For A:
Your longest carbon chain is 5 so it's overall a pentane
you have 2 branchings on Carbon 2 and 4; and the branchings are methyl groups
so the name would be 2,3-dimethylpentane
Give me a little on B: It's giving me some trouble
A. Cesium because reactivity of alkali metals increases from the top to the bottom of the group.

Answer:
Activation Energy
Explanation:
The main cause of slowness to start a reaction is the value of it activation energy. When metals possess low activation energy, it takes them time to start a reaction. But once started, the reaction becomes vigorous.
Activation Energy: the minimum quantity of energy which the reacting species must possess in order to undergo a specified reaction.
Answer:
Q 3 = lightning
Q 4 = False because there is also a fourth state of matter which is called plasma.
Q 5 = most of the matter in universe is made up of plasma.
Explanation:
Plasma:
" The ionized gaseous mixture consist of atoms, ions and electrons is called plasma"
The plasma was first time identified by William Crookes in 1879. More than 99% universe matter is consist of plasma.
It is the fourth state of matter, the other three are solid, gas and liquid. The most of matter in the universe is plasma. When heat is supplied to the atoms, they gain energy the electrons in atom thus escape from the atom by gaining the energy and create the positive charge. Thus ions are formed. When heat is constantly supplied, the ionization process continue to take place and produce large number of positive charges, free electrons but some atoms not get ionized and remain neutral. Thus a cloud of free electrons , positive charge and neutral atoms is formed which is called plasma.
Examples:
The shining stars, lightning bolts, fluorescent light, flames, electrical current which passes through neon gas are some examples of plasma.
