Ammonium chloride is salt, and when we add solid salt into water, it’s dissolved and nothing happens. The only thing happens when any salt dissolved in water, is becoming its ions and improve its conductivity.
NH4Cl(s) + H2O(l) → NH4+(aq) + Cl-(aq) + H2O(l)
Blue Mount Alkaline RO Water purifier is India’s first Alkaline RO water purifier with LED display and is a leading brand as it has a wide range of water purifiers that help you to drink healthy and safe water which can help you to boost your health and make you more healthy and fit. The water purifiers remove the acid components from the water and make the water more pure and safe to drink. So, switch your drinking habits to Alkaline Water.
Option a. electronegativity
the measure of the ability of the specified atom to attract electrons in a molecule
Answer:
Exothermic Reactions.
Explanation:
Reactions that release energy are called exothermic reactions.
Whereas that absorb energy are called Endothermic reactions.
More energy is being released to the surroundings than was absorbed to initiate and maintain the reaction in case of exothermic reactions.
Burning of a candle is an exothermic reaction.
Answer:
I'm not 100% sure but I think it is b I'm not great with math tho
1. 100 C
2. Point B to C is the ices heat capacity
3. During the points D to E the bonds of the water molecules build up enough kinetic energy to break their intermolecular bonds (not intra), which can lead to gas.
4. Between points D and E the energy is being released the energy required is equivalent along the line.
5. Between point E and D the water is converting to water (condensation)
6. Energy is being released 2260 j/g
7. Yes, but only under extreme volumetric pressures
8. D and E or B and C
9. Freezing (the water is also becoming less dense)
10. Melting or if water already, absorbtion of energy
11. released.
