Answer:
Explanation:
1. Force between two charged ions: Electrical force
Electrical force of attraction exists between two charged ions due to constant flow of electrons occuring within their field of influence.
2. Ion made of two or more atoms of different elements
: Polyatomic ion
A polyatomic ion is made up of two or more different elements. Most radicals forms polyatomic ion e.g SO₄²⁻
3. Compound whose atoms form bonds by transferring electrons
: Ionic compound
Ionic compounds forms by the transfer of electrons from a less electronegativbe atom to a more electronegative one. This is in a bid for the atoms to achieve stability.
4. Smooth solid formed by repeating patterns of ions, atoms, or molecules
: Crystal
A crystal is a unit of an atom which is made up of definite repeating patterns over a long range.
5. Chemical bond formed when electrons are transferred: Ionic bonds
The bonds resulting from the transfer of electrons between two atoms is an ionic bond. An example is that between Na⁺ ions and Cl⁻ ioin in NaCl

Answer: 6 moles
Take a look at the balanced chemical equation for this synthesis reaction
N 2(g] + 3 H 2(g] → 2 NH 3(g]
Notice that you have a 1:3 mole ratio between nitrogen gas and hydrogen gas. This means that, regardless of how many moles of nitrogen gas you have, the reaction will always consume twice as many moles of hydrogen gas.
So, if you have 2 moles of nitrogen taking part in the reaction, you will need
2 moles N 2 ⋅ 3 moles H 2 /1 mole N 2 = 6 moles H 2
This problem is providing the mass, energy, initial temperature and specific heat of a sample of copper that is required to calculate the final temperature.
Thus, we recall the general heat equation:
Which has to be solved for the final temperature, 
as follows:
Finally, we plug in the numbers to obtain:
However, this result is not given in the choices.

Answer:
Dispersion Forces are found between n-Pentane (CH₃-CH₂-CH₂-CH₂-CH₃) and n-Hexane (CH₃-CH₂-CH₂-CH₂-CH₂-CH₃).
Explanation:
Dispersion Forces are present and developed by those compounds which are non-polar in nature. In given statement n-Pentane and n-Hexane both are non-polar in nature as the electronegativity difference between Hydrogen atoms and Carbon atoms is less than 0.4.
When non-polar molecules approaches each other, a Dipole is induced in one of them, this step is known as Instantaneous Dipole, This generated Dipole on approaching another non-polar molecule induces dipole in it and the process propagates. Hence, creating intermolecular interactions.
