Which state of the West produces the widest varieties of fruits, vegetables, and nuts?

Suppose an object is moving through space in a straight line. What could cause the object to start moving in a circle?

MAVERICK [17]

It could pass by a large enough object that has enough gravity to pull the object into its orbit and the object would stay in orbit because it has centripetal force.

What volume (in mL) of 0.250 M HCI would be

Nitella [24]

Answer: 1820 mL (to 3 sf)

Explanation:

The atomic mass of aluminum is 26.9815385 g/mol, so 4.10 g of aluminum is equal to 4.10/26.9815385 = 0.15195575300497 moles of Al.

From the coefficients of the equation, we know that for every 2 moles of aluminum consumed, 6 moles of HCl are consumed.

So, this means we need 0.15195575300497(6/2) = 0.45586725901491 moles of HCl.

Substituting into the molarity formula,

0.250 = 0.45586725901491/(liters of HCl)
liters of HCl = 0.45586725901491/0.250
liters of HCl = 1.8234690360596 L = 1820 mL (to 3 sf)

Indicate the changes (increases, decreases, does not change) in its volume when the pressure undergoes the following changes at

Inga [223]

The question is missing information. Here is the complete question.

A gas at a pressure of 2.0 atm is in a closed container. Indicate the changes (if any) in its volume when the pressure undergoes the following changes at constant temperature and constant amount of gas. Match the words in the left with the column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer.

1. The pressure increases to 6.0 atm. The volume ________

2. The pressure drops to 0.40 atm. The volume _________

3. The pressure remains at 2.0 atm. The volume _________

Answer: 1. Decreases

2. Increases

3. Does not change

Explanation: According to the Ideal Gas Law, Pressure, Volume and Temperature of an ideal gas is related, as the following: PV = nRT.

In this case, since temperature (T) and amount of gas (n) are constant, the Boyle's Law can be used.

The law states that the volume of a given gas, under the conditios of temperature and amount of it are constant, is inversely proportional to the applied pressure: P₁.V₁ = P₂.V₂

For case 1.)

Initial P (P₁) = 2

Initial V (V₁) = V

Final P (P₂) = 6

P₁.V₁ = P₂.V₂

2.V = 6.V₂

V₂ = 1/3V

When the pressure increases to 6 atm, volume decreases by 1/3.

For case 2.)

P₁ = 2

V₁ = V

P₂ = 0.4

2.V = 0.4V₂

V₂ = 5V

When pressure drops to 0.4 atm, volume increases by 5.

For case 3.)

Since there are no change in the pressure, the volume is the same from the beginning, so does not change.

What's the constant presuure of gas?

pickupchik [31]

Answer:

Constant pressure of gas must have a constant volume and a constant number of moles of gas. It's equation is the ideal gas law: pV=nRT

Explanation:

The gas state is the most excited state. It doesn't have a definite volume or shape which is why it can be compressed. Gas pressure is basically the result of all the gas particles moving around and colliding against each other and their container. The rate this happens at as well as its force determines the pressure. Since there are many, many of these gas particles in all quantities of gas, the fluctuation of this rate as well as its intesity is nearly constant.
