<span>This is the process of radioactive dating. Carbon is used because it is an essential part of all living organisms and has a radioisotope that decays with a half-life of 5000 years. This ratio makes it easy to date an object using Carbon-14. Uranium is used for objects that have a much longer half-life, outside the bounds of carbon's abilities.</span>
Answer:
a
. Shift it to the right toward the products.
Explanation:
In the reaction, if more of the reactant A is added to the system, the reaction will shift towards the products.
- If a system at equilibrium is disturbed by changing the concentration of one of the substances, all the concentration will change until a new equilibrium point is reached.
- If we add more reactants, the concentration is increased and the reaction shifts to the right so as to maintain the constancy of the equilibrium constant.
<h2>Let us complete it :</h2>
Explanation:
In sodium phosphide
Electrons are transferred from atoms of sodium
to atoms of phosphorous .
This transfer makes the sodium atoms to loose electrons
and the phosphorus atoms to gain electrons
As a result, the sodium and phosphorus bond strongly each other with a ionic bond .
The bond formation occurs as shown :
Sodium looses one electron to form Na⁺¹.
Phosphorous gain electrons to form P³⁻.
So, now we have :
Na ⁺ P³⁻
After criss crossing we have :
Na₃P
Any colloid consisting of a solid dispersed in a gas is called a smoke. A liquid dispersed in a gas is referred to as a fog. So the answer would be smoke
The most stable oxide is this francium oxide A) Fr2O
