Answer:Other names for U.S. customary units
Another term is the foot–pound–second (FPS) system, as opposed to centimeter–gram–second (CGS) and meter–kilogram–second (MKS) systems.

Answer:</h3>
292.10 mL
<h3>
Explanation:</h3>
From the question we are given;
- Initial volume, V1 of Ne gas is 500 mL
- Initial pressure, P1 of Ne gas is 0.868 atm
- Initial temperature, T1 of Ne gas is 55°C
- but, K = °C + 273.15, thus, T1 = 328.15 K
- Final pressure of the gas, P2 = 1.35 atm
- Final temperature of the gas, T2 = 25°C
= 298.15 K
We are required to calculate the new volume, V2 of the gas;
Using the combined gas equation;
Rearranging the formula we can calculate the new volume, V2;
Therefore, the new volume is 292.10 mL
Answer:
174.8 g/m is the molar mass of the solute
Explanation:
We must apply colligative property of freezing point depression.
ΔT = Kf . m . i
ΔT = T° freezing pure solvent - T° freezing solution (0° - (-2.34°C) = 2.34°C
Kf = Fussion constant for water, 1.86 °C/m
As ascorbic acid is an organic compound, we assume that is non electrolytic, so i = 1
2.34°C = 1.86°C/m . m
2.34°C / 1.86 m/°C = 1.26 m
This value means the moles of vitamin C, in 1000 g of solvent
We weighed the solute in 250 g of solvent, so let's calculate the moles of vitamin C.
1000 g ___ 1.26 moles
In 250 g ___ (250 . 1.26)/1000 = 0.314 moles
This are the moles of 55 g of ascorbic acid, so the molar mass, will be:
grams / mol ⇒ 55 g/0.314 m = 174.8 g/m
Answer:
Answer here is A: Transparent colour."
Explanation:
Hydrogen bonds here in water provides a lot of benefits which includes cohesion, releasing heat when forming, Also because of the fact that water molecules are polar, they form hydrogen molecules and give water some characteristics which ranges from high boiling point, relative gravity, adhesion ad also cohesion. It is also known that oxygen atom attracts the electrons more strongly than the hydrogen.
A transparent colour falls in no place and do not really have any correlation in oxygen and hydrogen relationship.
