Answer:
Volume = 10ml
Density = 1/5 g/ml or 0.20g/ml
Explanation:
The rocks are 10ml since the initial volume went up by 10.
Since density = mass/volume, you divide 2 by 10.
D = 2/10
D = 1/5 g/ml or 0.20g/ml
(Unit is g/ml aka grams/millileter)
Answer: Option (b) is the correct answer.
Explanation:
Vitamins which are soluble in water are known as water-soluble vitamins. And, vitamins which remain insoluble in water are known as water-insoluble vitamins.
Water-soluble vitamins are able to be easily excreted by the human body through urine. For example, vitamin C and vitamin B-complex are water soluble vitamins.
Thus, we can conclude that water-soluble vitamins are easily excreted in the urine.
Answer: The products formed in this Bronsted-Lowry reaction are
and
.
Explanation:
According to Bronsted-Lowry, acids are the species which donate hydrogen ions to another specie in a chemical reaction.
Bases are the species which accept a hydrogen ion upon chemical reaction.
For example, 
Here, the products formed in this Bronsted-Lowry reaction are
and
.
Thus, we can conclude that the products formed in this Bronsted-Lowry reaction are
and
.
Answer:
Explanation: This reaction is called a synthesis reaction. This is because a synthesis reaction is when two or more reactants combine/react together to form a single product. The two reactants carbon (C) and oxygen (O2) reacted together to form one single product: carbon dioxide (CO2)
Number D both H and OH ions
