The hydrogen is collected at 23вЊ and 735mmHg.

If 0.515g of magnesium is added to HCl, it makes hydrogen gas and magnesium chloride.What is the pressure in the (same sized) cylinder after the explosion? The mixture explodes and heats the cylinder to 150вЊ. Five grams of octane (C8H18) and enough oxygen to burn it are in an automobile cylinder compressed to 20 atm at 28вЊ.How many liters of product at 950 mmHg and OвЊ is produced by the burning of three liters of acetylene (C2H2) at 5 atm and 20вЊ?.What volume of carbon dioxide is produced at 1 Atm? A 250 Kg tank of liquid butane (C4H1O) burns to produce carbon dioxide at 120вЊ.What is the added mass of the tank due to the gas? A nine liter tank has 150 atmospheres of bromine in it at 27вЊ.

What is the mass of 25 liters of fluorine gas at 2.85 atm, 450вЊ?.How many milliliters of hydrogen at 0вЊ and 1400 mmHg are produced if 15g of magnesium reacts with sulfuric acid?.How many liters of ammonia at STP are produced when 10 g of hydrogen is combined with nitrogen?.What is the mass of 15 liters of chlorine gas at STP?.What is the mass of neon in a 625 mL neon tube at 357 mmHg & 25вЊ?.Which diffuses faster, the bad smell from a cat-pan due to ammonia or an expensive French perfume with an average molecular weight of 170 g/mol? 'How much faster does the faster one diffuse?.At what altitude should airplane cabins be pressurized? Up to about what altitude should you be able to use unpressurized pure oxygen? (Express your answer in feet above Mean Sea Level, or MSL.) As a rule of thumb, the air pressure decreases one inch of mercury each thousand feet of altitude above sea level. air pressure begin to become 'light-headed' at about 0.10 atm oxygen. The usual partial pressure of oxygen that people get at sea level is 0.20 atm., that is, a fifth of the usual sea level air pressure.A SCUBA tank is filled with air at 16.7 atm at 24вЊ, but someone leaves it out in the sun to warm to 65вЊ.A constant pressure tank of gas at 1.01 atm has propane in it at 15вЊ when it is at 255 cubic meters.You will have to use a weighted average for the molar mass of air.) What is the mass of air in an automobile tire of 19.7 L and internal pressure of 46.7 PSI at 24вЊ? (That pressure is the same as the 32 PSI difference you usually measure as the tire pressure 32 PSI + 14.7 PSI. What volume of air at standard pressure gets packed into an 11 ft 3 SCUBA tank at the same temperature at 15.8 atmospheres? (Use SATP conditions as standard).To what temperature must the balloon get in order to fill out to 60,500 cubic meters?

There will be a small increase in pressure from 785 mmHg to 790 mmHg, but the major effect wanted is an increase in volume so the balloon can lift its cargo.

An enormous (57,400 cubic meter) expandable helium balloon at 22.0вЊ is heated up by a fire under it and the action of the sun on the dark plastic covering on top.

What is the volume of the tube after it has heated? The pressure in the tube is 739 mmHg, but it does not change as the temperature increases.

257 mL of oxygen in a gas tube goes from 17вЊ to 42вЊ from being out in the sun.

What is the volume of the same helium at 320 K and 800 mmHg?

Helium takes up 5.71 liters at OвЊ and 3.95 atmospheres.

785 mmhg to atm
