Answer:
organic
Explanation:
Organic substances are those which contains covalently linked carbon to hydrogen (C-H) bonds in their structure. In other words, organic compounds or substances are uniquely composed of carbon and hydrogen atoms covalently linked together.
These substances usually contain a long chain of these bonds, hence, making them complex. Therefore, according to this question, substanves that are complex molecules and contain carbon atoms bonded to hydrogen atoms are referred to as ORGANIC SUBSTANCES.
Answer:
No it is not a good conductor
Explanation:
Krypton is classified as a gas and nonmetal. Like many nonmetals and gases, krypton is an insulator, so it is a relatively poor conductor of heat and electricity.
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.
