Answer:

RbCIO2 rubidium chlorite magnesium hypocarbonite.

There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, RbCIO[tex]_2[/tex] is named as rubidium chlorite magnesium hypo carbonite.

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

An ionic compound is a metal and nonmetal combined compound. Ionic compound are very hard. They have high melting and boiling point because of strong ion bond.

The compound that is ionic in nature can be dissociated very easily in water. Since ionic compounds are polar in nature, they readily dissolve in water. The name of the given compound is rubidium chlorite magnesium hypo carbonite.

Therefore, RbCIO[tex]_2[/tex] is named as rubidium chlorite magnesium hypo carbonite.

Answer:

should be D

Explanation:

Explanation:

The chemical reaction that describes the combustion of methane is

[tex]\text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O}[/tex]

We need to convert the mass of methane to moles:

[tex]0.00880\:\text{g} × \dfrac{1\:\text{mol CH}_4}{16.04\:\text{g}}[/tex]

[tex]= 5.49×10^{-4}\:\text{mol CH}_4[/tex]

Now use the molar ratios to determine the amount of oxygen used during the combustion:

[tex]5.49×10^{-4}\:\text{mol CH}_4×\left(\dfrac{2\:\text{mol O}_2}{1\:\text{mol CH}_4}\right)[/tex]

[tex] = 0.00110\:\text{mol O}_2[/tex]

Converting this to grams, we find that the mass of oxygen is

[tex]0.00110\:\text{mol O}_2×\left(\dfrac{15.999\:\text{g O}_2}{1\:\text{mol O}_2}\right)[/tex]

[tex] = 0.0176\:\text{g O}_2[/tex]

Answer:

he model of the atom changed and what additional evidence would require the model to change again.​

because ;

Explanation:

This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of their experiments were a surprise and they did not fit with the existing model. Scientists changed the model so that it could explain the new evidence.

Atomic model keep changing because the electrons around the nucleus are not fixed and they keeps rotating or changing their position in valence orbits around the nucleus. In one moment they are present on one side of the nucleus and at very next moment they will be on the other side due to their continuous rotation.

Answer:

B.

Explanation:

The statement that describes the number of protons in each atom of an element is

B. The number of protons is given by the atomic number, which increases by one moving from left to right across each row of the periodic table.

An atom is the smallest divisible particle that is very small, and different substances are made up of atoms. An atom is made up of electrons, protons, and neutrons.

The elements are made up of atoms. The number of protons equals the atomic number of the element. The periodic table is organized as increasing atomic numbers from left to right.

Thus, the correct option is B, The number of protons is given by the atomic number, which increases by one moving from left to right across each row of the periodic table.

Answer:3.935g/cm3

Explanation:39.35 g. /10cm3 = 3.935g/cm3

10 cm³ of metallic cylinder has a mass of 39.35 g. The density of this cylinder is 3.935 g/cm³.

Density is a measure of the amount of mass per unit volume of a substance. It is an intensive physical property, meaning that its value does not change depending on the size of the object.

Density is calculated by dividing an object’s mass by its volume.

The density of water is 1,000 kg/m³ at 4°C. The unit of density is kg/m³ (kilogram per cubic meter). The SI unit of density is kg/m³

Density = mass/volume

            = 39.35 g/10 cm³

            =3.935 g/cm³.

The given data is as follows:

Atom number   Protons   Neutrons   Electrons

1                          9               8                9

2                         9               9                8

4                         9               10               9

The charge on an atom is given by the relation:

Charge = number of protons - number of electrons

For atom 1: charge = 9 - 9 = 0

Atom 2 : charge = 9-8 = 1

Atom 3: charge = 9 -10 = -1

Atom 4 : charge = 9-9 = 0

Answer:

8.3g

Explanation:

d=m/v

m=d*v

m=0.893*9.29

m=8.3g

If the density of carbon tetrachloride is 0.893 g/mL. The mass of the compound will be 8.3 g.

Mass is the quantity of matter. The mass can be calculated by multiplying density with the volume. The evaluation of how close something is packed. As the mass per unit volume, it has that definition.

Volume is the space occupied by the object. The liquid that weighs heavier is denser if you weigh two liquids with similar volumes or amounts. A substance that is less dense than water will float if it is gently introduced to the water's surface.

So the formula will be d = m / v

m = d x v

The density of carbon tetrachloride is 0.893 g/m

The volume of carbon tetrachloride is 9.29 mL

What the mass is?

Putting the value in the formula

m = 0.893  x 9.29 = 8.3g

Thus, the mass of the compound will be 8.3 g.
