Answer:
Electro negativity and polarity of the bond in the both molecules
Explanation:
Approaching the matter from an electro negativity perspective, oxygen is more electronegative than sulphur. This implies that the O-H bind is more polar than the S-H bond.
The high polarity of the O-H bond leads to a higher degree of hydrogen bonding in H2O than in H2S. This higher degree of hydrogen bonding in H2O leads to greater intermolecular association and the substance is a liquid. Hence H2O is liquid but H2S is a gas.

The electrolysis describe " electrical energy is used to produce a chemical change."
The process of dissolving ionic compounds into various constituent components by running a continuous electric current through into the complex in a fluid form is known as electrolysis.
The energy produced by the flow of electrons from one location to another is referred to as electrical energy. Current or electricity is the transportation of charged particles across a medium.

The plausible reason for the change in mineral A will be the lower activation energy than the transferred energy.
The addition of energy will result in the change in the minerals if the activation energy is exceeded.
The minerals found in mining A and B have transferred the energy. The minimum amount of energy required to do the transition in the atoms in the activation energy.
The possible reason for the change in the mineral A will be the lower activation energy for the mineral A. The mineral B does not change because the activation energy of mineral B is higher as compared to mineral A.
For more information, refer to the link:
Answer: Mineral A changed because Molecular energy transferred is equal or greater than than its Activation energy
Mineral B didn't change because Molecular energy transferred is less than its Activation energy.
Explanation:
The molecules of Mineral A has been disturbed by the addition of energy causing a change and the entropy is increased. The Molecules of Mineral B has not been disturbed because the residual energy has not been overcome and therefore yielding no visible change
To produce 100.0 L of NH3 at STP, 62.4 grams of N2 are required.
The balanced equation for the reaction is:
N2(g) + 3H2(g) → 2NH3(g)
According to the balanced equation, one mole of N2 reacts with three moles of H2 to produce two moles of NH3. From this information, we can use stoichiometry to determine the mass of N2 required to produce 100.0 L of NH3 at STP.
First, we need to convert liters of NH3 to moles using the ideal gas law and the molar volume of a gas at STP (~22.4 L/mol). Once we have the moles of NH3, we can use the mole ratio from the balanced equation to calculate the moles of N2. Finally, we can use the molar mass of N2 to convert moles to grams.
Let's calculate:
Therefore, 62.4 grams of N2 are required to produce 100.0 liters of NH3 at STP.

a strong acid and a weak acid.
a strong base and a weak base.
an acid and water.
The right answer is A (strong acid with strong base).
The reaction of an acid with a base to produce salt and water alone is called a neutralization reaction.
A salt is a compound formed following a replacement of the hydrogen ions (H +) of an acid with a basic radical during a reaction.
A normal salt is formed by the complete replacement of the H + of an acid (example Na2CO3).
while an acidic salt is formed by the incomplete replacement of the H + of an acid (eg NaHCO3).
