# A particular brand of gasoline has a density of 0.737 g/ml at 25 ∘c. how many grams of this gasoline would fill a 14.1 gal tank?

Answer: Density is defined as the mass per unit volume,
mass of the solution is therefore
mass = density x volume
1 gal = 3785.41 mL
therefore 14.1 gal = 3785.41 x 14.1 = 53 374.3 mL
mass of gasoline required = 0.737 g/mL x 53 374.3 mL
mass of gasoline required to fill the tank - 39 337 g = 39.3 kg
39.3 kg of gasoline is required

Is rain turning to snow a physical or chemical change?

Hello There!

Physical changes can be reversed whereas chemical changes can not.
Rain turning to snow is a physical change.
The snow could certainly be changed back into rain.
An example of a chemical change is making toast.
Once the toast is made, it is not possible to reverse.

In short, it is a physical change.

In order to form methane, one carbon atom shares electrons with four hydrogen atoms. Which of these best describes why methane would form in nature? A)
The ionic bonds formed help to stabilize the molecule.
B)
The atoms become less stable by sharing electrons.
C)
The covalent bonds formed help make each atom more stable.
Eliminate
D)
Methane is only formed in a lab and cannot be made naturally.

Its actually C btw.

A)
The ionic bonds formed help to stabilize the molecule.

Can nonsmokers hold their breath longer than people who smoke? Write the independent variable, the dependent variable, and the hypothesis.

Independent variable (what you are changing): smoker vs nonsmoker
Dependent variable (what you are measuring): how long breath can be held

Hypothesis: If both smokers and nonsmokers hold their breath, then the nonsmokers will be able to hold their breath for longer.

Could a mixture be made up of only elements and no compounds?

Yes, a mixture could be made up of only elements and no compounds, given that the elements never undergo a chemical interaction and stay only in physical contact with each other.

A compound is a substance bond between two or more different atoms, giving it a molecule. Substances within a composite can be really separated from each other as they nevermore respond chemically with one another. A mixture can have a mix of elements and mixtures or just a series of one or the other. So yes a mixture be made up of only elements and no compounds.

What is the VESPR model used for

VESPR (Valence Shell Electron Pair Repulsion) is used to determine the shape of the molecules based on their number of electron pairs and how they interact with each other via repulsion. Different numver of electron pairs will form different shapes, e.g. 0 pairs = linear, 1 = pyramidal...
Its used to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms.

According to Dalton's atomic theory, which of the following best describes an atom? Can be destroyed
Present in all matter
Composed of elements
Does not contain particles

Present in all matter

Explanation:

John Dalton was the first scientist to propose the 'theory of atom'. The crucial ideas of Dalton's theory were:

- All matter is composed of atoms

- Atoms are indivisible

- Different atoms combine to form molecules

- Atoms of the same element have identical mass, size and properties

Thus, based on the given options the statement that best describes an atom from the perspective of Dalton's theory is that they are present in all matter

Present in all matter.
