Answer:
The potential difference is considered as the change in terms of voltage or Del V. It is measured in terms of voltage so that statement got the name voltage change between point A & B is 1. It means that I joule of work is carried out for moving the 1 coulomb of charge from the point A to B.
Answer:
B) 0.025 
Explanation:
Solution of the problem is in picture attached,
Answer:
Since there are 3 Hydrogen atoms present, the formula mass of H is 1.0 × 3 = 3.0 g/mol. Therefore, by adding them up, the formula mass of ammonia is: [14.0 g/mol + 3.0 g/mol] = 17.0 g/mol.

Explanation:
Answer:
D. Solutions are formed when the water’s polar molecules separate the polar molecules of an ionic or molecular compound.
Explanation:
Solutions are homogeneous mixtures formed by interaction between solutes and solvents.
Water based solutions have water as the solvents and mostly ionic and molecular compounds as their solutes.
Water is a polar solvent that is capable of dissolving many compounds by hydrating them. The molecules of water surrounds the solute and forces them to separate.
