Answer:
Hi
Sodium Hydroxide is a strong base, it dissolves easily in water producing a large amount of calories and completely dissolving in its ions, to give hydroxide ions, as seen in the reaction:
NaOH(ac) ⇒ Na+(ac) + OH-(ac)
In the presence of ambient humidity, sodium hydroxide reacts with carbon dioxide to generate sodium carbonate. The gradual hydration generates six different hydrates: NaOH.H2O, NaOH.2H2O, NaOH.3.5H2O, NaOH.4H2O, NaOH.5H2O, NaOH.7H2O. Its great affinity for water causes a reduction in water vapor pressure and for that reason it is a very good drying agent.
Explanation:
The subscript 3 outside of the parentheses means to multiply everything in the parentheses by 3, so it becomes a matter of addition:
3*(CH3) * (1 carbon atom)/(CH3) = 3 carbon atoms in (CH3)3
CH has one carbon atom and one hydrogen atom, so:
1 carbon atom in CH
Add both of them together, and you get 4 carbon atoms in isobutane
Answer:
Dipole-dipole forces
Explanation:
A polar compound is that compound which contains atoms that have a difference in charges i.e electrostatic attraction occurs between its constituent atoms. Polar molecules are attracted to other polar molecules with opposite charges and her held together with the aid of certain forces
The attractive force between the negative part of a polar molecule (-) and the positive part of another polar molecule (+) is called DIPOLE-DIPOLE FORCES. This dipole-dipole force gets stronger with an increasing polarity of the molecules involved.
Answer:
TRUE
Explanation:
An Equipment grounding conductor are used to ground a non current-carrying metallic parts of any equipment. Its main function is to keep the equipment close to the ground potential as possible and is also allows a safer path for the ground-fault current to flow. If the equipment is grounded, all the excess current will go to the ground and will not damage the equipment.
Hence the answer is TRUE.
