Answer:
True
Explanation:
Partial charge is due to difference in electron negativity between two atoms in a molecule. Electrons are attracted towards the atoms with more electro-negativity. In water molecule oxygen has more electro-negativity as compared to oxygen so it is more attracted towards oxygen and thus there is partial charge on it.
Answer:
The correct answer is: 3
Explanation:
Carbocation, also known as a cationic carbon, is a chemical species in which the carbon atom forms <u>three covalent bonds</u> and has a formal charge of +1. It is an unstable species.
A carbocation in which the cationic carbon is bonded to three hydrogen atoms, is called a methyl carbocation. Carbocations in which the carbon atom is bonded to one carbon group, two carbon groups and three carbon groups is called primary, secondary and tertiary carbocation respectively.
Answer:
Cooling lowers the rate of the chemical reaction in the batteries.
Explanation:
When a battery is not in use and it may undergo some chemical changes which leads to decrease in its life (shelf life).
For example in case of Zinc battery, the zinc undergoes reaction with ammonia which deteriorate the cell or battery.
Now if we keep the battery in a cool place like refrigerator, the rate of chemical reaction will decrease (the rate of reaction generally decreases with decrease in temperature). Thus the battery stay fresh longer.
Answer:
Electroplating is the process that uses electric current to reduce dissolved metal ions by the use of electrolysis, to obtain the dissolved metal ions at the other electrode, mostly in the format of a uniform coating.
