The piston-cylinder below is depicted before and after a gaseous reaction that is carried out in it at constant pressure: the temperature is 150k before and 300 k after the reaction. (assume the cylinder is insulated.) which of the following balanced equations describes the reaction? group of answer choices a(g) + b2(g) latex: \longrightarrow ⟶ ab2 (g) a2(g) + b2(g) latex: \longrightarrow ⟶ 2ab(g) 2ab(g) + b2(g) latex: \longrightarrow ⟶ 2ab2(g) 2ab2(g) latex: \longrightarrow ⟶ a2(g) + 2b2(g)

Ithink 2 is the correct

Of course: ) what’s your name ?

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.

Its trait is different and it the organism survive
