Answer:
Maximum amount of ethanol - 483g, 0.612L.
Answer:
65 mg
Explanation:
We are given the dosage per pound but have the weight of the dog in kilograms, thus we should convert the 29.5 kg to punds ( 1 pound = 0.454 kg):
29.5 kg x 1 lb / 0.454 kg = 64.7 lbs
So now can answer our question:
( 1 mg / lb ) x 64.7 lb = 64.7
rounding to 65 mg
To treat itchy skin in a dog that weighs 29.5 kg, the dog should be given 65 mg of Benadryl.
To calculate the mass of Benadryl to give to a dog that weighs 29.5 kg, we need to use the recommended dosage of 1 mg per pound. First, we convert the weight of the dog from kg to pounds by multiplying it by 2.2046. So, the weight of the dog is approximately 65 pounds. To find the mass of Benadryl, we multiply the weight of the dog in pounds by the recommended dosage. Therefore, the dog should be given 65 mg of Benadryl.

b.unsaturated.
c.saturated.
d.supersaturated.
Answer:
d. supersaturated.
Explanation:
A solution naturally contains a solute and a solvent. The solute is the solid substance that dissolves in the solvent, which is usually a liquid substance. A solution has a maximum amount of solute that can dissolve in its constituent solvent.
However, when the amount of dissolved solute in a solution at a given temperature is greater than the amount that can permanently remain in the solution at that temperature, the solution is said to be SUPERSATURATED. This means that the solution contains more than the maximum amount of solute.
Answer:
7.97 mol Ar
Explanation:
Use Avogadro's number to convert atoms to moles. This number is the number of atoms in one mole. There are 6.022 × 10²³ atoms in one mole.
Divide the number of atoms given by Avogadro's number.
(4.80 × 10²⁴)/(6.022 × 10²³) = 7.97 mol
There are 7.97 moles of argon.
Answer:
3.0 moles (A P E X)

Answer :
Sugar : Compound
Air : Homogeneous mixture
Hot tea : Homogeneous mixture
Salt water : Homogeneous mixture
Explanation :
Element : It is a pure substance which is composed of atoms of similar elements.
Compound : It is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.
Heterogeneous mixtures : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different.
There is a physical boundary between the dispersed phase and dispersion medium.
Homogeneous mixtures : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different.
There is no physical boundary between the dispersed phase and dispersion medium.
As per question,
Sugar : It is a compound that is made from atoms of different elements combined together in a fixed ratio by mass.
Air : It is a homogeneous mixture of the gaseous substances of nitrogen, oxygen, and smaller amounts of other substances.
Hot tea : It is a homogeneous mixture because its composition is the same throughout the solution.
Salt water : It is a homogeneous mixture because its composition is the same throughout the solution.
Sugar compound
Air Homogeneous mixture
Hot tea Homogeneous mixture
Salt water Homogeneous mixture
Element:
An element is a simplest type of a pure substance which is composed of only one type of matter. For examples; silver, gold platinum etc.
Pure substance:
A compound is a pure substance which is composed of two or more type of matter in definite proportion. For examples; water which is composed by Hydrogen and oxygen etc.
Mixture:
A mixture is made from two or more type of matter in any proportion. Mixture are generally two types:
1. Homogeneous mixture
This is also known as solution, in which the composition of the substances is uniform.
Lemon-flavored water is an example of homogeneous mixture because in this the composition of the substances is uniform.
2. Heterogeneous mixture
In this form of mixture the composition of substance are not uniform and the component of mixture also visible.
Stuffed mushrooms is an example of Heterogeneous mixture because in this form of mixture the composition of substance are not uniform and the component of mixture also visible.
Explanation:
Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called a saturated solution.
