Answer:

smoke
marshmallow
paint
Body spray

Explaination:

Firstly, what are colloids?

Colloids are a mixture of two substances:

one of those substances are insoluble and inseparable

There are 4 types of colloids:

Sol- Solid in a liquid
Emulsion- Liquid in a liquid
Foam- Gas in solid/liquid
Aerosol- Solid/liquid in gas

So on to the answers:

Smoke consists of solid and gas and since the solid is being carried by the gas, it is a solid in a gas (aerosol)
Marshmellow consists of tiny air bubbles and sugar(solid), the air bubbles is inside the solid making it a gas in a solid (foam)
Body spray turns gas into liquid after spraying it through the can, making it a liquid in a gas (aerosol)
Paint dries up to become solid which makes it a solid is a liquid (sol)

Hope y'all understand

What is the molarity of 5.60 mol of sodium carbonate in 1500 ml of solution?

FrozenT [24]

Answer:

3.74 M

Explanation:

We know that molarity is moles divided by liters. The first thing to do here is convert your 1500 mL of solution to L. There's 1,000 mL in 1 L, so you need to divide 1500 by 1000:

1500 ÷ 1000 = 1.50

Now you can plug your values into the equation for molarity:

5.60 mol ÷ 1.50 L = 3.74 M

Can someone help me please

MArishka [77]

Answer:

Group 4A (or IVA) of the periodic table includes the nonmetal carbon (C), the metalloids silicon (Si) and germanium (Ge), the metals tin (Sn) and lead (Pb), and the yet-unnamed artificially-produced element ununquadium (Uuq).

The Group 4A elements have four valence electrons in their highest-energy orbitals (ns2np2). Carbon and silicon can form ionic compounds by gaining four electrons, forming the carbide anion (C4-) and silicide anion (Si4-), but they more frequently form compounds through covalent bonding. Tin and lead can lose either their outermost p electrons to form 2+ charges (Sn2+, the stannous ion, and Pb2+, the plumbous ion) or their outermost s and p electrons to form 4+ charges (Sn4+, the stannic ion, and Pb4+, the plumbic ion).

Carbon (C, Z=6).

Carbon is most familiar as a black solid is graphite, coal, and charcoal, or as the hard, crystalline diamond form. The name is derived from the Latin word for charcoal, carbo. It is found in the Earth's crust at a concentration of 480 ppm, making it the 15th most abundant element. It is found in form of calcium carbonate, CaCO3, in minerals such as limestone, marble, and dolomite (a mixture of calcium and

Binary molecular (covalent) compounds are formed as the result of a reaction between two nonmetals. Although there are no ions i

ollegr [7]

Answer:

Binary molecular compounds are the compounds consisting of two non-metallic elements. Examples of binary molecular compounds include: NO2, HCl, HF, P2O5 e.t.c.

Rules For Naming Binary Molecular Compounds

Naming binary molecular compounds is quite easy,

1. The first element is given its name.

2. The second element is given its root name (such as, hydro, carb,ox, chlor e.t.c.) followed by suffix ide.

Name of N2O4 - Dinitrogen tetraoxide

Chemical Formula of;

iodic acid: HI

disulfur trioxide: S2O3

dinitrogen monoxide: N2O

hydrofluoric acid: HF

Difference between Binary acid and an oxyacid

An oxyacid is an acid consisting of an oxygen atom bonded to a hydrogen atom and at least one other non-metallic element. Examples of oxyacids include HNO3, H2SO4 e.t.c.

Binary acids are the acids consisting of hydrogen atom bonded to a non-metallic element. Examples include HF, HCl, HI e.t.c.
