Na is a metal
N is a nonmetal
thus, they form an ionic bond, where electrons are transferred from the metal, to the nonmetal
Answer:The units of molarity are M or mol/L. A 1 M solution is said to be “one molar.”
Explanation:
An atom having 52 protons and 54 electrons would have an atomic number of 52 and a net charge of -2. This element would be 52 Te 2-, or choice A.
Answer:
Potential energy can be defined as the energy in a body due to its position
In simple terms potential energy is the energy at rest
Explanation: Examples ;
- A spring has more potential energy when it is compressed or stretched.
- A steel ball has more potential energy raised above the ground than it has after falling to Earth.
The answer is (2) 0.2. The unit of M means 1 mol/L. The conversion of liter and milliliter is 1 liter equals 1000 milliliters. So the molar number of solute is 1*0.2=0.2 mol.
