I believe it means put the correct animal in the right category. Like for producer you would put the plant for herbivores you would put the type of insect that they are showing that eats the plant. I think that is what they are wanting you to do.
<span>According to the Graham's law, effusion rate is inversely proportional to the molecular weight. It means that the gas with the lowest molecular weight will have the highest effusion rate.
The moleclar weights of these gases are as follows:
Ar = 40 gm/mol
C_3H_8 = 3</span>x12+8= 44 gm/mol
He = 4 gm/mol
So, the order according to decreasing rate of effusion will be:
1. He
2. Ar
3. C_3H_8
Answer:
1
Explanation:
Hyaluronidase is an enzyme that is naturally found in the body that breaks down hyaluronic acid. Hyaluronic acid is considered the glue that holds cells together.
The correct answer is option A, that is, the mass of the solute.
Before, preparing the solution, the laboratory technician needs to measure the mass of the solute. In the given question, the molarity of NaOH is given, the volume of the solution is given, the molar mass of NaOH is 40 g/mol.
As one knows the molarity of the solute, the volume of the solution, and the molar mass of the solute, thus, there is a need to determine only the mass of the solute prior of preparing the solution.
The more acid the salt, the lower the pH. So we must find the salt that is most basic among the options. Our answer is
, because it is formed by a weak acid (
) with a strong base (
).
