A 0.530 M Ca(OH)2 solution was prepared by dissolving 36.0 grams of Ca(OH)2 in enough water. What is the total volume of the solution thus formed? (4 points)

Answer:

An ionic compound, salt is a hard, crystalline substance in which the positive and negative ions are lined up in a regular pattern.

Explanation:

Answer:

2 electrons

Explanation:

Oxygen has 6 valence electrons and to be stable it needs 8. That means it needs 2 more electrons to have a full octet.

Answer:

liquid B

Explanation:

because of the density of liquid A being 8, liquid B being 3 would be less dense

Answer:

1. A map is two dimensional, while a globe is three dimensional

2. A globe is a scaled down representation of the entire Planet Earth. A map can represent an area of any size.

Explanation:

1. A map is usually a sheet of rectangular paper that is a flattened image of an area as seen from the top. A globe on the other hand is a sphere which is a 3D shape.

2. Earth is in the shape of a sphere, so Globes are a smaller representation of the planet. A map can be for a city, state, country, or the world.

Answer:

Yes, water can stay liquid below zero degrees Celsius. There are a few ways in which this can happen. The freezing point of water drops below zero degrees Celsius as you apply pressure. When we apply pressure to a liquid, we force the molecules to get closer together.

Answer: Surface tension has a more complicated effect on capillary pressure: on the one hand, capillary pressure is directly proportional to surface tension. High surface tension liquids, on the other hand, typically have higher contact angles, which lowers capillary pressure.

Answer:

the mantle is layer C.

Explanation:

the crust would be layer A. inner core would be layer D. outer core would be layer B.

In the situation where an ion has a charge of -2, the Lewis structure is affected because it must add two additional electrons.

The Lewis structure is a term to refer to the graphical representation that shows the pairs of electrons in dashes or points of bonds between:

Additionally, the charge of an ionic compound is calculated using the difference in electrical charge between the electrons. On the other hand, an ion is formed by adding or removing electrons, so the magnitude of the resulting charge depends on the number of electrons added or removed.

According to the above, if an ionic compound has a -2 charge, the Lewis structure must add two electrons.

Answer:

it has a fixed volume it can also be compressed

Explanation:

a gases molecules don't move slow because they are not solid and are not compacted.

a gas does not have a fixed shape because there is nothing to hold its shape

Answer: I would say the last one only

Explanation:

Cuz Gases have the following characteristics:

no definite shape (takes the shape of its container)

no definite volume

particles move in random motion with little or no attraction to each other

highly compressible

Answer:

4.37*10^24 atoms of K

Explanation:

1 mol=6.022*10^23 atoms (Avogadro's number)

To convert from mols to atoms multiply the mols of K by Avogadro's number.

7.25 mol K * 6.022*10^23 atoms = 4.36595*10^24 atoms

the variable that we change in an experiment is the Independent Variable. The dependent variable is the outcome and the constant is what remains the same throughout the experiment.

Atomic Particles

Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

Explanation:

Equation:

[tex]{ \rm{2Al_{(s) } + 3Cl _{2(g)} \dashrightarrow \: 2AlCl _{3(s)}}}[/tex]

Answer:

1) Convert percent (m/V) to molarity

percent (m/V)=1.15 grams/100ml=1.15 g/0.1L=11.5g/L

molarity of KBr=mol/L=g/L *(1mol/molecular weight of KBr)=(11.5g/L) * (1mol/119.0g/mol)=0.0966 mol/L=0.0966M

2) calculation of osmol from mol

In solution, KBr dissociates into two ions K+ and Br- so there are 2 osmol of KBr per mol

3) calculation of osmolarity=molarity*2=0.0966*2=0.193 Osm or Osmolar

The atoms that would be expected to be diamagnetic in the ground state is  magnesium

The magnetism of an atom refers to its electronic configuration. A diamagnetic atom is an atom whose electrons are all paired.

A paired electron is an electron that occurs in pairs in its orbital shell.

At their respective ground state, the electronic configuration of the given elements are as follows:

The electronic configuration of magnesium is 1s²2s²2p⁶3s².  As such its a diamagnetic atom.

The electronic configuration of Potassium is 1s²2s²2p⁶3s²3p⁶4s¹. Hence, Potassium has one unpaired electron in its outermost shell.

The electronic configuration of Chlorine is 1s²2s²2p⁶3s²3p⁵. Hence, Chlorine has one unpaired electron in its outermost shell.

The electronic configuration of Cobalt is 1s²2s²2p⁶3s²3p⁶3d⁷4s². Hence, the unpaired electrons of Cobalt in its outermost shell are three.

Therefore, the atoms that are diamagnetic in the ground state is magnesium.
