Answer:
Antibiotic resistance happens when the germs no longer respond to the antibiotics designed to kill them. That means the germs are not killed and continue to grow. It does not mean our body is resistant to antibiotics.
Answer:
Vitamins are classified as either fat soluble (vitamins A, D, E and K) or water soluble (vitamins B and C). This difference between the two groups is very important. It determines how each vitamin acts within the body.
% m/v of the solution = 0.2%m/v

or
% m/v = g solute / 100 ml solution
Concentration : 2 g sodium borate / L water
For 10 L⇒20 g Sodium borate
<u>Answer:</u> The standard change in Gibbs free energy for the given reaction is 4.33 kJ/mol
<u>Explanation:</u>
For the given chemical equation:
The expression of for the given reaction:
We are given:
Putting values in above equation, we get:
To calculate the standard Gibbs free energy, we use the relation:
where,
= standard Gibbs free energy
R = Gas constant =
T = temperature =
= equilibrium constant in terms of partial pressure = 0.174
Putting values in above equation, we get:
Hence, the standard change in Gibbs free energy for the given reaction is 4.33 kJ/mol
The weight of the container after the wax hardens is 0.18 N.
<h3>What is the law of conservation of mass?</h3>
We know that according to the law of the conservation of mass, the mass of an object can neither be created nor destroyed but it can be changed from one form to the other.
Looking at this law, we know that the mass would not change even after the time that the wax must have hardened. The total mass of the wax would have to be a constant.
Total mass would now be;
Mass of the wax + mass of the container
= 3 g + 15 g
= 18 g
Weight = 18/1000 * 9.8 m/s^2
= 0.18 N
