Answer/Explanation:
Heat from the sun hits the ground and is absorbed. The higher you go, it gets more colder due to the fact that the air doesn't hold onto the radiation as it goes straight through the ground, which is why the top of mountains are very cold, and people are able to die in minutes.
Answer: -
Fission creates large amounts of radioactive waste.
Explanation: -
During nuclear fission, by products are formed. These by products are radioactive in nature. They give radiation. These radiation causes a lot of harm to humans including cancer and mutations.
Thus, Fission creates large amounts of radioactive waste.
Answer:
Explanation:
Iodine is present in salt which makes it salty:)
Answer:
D.) They often form hydroxide ions.
Explanation:
They generate hydroxide ions in water. they are soapy to touch and bitter in taste. they conduct electricity.
(all bases have hydroxide ions)
(1) O2 Is a Nonelectrolyte: because it does not ionize when dissolved in a solution
(2) Xe Is a Nonelectrolyte: because it does not ionize when dissolved in a solution
(3) C3H8 Is a Nonelectrolyte: because it does not ionize when dissolved in a solution
(4) KNO3 Is an electrolyte: because it ionizes when dissolved in a solution
Electrolytes:
Electrolytes are the substance whose aqueous solution conducts electricity. These are mainly two types:
1. Strong electrolytes
2. Weak electrolytes:
Strong electrolytes:
Strong electrolytes have following properties:
1. They are ionic compounds.
2. They are completely separates into their ions when dissolved in water.
3. In solution form they conduct electricity due to present of ions but in solid form means neutral molecule does not conduct electricity.
Weak electrolytes:
Weak electrolytes are partially ionizes in water.
In general strong electrolytes are strong acid and strong base while weak electrolytes are weak acid and weak bases.
Nonelectrolyte:
The substance which does not ionize when dissolved in a solution is called non-electrolyte. It is a poor conductor of electricity.
