Because they have scaled feet
Answer: The answers are the first and third options.
Answer:
60g of LiNO3 are required
Explanation:
<em>Calculate the amount of solute, in grams or milliliters, to prepare...</em>
<em />
The percentage mass/volume %(m/v) is defined as the mass in grams of the solute in 100mL of solution
To solve this question we must know that in a 37.5% (m/v) of LiNO3 you have 37.5g of LiNO3 in 100mL of solution.
Thus, to prepare 160mL are required:
160mL * (37.5g / 100mL) =
<h3>60g of LiNO3 are required</h3>
I don’t understand the question sorry
Answer:
The molecules or ions in a solution can freely intermingle.
Explanation:
The reactant molecules and ions can move freely in solution, so thy are more likely to collide with each other and form products.
A is wrong. Solutions are homogeneous.
B and C are wrong. The statements are correct, but they are not the reason why reactions are carried out in solution.
D is wrong. Chemical reactions do not always produce a colour change.
F is wrong. Some chemicals react with water, so other (often flammable) solvents must be used.
