Answer:

A. Gas

Explanation:

The physical state, or phase, is a way that the molecules are distributed at a space. The phase depends on the molar mass of the compound, on the internal forces of it, and the temperature and the pressure.

As high is the molar mass, as difficult is to the compound be "free" in a gas phase because it's too "heavy". As strong is the internal forces, as difficult is for the compound to have more internal distances, its components intended to be together.

As higher is the temperature and the pressure, the internal energy of the compound intends to increase, their components have higher velocities, and because of that, they intend to be more separated. So, it's most likely to it to be at a gas phase.

But the other phase can be presented in higher temperatures and pressures, all the criteria must be analyzed.

The molarity of concentrated acetic acid is 17.45 M. When acetic acid is diluted in water it is commonly called vinegar with a m

Sladkaya [172]

M1 = 17.45 M

M2 = 0.83 M

V2 = 250 ml

M1. V1= M2. V2

V1 = (M2. V2)/M1 = (0.83× 250)/ 17.45= 11.89 ml

Question 7 (Essay Worth 5 points)

Lubov Fominskaja [6]

The periodic table of elements is divided into columns and rows. The vertical columns represent the groups while the horizontal rows represent the periods. A group of elements usually have similar physical and chemical properties. The first column of the periodic table is made up of 7 elements including SODIUM.

1. The name of the element chosen is sodium and its chemical symbol is Na.

2. Sodium is a metal and thus it has metallic properties.

3. Sodium belongs to group one elements whose family name is ALKALI METALS.

4. The neutral atom of sodium is made up of 11 protons, 11 electrons and 12 neutrons.

Mol sulfuric acid = 19 g * (1 mol) / (98.1 g) = 0.19367 mol
mol H2O = 0.19367 mol H2SO4 * (2 H2O) / (1 H2SO4)
= 0.387359 mol H2O
grams H2O = 0.387359 mol H2O * (18 g)/(1 mol)
= 6.97 g
The answer is 7.0 grams of water

Sodium dodecanoate is soluble in water even though it contains a large hydrophobic segment. How does this molecule interact with

velikii [3]

Answer:

Sodium laurate, also known as sodium dodecanoate, is a soap. It is the salt of lauric acid. It is an amphiphilic organic molecule which is composed of a hydrophilic head (polar ) and a hydrophobic tail (non-polar fatty acid).

In a aqueous solution, it leads to the formation of a micelle. The hydrophilic head of the molecule interacts with the surrounding polar solvent molecules. Thereby, making the micelle soluble in the solution. Whereas, the hydrophobic tails present in the core of micelle, interacts with the non-polar oil particles.

Which is associated with a fission reaction? *

podryga [215]

Answer: Radioactive waste

Explanation:

The nuclear fission reaction consists of heavy atomic particles or heavy nucleus, like plutonium and uranium and in radioactive heavy metals. In the fission reaction the nucleus get split into equal masses of particles. This process is associated with release of large amount of energy. The fission of radioactive waste can cause deadly mutations in living beings.
