy (mostly kinetic) of its molecules.
Temperature is a measure of the average kinetic energy of the molecules, so the temperature rises during compression.

Answer:
<h2>The answer is 2.52 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of object = 15.9 g
volume = final volume of water - initial volume of water
volume = 56.3 - 50 = 6.3 mL
It's density is
We have the final answer as
<h3>2.52 g/mL</h3>
Hope this helps you
