Chemistry
1 answer:
stepan [7]2 years ago
7 0

Answer:

See below

Explanation:

.045 liter / 22.4  l / mole   * 6.022 x 10^23 molecules/mole   * 2 atoms/molecule  =

( * 2 becuase nitrogen gas is diatomic)

In the following equation, ______ is being oxidized and ______ is being reduced.
Mashcka [7]

oxidation \: number \: of \: oxygen =  \\ before \: rxn =  - 2 \\ after \: rxn =  - 2

oxidation \: number \: of \: hydrogen = \\ before \: rxn =  + 1 \\ after \: rxn =  \\ 2x - 2 = 0 \\ x =  + 1

oxidation \: number \: of \: carbon =  \\ before \: rxn =  \\ x  - 6 =  - 2 \\ x = 4 \\ after \: rxn =  \\ x - 4 = 0 \\ x = 4

<h2>Option A</h2>

oxidation \: numbers \: remain \: constant \\ so \: none \:a re \: undergoing \: oxidation \: \\ nor \: reduction \:

What are the 5 types of matter?
sdas [7]

The five types of states of matter are solid, liquid, gas, plasma and Bose-Einstein condensate.

Solid objects do not move a lot relative to themselves. Their molecules stay stacked neatly with no intermolecular spaces. They do not have much energy, or heat hence the molecules in solid state don't show movement.

Liquid state have more heat and more energy and a little more intermolecular space than solid. Their molecules are no longer stacked neatly due to presence of air capsules, but they still touch each other. Their structure is uncertain and can flow, their shape will alter quickly and dramatically with outside forces, but they will essentially remain a single mass unless pushed apart.

Gasses have even more energy than liquid and solid. Due to presence of high intermolecular spaces they flow like liquids, but are even more susceptible to the forces acting on them. Their molecules don’t touch each other, but are still close enough to bounce into one another frequently.

Plasma is the state of matter which is like a gas on steroids. Molecules of plasma might start in the same area, but rarely touch each other. Plasma molecules have lost electrons, and have become charged. Plasma molecules set other things on fire, and even vaporize them.

Bose-Einstein condensate or BEC was first created by scientists in the year 1995. This was created using a combination of lasers and magnets, Eric Cornell and Carl Weiman, scientists at the Joint Institute for Lab Astrophysics (JILA) in Boulder, Colorado, cooled a sample of rubidium to within a few degrees of absolute zero.
