Answer:
A) An ionic compound dissolved in a polar solvent
Explanation:
Potassium Chloride's chemical formula is KCl. Most ionic compounds are formed between a nonmetal and a metal. In this case, potassium is acting as the metal and chloride is the nonmetal. Water is a polar solvent due to the electronegativity of the oxygen in the molecule creating a partial negative pole, leaving the hydrogen atoms partially positive. Hence, A is your best answer.
If I helped, a brainliest would be greatly appreciated!
Answer: The amount of energy needed to move an electron from one zone to another is a fixed, finite amount. The electron with its extra packet of energy becomes excited, and promptly moves out of its lower energy level and takes up a position in a higher energy level.
Explanation:
An object on the moon is 1/6 of the weight of an object on Earth
To find the answer to your question, divide the number of N on Earth by 6, 6N / 6 = 1N
Hope this helps!
Answer:
a. neutron
Explanation:
A neutral atom has the same number of protons and electrons because in order for it to be a neutral atom the charges must be the same.
a neutron has no charge therefore it can be different then the number of protons and electrons in a neutral atom as it won't affect the charge.
