A neutron has neither a negative or positive charge, it’s neutral
Answer:
0.9359 M
Explanation:
M(CaCO3)=100.1 g/mol
10.305 g * 1 mol/100.1 g = 10.305/100.1 mol CaCO3
(10.305/100.1 mol )/0.1100 L = 0.936 mol/L = 0.9359 M
<u>Answer:</u> The new pressure of CO is 0.09 atm
<u>Explanation:</u>
For the given chemical reaction:

The expression of
for above equation follows:
.......(1)
We are given:

Putting values in above equation, we get:

Addition pressure of chlorine added = 0.39 atm
Now, the equilibrium is re-established:

Initial: 0.26 0.15 0.66
At eqllm: 0.26-x 0.54 0.66+x
Putting values in expression 1, we get:

So, new pressure of CO = 0.26 - x = (0.26 - 0.17) = 0.09 atm
Hence, the new pressure of CO is 0.09 atm
Answer: Option (C) is the correct answer.
Explanation:
The degree of randomness or disorder is known as entropy. This means that more randomly or rapidly the molecules of a substance are moving in a container or in the Universe more will be its entropy.
For example, gases move more rapidly that solids or liquids and hence gases have high entropy.
Therefore, we can conclude that entropy measures disorder.
The number of Valence electrons are the same number as the group the element is in. For example Carbon is in group 4 and has 4 Valence electrons.
