Soda has a density pf 1.05 g/mL. What is the mass of 2000 mL of soda?
A. 2100 g
B. 1905 g
C. 0.0005259
D. 2005 g

Answer:

its a heterogeneous mixture.

Explanation:

The heterogeneous mixture has a non-uniform composition and has two or more phases. It can be separated out physically.

A homogeneous mixture is a solid, liquid or gaseous mixture that has the same proportions of its components throughout any given sample. Conversely, a heterogeneous mixture has components in which proportions vary throughout the sample.

Examples of Heterogeneous Mixtures

Sugar and sand form a heterogeneous mixture. If you look closely, you can identify tiny sugar crystals and particles of sand. Ice cubes in cola form a heterogeneous mixture. The ice and soda are in two distinct phases of matter (solid and liquid).

Answer:

Yes, actually it is a compound.

Explanation:

There are important differences between the properties of a mixture and a compound. In this table, the column Mixture refers to the gasses hydrogen and oxygen, and the column named Compound refers to water.

Answer:

17.55 carats

Explanation:

First, there is a need to know the mass of 1.0 mL of diamonds. The density of diamond is 3.51 g/mL and density is the ratio of mass and that of volume. Hence;

mass of diamond = density of diamond x volume.

Since the volume of the diamond is 1.0 mL and the density is 3.51 g/mL,

mass of 1.0 mL of diamond = 3.51 x 1.0 = 3.51 g.

1 g = 5 carats, therefore 3.51 g would be;

                3.51 x 5 = 17.55 carats.

Hence, there would be 17.55 carats of diamond in 1.0 mL of diamond.

The families that have the highest reactivities are the a lkali metals and earth alkali metals . These are located far left on the periodic table. They are highly reactive because they have an shell with only 1 electron and need to complete the shell to become stable. The family that is unreactive is inert elements or noble gases.

The alkali metals (lithium family) are highly reactive while the noble gases (helium family) are highly unreactive.

The alkali metals are the elements of group 1 in the modern periodic table which are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

All alkali metal has their outermost electron in the s-orbital with the outer configuration ns¹. The alkali metals easily lose the outermost electrons to form cations with charge + 1. Therefore they are highly reactive and are stored under oil to stop the reaction with air.

The noble gases have completely filled electronic configurations. The noble gases have a general outer configuration ns²np⁶ so they have completely filled valence shell therefore, they do not feel any attraction for other atoms. Therefore, noble gases exist in monoatomic form. Therefore, noble gases are highly unreactive and also known as inert gases.

Answer:

Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.

Im not sure if this answers your question but here!

Sedimentary rocks are one of three main types of rocks, along with igneous and metamorphic. They are formed on or near the Earth’s surface from the compression of ocean sediments or other processes.

Explanation:

Given that,

Mass of metal cube, m = 20 g

Volume of cube, V =5 mL

We need to find the density of the cube. Mass per unit volume equals density.

[tex]d=\dfrac{m}{V}\\\\d=\dfrac{20\ g}{5\ mL}\\\\d=4\ g/mL[/tex]

So, the density of the cube is 4 g/ml.

We know that the density of Aluminium is 4 g/mL.

So, the cube is not Aluminium cube.

The density of Aluminium is 2.7 g/mL.  The cube is not the Aluminium cube.So, option B and E is correct

Mass of metal cube, m = 20 g

Volume of cube, V =5 mL

The formula for density is as follows:-

[tex]Density=\frac{Mass}{Volume} \\\\[/tex]......(1)

Substitute 20 g for mass, and 5 ml for volume in the above equation as follows:-

[tex]Density=\frac{20\ g}{5\ mL} \\\\=4\ g/mL[/tex]

So, the density of the cube is 4 g/ml.

We know that the density of Aluminium is 2.7 g/mL.  So, the cube is not the Aluminium cube. So option B and E are correct.

Number of neutrons

Explanation:

The mass of an atom is roughly the sum of the number of protons and neutrons it has. If you have the number of protons, all you would need is the number of neutrons to determine the mass.

The process of melting a crystalline solid can be

reversed if the liquid is cooled. The change from the liquid state

to the solid state is called freezing. As the liquid cools, it loses

thermal energy. As a result, its particles slow down and come

closer together. Attractive forces begin to trap particles and the

crystals of a solid begin to form.

"The total kinetic energy of all the particles in a sample of

matter is called thermal energy. Thermal energy, an extensive

property, depends on the number of particles in a substance as

well as the amount of energy each particle has. If either the

number of particles or the amount of energy in each particle

changes, the thermal energy of the sample changes. With identically sized

samples, the warmer substance has a greater thermal energy."

Water particles have strong intermolecular forces.

Explanation:

Water molecules are affected by attraction and repulsion and that causes the water to have strong forces and intermolecular strength to be strong.

Water particles have strong intermolecular forces.

Intramolecular forces are the forces that keep atoms together inside a molecule. Intermolecular forces are forces that exist among molecules. determine intermolecular appeal between H-Cl molecules and intramolecular attraction within H-Cl molecules.
