I think the best example of rotational motion is :
The wheel spins as long as the hamster keeps running
Rotational motion refer to a rotation movement in which the main axis point stays the same
hope this helps

The answer is 2 pairs. The carbon atom has 4 electrons and oxygen atom has 6 electrons. The purpose of shared electron is to get 8 electrons at the outer layer. So the carbon atom needs to share 4 electrons which is 2 pairs with oxygen to be stable.
Since it has 4 electrons, it needs only 4 more to be stable. Therefore, it would share electrons, which is a covalent bond.
Answer: Covalent bond
Answer:
There is one nitrate ion in the products, and two in the reactants of this equation.
Explanation:
1: We know a nitrate ion has the formula 
, so we just need to count how many of them are on each side of the equation.
2: To find how many are in the reactants of the equation, you look at the left hand side (before the arrow). You can see the section 
, which shows that there are two nitrate ions in the reactant side (as seen by the little 2).
3: To find how many are on the products side, you do the same thing - this time there is only one in the lithium nitrate.
So, there is one nitrate ion in the products, and two in the reactants of this equation.
