it's 3 dollars per 12 eggs so 3/12

simplify 3/12 by dividing both numbers by 3 so you get 1/4

you should know what 1/4 of a dollar is

or think of it this way 12 eggs are 3 dollars so every 4 eggs is one dollar. divide 1 dollar by 4 eggs

Answer:

150K is 253.67°F

Explanation:

There is a simple formula to convert from Kelvin to Celsuis;

C° = K - 273.15

Then you would convert Celsuis into Fahrenheit using the formula:

[tex]F = \frac{9}{5}C + 32\\[/tex]

Once the animal eats the food, the atoms in food are  used to make the animal grow.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Answer:

34.9103 or 34.9 g

Explanation:

Remember Density is a broken heart: m/v.

In this scenario (Let x = # of grams in the sample of gasoline),

D = 0.7198 g/mL = x g / 48.5 mL

So,

(0.7198 g/mL) * (48.5 mL) = x g

x g = 34.9103 = 34.9 g (Accounting for Significant Figures)

Molecular structure affects the strength of electrostatic forces, which can affect the boiling point of a substance is the statement that correctly describes the relationship between these terms.

The molecular structure is the way in which the atoms that are in a molecule are arranged in space, this is defined by a series of forces that hold the atoms together in a specific arrangement.

The boiling point is the temperature at which the vapor pressure of the liquid equals the pressure that surrounds the liquid, when this happens, the liquid transforms into gas.

Therefore, we can conclude that the boiling point depends on the molecular mass of the substance and the type of electrostatic forces present, that is, the bonds that the atoms establish with each other to form the molecule (molecular structure).

Answer: at dynamic equilibrium, the rates of forward and reverse reactions are equal.

Explanation:

The correct statement defines dynamic equilibrium "at dynamic equilibrium, the rates of forward and reverse reactions are equal."

The state of a particular system wherein the reversible reaction takes place ceases modifying the ratio of reactants as well as products, but there is still a transfer of substances among the reactants and products is known as dynamic equilibrium.

Chemical reaction can be defined as the a method for creating novel chemicals with unique features.

The correct statement defines dynamic equilibrium "at dynamic equilibrium, the rates of forward and reverse reactions are equal."

Therefore, the correct answer will be option (a).

Answer:

I think 1, 4, and 5 are the answers to this question. I am not sure about 4 though.

Explanation:

You have to have a power source (1), you also have to have a way to get that power somewhere else (5), and the reason for 4 would be that the power has to come back through the power source to remain working.

Answer:

Sr(OH)2

Explanation:

Strontium hydroxide, Sr(OH)2, is a caustic alkali composed of one strontium ion and two hydroxide ions. ... Sr(OH)2 exists in anhydrous, monohydrate, or octahydrate form.

Answer:

The molecular structure affects solubility mainly biased on its polarity or bonded ions.

Explanation:

Polar molecules will better interact with the water molecules and will dissolve easier. Nonpolar molecules can dissolve if they are small enough, however they don't interact well with the polar molecules. Bonded ions, such as NaCl split into a cation Na and an anion Cl which the positive charge on the Na will be attracted to the oxygen, and the negatively charged Cl will be attracted to the positive Hydrogen.

**Remember this rule, like dissolves like, meaning nonpolar dissolves nonpolar and polar dissolves polar.

Answer:

D.

Explanation:

A concentrated solution is one that has a lot of solute (the substance being dissolved) in the solvent (the substance doing the dissolving). When a solution is concentrated, it means it has a high ratio of solute to solvent, so the answer is D.

1st question: A mixture is when the components of a mixture can be easily separated and that the components each keep their original properties.

2nd question:A phase is any part of a sample that has a uniform composition and properties.By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers.

Heterogeneous mixtures are not uniform in composition. Examples would be wood or blood. Homogeneous mixtures are uniform through out. Typically you can see through them.

Answer:

How Does a Solar Panel Generate Power? Solar panels use the photons produced by sunlight to generate direct current (DC) electricity. When the photons hit the panel they are absorbed by the panel's semiconducting silicon material.

Explanation:

Answer:

Solar panels produce electrical energy by absorbing the solar energy from the sun and converting it into electrical energy.
