How many moles are contained in 39 L of F2 gas at STP?
The number of moles contained in 39 L of F2 gas at STP is 1.74mol. Details on how to calculate number of moles can be found below.
How to calculate number of moles?The number of moles of a gas at STP can be calculated using the following formula:
PV = nRT
Where;
P = pressureV = volume n = number of moles R = gas law constantT = temperatureAt STP, the following applies:
T = 273KP = 1 atmR = 0.0821 Latm/molK1 × 39 = n × 0.0821 × 273

A liquid has an empirical formula CCl2, and a boiling point of 1 21 oC. When vapourised, the gaseous compound has a density of 4.93 g/L at 785torr and 1 50oC. What is the molar mass of the compound and what is its molecular weight?
Based on the data given, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu
How can molar mass of a gas be obtained from density, temperature and pressure?The molar mass of a gas can be obtained from density, temperature and pressure using the formula below:
molar mass = density × molar gas constant × temperature/pressureMolar gas constant, R = R = 0.082 L.atm/mol/K.
Temperature = 150 °C = 423 K
Pressure = 785 torr = 1.033 atm
density = 4.93 g/L
molar mass of gas = 4.93 × 0.082 × 423/1.033
molar mass of gas = 165.5 g/mol
Then, molecular weight of the gas = 165.5 amu

The temperature of CI2 is changed from 836.06K to 625.06K.if it's new volume is 14.509L what was its original volume in liters
V1= 19.229L
Explanation:
V1/T1 = k
V1/836.06=14.509/625.06
V1/836.06= 0.023
V1 = 19.229L
The temperature of CI₂ is changed from 836.06K to 625.06K. If it's new volume is 14.509L then its original volume in liters was 19.4 L.
What is combined gas law?The combined gas law is the law of of gaseous state which is made by combination of Boyle's law, Charle's law, Avogadro's law and Gay Lussac's law.
It is a mathematical expression that relates Pressure, Volume and Temperature.
(P1 × V1)÷T1 = (P2 × V2)÷T2
We can also use the following relation-
PV = nRT
According to the question, Pressure is constant and we can write the formula as-
V1÷T1 = V2÷T2
T1 = 836.06 K
T2 = 625.06 K
V1 = ?
V2 = 14.509 L
V1 = 19.4 L
Therefore, The temperature of CI₂ is changed from 836.06K to 625.06K. If it's new volume is 14.509L then its original volume in liters was 19.4 L.

How are fluids used and controlled in manufactured devices?
Answer:
Fluid power systems perform work by a pressurized fluid bearing directly on a piston in a cylinder or in a fluid motor. A fluid cylinder produces a force resulting in linear motion, whereas a fluid motor produces torque resulting in rotary motion. Within a fluid power system, cylinders and motors (also called actuators) do the desired work. Control components such as valves regulate the system.

Explanation:
According to the specific heat capacity, water has lowest specific heat and greatest is that of silver owing to their temperature differences.
What is specific heat capacity?
Specific heat capacity is defined as the amount of energy required to raise the temperature of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.
It varies with temperature and is different for each state of matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.It is different for different substances.

You are a NASA engineer. You are the chief engineer for the Apollo 13 mission to the moon. The astronauts are running out of oxygen and need to get rid of the excess carbon dioxide. You know that sodium hydroxide (NaOH) has been suggested as a means of removing carbon dioxide from the spacecraft cabin. The filter which they had been using is fully saturated and no longer works. You remember that the astronauts have a 5000. g container of sodium hydroxide on the ship. You also know that sodium hydroxide can be used to remove carbon dioxide.
Use the following reaction: NaOH + CO2 → Na2CO3 + H2O
The astronauts have 2 days left before they land on Earth. You know that there are three astronauts, and each astronaut emits roughly 500. g Of carbon dioxide each day. Is there enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon dioxide, or are the astronauts doomed? SHOW ALL YOUR WORK - DON’T FORGET TO BALANCE THE EQUATION
Guiding Questions: How many grams of CO2 are produced in a day? How many grams of CO2 are produced in both days? How many grams of NaOH do you need to get rid of 3000 g of CO2?
Answer:
We know that there are three astronauts and each one of them emits 500 grams of carbon dioxide each day, so the total carbon dioxide emitted each day.
Explanation:
From the mole ratio of the reaction, there is not enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon
What was of Sodium hydroxide is required?The mass of sodium hydroxide required depends on the mass of CO2 produced by the astronauts.
The mass of CO2 produced by the astronauts is calculated as follows;
Mass of CO2 produced = 3 × 2 × 500 g = 3000 g of CO2
The mass of sodium hydroxide required is calculatedfrom the eqaution of the reaction given below:
[tex]2NaOH + CO_2 → Na_2CO_3 + H_2O \\ [/tex]2 moles of sodium hydroxide reacts with 1 mole of CO2
Molar mass of NaOH = 40 g/mol
Molar mass of CO2 = 44 g/mol
Mass of sodium hydroxide required = 3000 g × 2 × 40/44 = 5454.54 g
Therefore, there is not enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon.
