Two tanks of gas, one of hydrogen, h2, and one ofhelium, he, contain equal numbers of moles of gas. thegram-molecular mass of he is twice that of h2. bothtanks of gas are at the same temperature, 293 k. which statement(s)below is(are) correct when we ignore vibrational motion?

the totalinternal energy of the hydrogen is the same as that of thehelium.

the totalinternal energy of the hydrogen is 1.4 times that of thehelium.

the totalinternal energy of the helium is 1.4 times that of thehydrogen.

the totalinternal energy of the hydrogen is 1.67 times that of thehelium.

the totalinternal energy of the helium is 1.67 times that of thehydrogen.

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit
