The volume of a gas at 99.0 kPa is 300.0 mL. If the pressure is increased to 188kPa, what will be the new volume?

Answers

Answer 1

Answer:

Answer:

158.0 mL

Explanation:

We can solve this problem by using Boyle's law, which states that:

"For a fixed mass of a gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"

Mathematically:

$p\propto (1)/(V)$

where

p is the pressure of the gas

V is its volume

The equation can be rewritten as

$p_1 V_1 = p_2 V_2$

where in this problem:

$p_1=99.0 kPa$ is the initial pressure

$V_1=300.0 mL$ is the initial volume

$p_2=188 kPa$ is the final pressure

Solving for V2, we find the final volume:

$V_2=(p_1 V_1)/(p_2)=((99.0)(300.0))/(188)=158.0$ mL

Explain why each mineral has its own properties, different from every other mineral

Answers

Each mineral has its own properties different from other minerals because minerals are made up of different elements. Different elements which can be found on the periodic table all have unique properties, therefore, gold will have distinct properties in comparison with zinc or aluminium for example because they are made up of different elements :))))

Are producers heterotrophs or autotrophs?

Answers

Answer:

Autotrophs

Explanation:

Autotrophs make their own food, or produce food for themselves through the process of photosynthesis. Therefore, we can say that autotrophs are also producers. Some examples of producers are plants, algae, and some types of bacteria.

column 1 Crystalline
column 2 Noncrystalline
column 1. Definite shape
column 2. Definite volume
column 1 Viscous
column 2 Nonviscous

Answers

Answer:

column 1: they are solids that form crystals.

column 2: Are liquid solutions.

Explanation:

Crystals are solids, some of them can have viscosity like glass.

Liquid solutions, are formed by some ions dissolved in water, so they can have a definite volume and could be a liquid that is nonviscous because they are dissolved in water.

3.00 moles of helium gas (He) are in a container with a volume is 2.00 liters and a temperature is at 298 K. What is the approximate pressure in kilopascals?

Answers

Answer:

3718.628 kPa.

Explanation:

We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm (P = ??? atm).

V is the volume of the gas in L (V = 2.0 L).

n is the no. of moles of the gas in mol (n = 3.0 mol).

R is the general gas constant (R = 0.0821 L.atm/mol.K),

T is the temperature of the gas in K (T = 298.0 K).

∴ P = nRT/V = (3.0 mol)(0.0821 L.atm/mol.K)(298.0 K)/(2.0 L) = 36.7 atm.

To convert from atm to kPa:

∵ 1.0 atm = 101.325 kPa.

∴ P = (36.7 atm)(101.325 kPa/1.0 atm) = 3718.628 kPa.
