Which property or properties can change when the pressure of a gas changes?

Answers

Answer 1

Answer: This law states that the volume and temperature of a gas have a direct relationship: As temperature increases, volume increases, when pressure is held constant. Heating a gas increases the kinetic energy of the particles, causing the gas to expand

Explanation:

Answer 2

According to this law, a gas's volume and temperature are directly correlated: When pressure is held constant, volume rises as temperature rises. The kinetic energy of the particles in a gas increases when it is heated, which causes the gas to expand.

What rules apply to gases?

According to Boyle's Law, when the temperature and mass are both constant, the volume of a given volume of gas sustained at a constant temperature varies inversely with the applied pressure.

The quantity of gas particles, the volume of the container, and the temperature of the gas all affect the pressure of a gas that is confined. The pressure will rise as the amount of gas particles in a container increases. The pressure will rise as a container's volume increases.

Which of these are an atom's valence electrons?​

Answers

Answer:

The Outer-most Electron shell contains the valence electrons.

Bonus Info:

Valence Electrons are used by atoms to make ionic bonds.

Answer:

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴.

D. resist any change in movement.

Answers

C I think maybe I aM right or 1

Since the rightward force is greater than the leftward force by a magnitude of 10 Newton, the ball will: A. move to the left.

Given the following data:

Upward force = 50 Newton.Downward force = 50 Newton.Rightward force = 30 Newton.Leftward force = 40 Newton.

A net force can be defined as the vector sum of all the forces acting on an object.

Hence, net force is the sum of all forces acting simultaneously on an object.

To determine the direction in which the ball would move if the four forces shown are applied at the same time:

For the downward and upward force:

[tex]Net\;force = 50-50\\\\Net\;force = 0\;Newton[/tex]

For the rightward and leftward force:

[tex]Net\;force = 40-30\\\\Net\;force = 10\;Newton[/tex]

Since the rightward force is greater than the leftward force by a magnitude of 10 Newton, the ball will move to the left.

How many molecules of H2O are in 8.54 moles of H2O?
Select one:
a. 5.14 * 10^24 molecules H2O
b. 2.86 * 10^23 molecules H2O
c. 6.02 * 10^23 molecules H2O
d. 5.14 * 10^23 molecules H2O

Answers

Answer:

[tex]\boxed {\boxed {\sf A. \ About \ 5.14 *10^{24} \ molecules \ H_2O}}[/tex]

Explanation:

To convert from moles to units, we must use Avogadro's Number: 6.022 * 10²³

This tells us the number of units (molecules of water in this problem) in 1 mole of a substance (water). We can use it as a ratio or fraction.

[tex]\frac{6.022 *10^{23} \ molecules \ H_2O}{1 \ mol \ H_2 O}[/tex]

Now, we can multiply this fraction by the moles of water (8.54) given.

[tex]8.54 \ mol \ H_2O*\frac{6.022 *10^{23}\ molecules \ H_2O}{1 \ mol \ H_2 O}[/tex]

When we multiply, the moles of water will cancel out.

[tex]8.54 *\frac{6.022 \ molecules \ H_2O}{1 \ }[/tex]

Since the fraction has a 1 as a denominator, we can remove it. The problem will be a simple multiplication problem.

[tex]8.54*6.022 \ molecules \ H_2O[/tex]

[tex]5.142788*10^{24} \ molecules \ H_2O[/tex]

The original measurement of 8.54 has 3 significant figures (8, 5, and 4). Therefore, we must round our answer to 3 sig figs, which is the hundredth place in this case.

The 2 in the thousandth place tells us to leave the 4 in the hundredth place.

[tex]5.14 *10^{24} \ molecules \ H_2 O[/tex]

There are about 5.14*10²⁴ molecules of water in 8.54 moles.

Answer:

5.14 x 10^24 molecules of H2O.

D can be used for your answer

State​ physical property can be used to distinguish between a 1 cm cube of copper and a 1 cm cube of sugar. Hence, option D is correct.

What is physical property?

A property (such as colour, hardness, boiling point) of the matter is not involved in its manifestation of a chemical change.

Physical properties are those general properties you notice most readily about a substance, such as its size, state of matter (solid, liquid, or gas), colour, mass, density and strength.

Values for physical properties can be determined by tests that don't alter the substance being tested.

Hence, state​ physical property can be used to distinguish between a 1 cm cube of copper and a 1 cm cube of sugar.
