Answer:

Here are a few more examples:

Smoke and fog (Smog)

Dirt and water (Mud)

Sand, water and gravel (Cement)

Water and salt (Sea water)

Potassium nitrate, sulfur, and carbon (Gunpowder)

Oxygen and water (Sea foam)

Petroleum, hydrocarbons, and fuel additives (Gasoline)

Heterogeneous mixtures possess different properties and compositions in various parts i.e. the properties are not uniform throughout the mixture.

Examples of Heterogeneous mixtures – air, oil, and water, etc.

Examples of Homogeneous mixtures – alloys, salt, and water, alcohol in water, etc.

Answer:

Chemical equation:

Sr + S → SrS

Explanation:

Mg react with sulfur and form magnesium sulfate.

Chemical equation:

Mg + S → MgS

The oxidation state of magnesium is +2 it loses its two valance electrons while sulfur gain two electrons to complete the octet. That's why one atom of magnesium combine with one atom sulfur.

Chemical equation:

Sr + S → SrS

The oxidation state of strontium is +2 it loses its two valance electrons while sulfur gain two electrons to complete the octet. That's why one atom of strontium combine with one atom sulfur.

a gas has a volume of 350 cubic centimeters at 740 mmHg. how many cubic centimeters will the gas occupy at a pressure of 900 mmH

Harrizon [31]

Answer: 287.8 cm3

Explanation:

Given that:

Initial volume of gas V1 = 350 cm3

Initial pressure of gas P1 = 740 mmHg

New volume V2 = ?

New pressure P2 = 900 mmHg

Since, pressure and volume are involved while temperature is constant, apply the formula for Boyle's law

P1V1 = P2V2

740 mmHg x 350 cm3 = 900mmHg x V2

V2 = (740 mmHg x 350 cm3) /900mmHg

V2 = 259000 mmHg cm3 / 900mmHg

V2 = 287.8 cm3

Thus, the gas will occupy 287.8 cubic centimeters at the new pressure.

Determine the mass in grams of each of the following:

lukranit [14]

Answer:

A) 9.60 g

B) 19.2 g

C) 28.8 g

Explanation:

A) Elemental oxygen mass is 16.00 g/mol, so in 0.600 mol of elementar oxygen there is 9.60 g

0.600 mol x 16.00 g/mol=9.60 g

B) Oxygen molecular mass is 32.00 g/mol, so in 0.600 mol of oxygen molecules there is 19.2 g

0.600 mol x 32.00 g/mol=19.2 g

C) Ozone molecular mass is 48.00 g/mol, so in 0.600 mol of oxygen molecules there is 28.8 g

0.600 mol x 48.00 g/mol=28.8 g
