Hey there!

Molar mass of O3 = 47.9982 g/mol

therefore:

1 mole O₃ ---------------------  47.9982 g

moles O₃ ---------------------- 24 g

moles O₃ = 24 x 1 /  47.9982

moles O₃ = 24 / 47.9982

moles O₃ = 0.500 moles

Answer:

If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt.

A. They are nonreactive gases

Explanation:

Given problem:

Find the molar mass of:

  SO₃ and C₁₀H₈

Solution:

The molar mass of a compound is the mass in grams of one mole of the substance.

To solve this, we are going to add the individual atomic masses of the elements in the compound;

  Atomic mass;

       S = 32g/mol; O = 16g/mol; C = 12g/mol and H = 1g/mol

For  SO₃;

     = 32 + 3(16)

     = 32 + 48

     = 80g/mol

For C₁₀H₈

      = 10(12) + 8(1)

      = 120 + 8

       = 128g/mol

Answer:

The anser is c

Roman numerals are used to indicate oxidation states. Hence, option C is correct.

An oxidation state is a number given to the atom of an element when participating in a chemical reaction.

Roman numerals are used to indicate oxidation states of transition metals.

The names for transition metal compounds often have roman numerals in them, because the roman numerals indicate the charge on the transition metal. But the oxidation state of Cu in CuO is +2, and the oxidation state of Cu in [tex]Cu_2O[/tex] is +1. Name metal first and charge and transition metal with a roman numeral.

The transition metals may form more than one ion, thus it is needed to be specified which particular ion we are talking about. This is indicated by assigning a Roman numeral after the metal. The Roman numeral denotes the charge and the oxidation state of the transition metal ion.

[tex]Fe^{2+}[/tex] would be named iron (II) and [tex]Fe^{3+}[/tex] would be named iron (III).

Hence, option C is correct.

Answer:

2.7g/cm³

Explanation:

Given parameters:

Dimension of the aluminum  = 10.5cm x 10.5cm x 0.1cm

Mass of the aluminum  = 29.8g

Unknown:

Density  = ?

Solution:

Density of a substance is its mass per unit volume;

  Mathematically;

       Density  = [tex]\frac{mass}{volume}[/tex]

Volume of the aluminum  = 10.5cm x 10.5cm x 0.1cm = 11.025cm³

  So, insert the parameters and solve;

  Density  = [tex]\frac{29.8}{11.025}[/tex]   = 2.7g/cm³

Answer:

a. Reactants: F₂ and HCl molecules

Products: Cl₂ and HF

b. 4HCl + 2F₂ ----> 4HF + 2Cl₂

c. Single replacement reaction

Note: The question is not complete. The complete question is found below as well as in the attachment.

Suppose that green spheres represent chlorine atoms, yellow-green spheres represent fluorine atoms, white spheres represent hydrogen atoms, and all the molecules are gases:

a. write a formula for each of the reactants

b. write a balanced equation for the reaction

c. indicate the type of reaction as combination,decomposition, single replacement, double replacement, or combustion

Explanation:

a. From the models shown in the diagram, The reactants are F₂, HCl while the products are Cl₂ and HF respectively

b. Equation for the reaction is given below;

4HCl + 2F₂ ----> 4HF + 2Cl₂

c. The reaction is single replacement reaction such that fluorine gas molecules replace the chlorine atoms in hydrogen chloride to form hydrogen fluoride with the liberation of chlorine atoms as gaseous molecules.

Answer:

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question we have

[tex]density = \frac{2.78}{10} \\ = 0.278[/tex]

We have the final answer as

Atomic weight of metal : 24

Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison so that compounds have a fixed composition of elements

Divalent metal oxide=XO

MW O = 16

MW XO₂ =  X+16

[tex]\tt \%mass=\dfrac{Ar~X}{X+16}\times 100\%\\\\0.6=\dfrac{X}{X+16}\\\\0.6(X+16)=X\\\\0.6X+9.6=X\\\\0.4X=9.6\rightarrow X=24[/tex]

Explanation:

Ca(OH)₂ is the correct chemical  formula unit of an ionic compound.

Chemical  formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols  of elements. It also makes use of brackets and subscripts.

Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form  is called empirical formula.

It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.

There are four types of chemical formula:

1)empirical formula

2) structural formula

3)condensed formula

4)molecular formula
