At the end of seafloor spreading, where does the molten rock solidify?

1st question: A mixture is when the components of a mixture can be easily separated and that the components each keep their original properties.

2nd question:A phase is any part of a sample that has a uniform composition and properties.By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers.

Heterogeneous mixtures are not uniform in composition. Examples would be wood or blood. Homogeneous mixtures are uniform through out. Typically you can see through them.

Explanation:

Use Avogadro's number

Answer:

34.9103 or 34.9 g

Explanation:

Remember Density is a broken heart: m/v.

In this scenario (Let x = # of grams in the sample of gasoline),

D = 0.7198 g/mL = x g / 48.5 mL

So,

(0.7198 g/mL) * (48.5 mL) = x g

x g = 34.9103 = 34.9 g (Accounting for Significant Figures)

The position where the moon is located where its shadow may sometimes reach Earth is position A .

We know that in the outer space there are a lot of celestial bodies that can be found. Now we know that a celestial body is one that can be found in the outer space and the moon and the sun are all parts of the celestial bodies that we can find in the solar system.

In this case we  are being asked for the position of the moon that could lead to an eclipse where the moon would come between the earth and the sun and that is the position A.

No, input energy is not equal to useful output energy, if it is an electric toothbrush.

Electrical Energy is the useful type of energy produced in an electric toothbrush.

If input energy is equal to useful output energy. This means that the total amount of energy that is in an isolated system (such as an engine or a generator) remains constant (conserved) over time.

However, the total amount of useful energy output of an isolated system is never equal to the total energy input.

Answer:Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids.

Explanation:Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.

Answer:

3. Inverse 1. Direct

Explanation:

P- pressure

V - volume

T - temperature

P1*V1 / T1 = P2*V2 / T2 ...... (1)

That's the general gas law with the combined ideas of charles, boyle & lussac.

Whenever you are restricted as "constant" temperature, volume, or pressure...cancel them off of your equation.

in this case 3. is indirectly telling us to cancel the temperature (T).

so we'll be left w P1*V1 = P2*V2

now notice that any relation ship that is multiplied like the one above consists of inversely related quantities. & so we conclude that-

P & V are inversely proportional or have an inverse relationship.

similarly in 1. we'll cancel p off of the general formula (1)

to be left with V1/T1 = V2/T2

also note that quantities involved in division are directly related to each other & hence the answer.

Molecular structure affects the strength of electrostatic forces, which can affect the boiling point of a substance is the statement that correctly describes the relationship between these terms.

The molecular structure is the way in which the atoms that are in a molecule are arranged in space, this is defined by a series of forces that hold the atoms together in a specific arrangement.

The boiling point is the temperature at which the vapor pressure of the liquid equals the pressure that surrounds the liquid, when this happens, the liquid transforms into gas.

Therefore, we can conclude that the boiling point depends on the molecular mass of the substance and the type of electrostatic forces present, that is, the bonds that the atoms establish with each other to form the molecule (molecular structure).

Answer:

4.58g

Explanation:

1.) What is the molar mass of CaCI2?

= 110.98 g/mol

2.) Find the mols

[tex]conc = \frac{mol}{volume(l)} [/tex]

conc × volume= mol

0.125 M x 0.33 L = 0.04125mol ( 330mL was converted to "L" by dividing 330 by 1000)

3.) The mass(g)

g= mol x atomic weight

g= 110.98g/mol × 0.04125

= 4.58 g

# NOTE M = mol/L

Answer:

H20

Explanation:

Because H20 has hydrogen bonding and this is one of the strongest IMF

Answer:

The molecular structure affects solubility mainly biased on its polarity or bonded ions.

Explanation:

Polar molecules will better interact with the water molecules and will dissolve easier. Nonpolar molecules can dissolve if they are small enough, however they don't interact well with the polar molecules. Bonded ions, such as NaCl split into a cation Na and an anion Cl which the positive charge on the Na will be attracted to the oxygen, and the negatively charged Cl will be attracted to the positive Hydrogen.

**Remember this rule, like dissolves like, meaning nonpolar dissolves nonpolar and polar dissolves polar.

The free energy change of the reaction; Fe (s) + Au3+ (aq) -> Fe3+ (aq) + Au (s) is calculated to be -443.83KJ/mol.

For the reaction shown in question 7, we can divide it into half equations as follows;

Oxidation half equation;

6 Al (s) -------> 6Al^3+(aq) + 18e

Reduction half equation;

3Cr2O7^2-(aq) + 42H^+(aq)   + 18e -----> 6Cr^3+(aq) + 21H2O(l)

The balanced reaction equation is;

6Al(s) + 3Cr2O7^2-(aq) + 42H^+(aq)   -----> 6Al^3+(aq) + 6Cr^3+(aq) + 21H2O(l)

The E° of this reaction is obtained from;

E° anode = -0.04 V

E°cathode = +1.50 V

E° cell = +1.50 V - (-0.04 V) = 1.54 V

Given that;

ΔG° = -nFE°cell

n = 3, F = 96500, E°cell = 1.54 V

ΔG° = -(3 × 96500 × 1.54)

ΔG° = -443.83KJ/mol

Inside the Atom

Just like bricks are the building blocks of a home, atoms are the building blocks of matter. Matter is anything that has mass and takes up space (volume). All matter is made up of atoms. The atom has a nucleus, which contains particles of positive charge (protons) and particles of neutral charge (neutrons). Surrounding the nucleus of an atom are shells of electrons - small negatively charged particles. These shells are actually different energy levels and within the energy levels, the electrons orbit the nucleus of the atom.
