According to Le Chatelier’s principle, if the dynamic equilibrium of a system is disturbed by any change in the conditions of the system then the equilibrium will adjust itself in such a way that new equilibrium moves to counteract the change.
Hence, when the concentration of reactants is doubled in a chemical reaction that was in equilibrium then the equilibrium shifts to the right to favor the formation of products.
Answer: Option (d) is the correct answer.
Explanation:
Atomic number of carbon is 6 and its electronic distribution is 2, 4. Therefore, in order to become stable and completely fill its octet carbon readily share its valence electrons with another atom.
For example, 
A carbon atom is also able to form a double double with valence electrons of other atom.
Thus, we can conclude that a carbon atom has a strong tendency to share electrons.
Answer:
1.38x10⁻⁴ M
Explanation:
First, we <u>calculate the pOH of the solution</u>, using the <em>given pH</em>:
Now we <u>calculate the concentration of OH⁻</u>, using<em> the pOH</em>:
- [OH⁻] =
= 2.75x10⁻⁴ M
Following the reaction Ca(OH)₂ → Ca⁺² + 2OH⁻, we divide [OH⁻] by 2 to calculate [Ca(OH)₂]:
- [Ca(OH)₂] = 2.75x10⁻⁴ M / 2
<u>Charge:</u>
An electron has a negative charge and a <em>n</em>eutron has a <em>n</em>eutral charge.
<u>Size:</u>
Electrons have a really small mass whereas the neutron has a mass of about 1 amu.
<u>Location:</u>
Neutrons are found in center of an atom, but electrons are around it.
<u>Number:</u>
The number of electrons and neutrons in atom varies.
