It will expand because the helium atoms will move more quickly and get farther apart. This is your answer because as the particles get more heated, they start to increase the kinetic energy and move more.

Answer:

It will expand because the helium atoms will move more quickly and get farther apart.

Explanation:

When a gas absorbs heat, the internal energy of its molecules increases, the gas intend to expand because, with more energy, the molecules will move quickly and will get farther apart.

If the container is not flexible, it will contain the molecules, and the gas pressure will increase, but if it's flexible, it will permit the gas to expand and will expand too.

The change in entropy, ΔS∘rxn , is related to the the change in the number of moles of gas molecules, Δngas . Determine the chan
kifflom [539]

Explanation:

Entropy of a reaction ΔS∘rxn is the degree of disoderliness in a system. Gases generally have a higher degree of disorder compared to liquids. Hence for the reaction 2H2(g)+O2(g) ⟶ 2H2O(l), the entropy decreases sice the reactants are in the gaseous state and the products is in the liquid state of matter

I NEED HELP!!!
True [87]

Answer:

Explanation:

Formula

Heat = m * c * delta t

t = temperature in centigrade.

The first thing you have to do is convert kelvin degrees to centigrade. The conversion factor is - 273. The formula is degrees centigrade = degrees kelvin - 273. It is easier to understand with a couple of examples.

  • 290o K = 290 - 273 = 17
  • 325. K =   325 - 273 = 52

Solution

Heat = 100.0 grams * 4.18 J/g*C * (52 - 17)

Heat = 100 * 4.18 * 35

Heat = 14630 Joules

But you want kj

Heat = 14630 / 100 = 14.63

Answer

Heat = 14.6 kj

The 3rd answer down.

Na²O (sodium oxide) will be a base when exposed to water H²O

Explanation:

Sodium Oxide Na²O, will become Sodium Hydroxide after being exposed to water (at 80% I believe).

The oxygen ion in Na²O has 2 extra electrons which makes it highly charged and very attractive to hydrogen ions. The attraction is so strong that when Na²O comes in contact with H²O, the O(-2) strips off a hydrogen from water, forming 2 x OH ions which of course are still strongly basic.
