Answer:
A is denser than B as it's volume for the same mass is smaller.
Explanation:
Hello.
In this case, we first need to take into account that the density of each metal A and B is computed by dividing the mass over the volume of each metal which is actually computed by substracting the volume of water from the volume of the water and the solid:
Next, we compute the densities as shown below:
In such a way, A is denser is B as it's volume for the same mass is smaller.
Best regards.
Answers:
1) - COOH
2) carboxyl group
The organic acids contain the carboxyl group: - COOH.
Fats are structures composed by fatty acids. Fatty acids are long aliphatic chains with a carboxyl group at the end.
Aminoacids are chains that contains amine group (NH2) at one end and the carboxyl group at the other end.
Then both aminoacids and fatty acids contain the carboxyl group (-COOH) at one end.
Well there are 1,000 milligrams in 1 gram so 9.815 grams of sugar is equivalent to 9,815 milligrams of sugar. So a bar of milk chocolate contains 9,815 milligrams of sugar.
1) <span>NaNO3 and H2O - no reaction , it is dissolution
2) no hydrogen to make water
3) </span><span>Fe(OH)3 (base) and H2SO4(acid))
base +acid ----> salt +water
4) </span><span>Li2O and Ba(OH)2
basic oxide and base ----> no reaction
so Answer number 3)
</span> 2Fe(OH)3 +3 H2SO4 ------> Fe2(SO4)3 + 6H2O<span>

Rocks are made up deposited minerals that form and condense into rocks
