CO2 = Carbon dioxide

Hope this Helps!!Hope this Helps!!:)
Answer 2

There are two types of chemical compound one is covalent compound and another is ionic compound in chemistry. In ionic bonds, electrons are completely transferred. Therefore, the name of CH[tex]_4[/tex]  and CO[tex]_2[/tex]  are Methane and Carbon dioxide respectively.

What is chemical Compound?

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

Covalent compounds are formed by covalent bond and ionic compounds are formed by ionic bond. Covalent bond is formed by sharing of electron and ionic bond are formed by complete transfer of electron. Ionic bonds are stronger than covalent bonds. The melting and boiling points are higher in ionic compounds.

The faster rate of reaction was caused by using a higher temperature. Explain, in terms of particles, why a higher temperature causes a faster rate of reaction.

Answers

Answer:

Increasing the temperature a reaction takes place at increases the rate of reaction. At higher temperatures, particles can collide more often and with more energy, which makes the reaction take place more quickly.

Answers

Answer: Rutherford's model was the first propose of the existence of small, dense nucleus's.

Explanation: The atom, as described by Ernest Rutherford, has a tiny, massive core called the nucleus. The nucleus has a positive charge. Electrons are particles with a negative charge. Electrons orbit the nucleus. The empty space between the nucleus and the electrons takes up most of the volume of the atom.

At equilibrium at 2500K, [HCl]=0.0625M and [H2]=[Cl2]=0.00450M for the reaction H2+Cl2 ⇌ HCl.
a. Determine the balanced equation and write the equilibrium expression
b. Determine the K eq
c. Will this process favor the reactants or products at equilibrium?

Answers

Answer:

a. [tex]H_2+Cl_2 \rightleftharpoons 2HCl[/tex]

b. K = 192.9

c. Products are favored.

Explanation:

Hello!

a. In this case, according to the unbalanced chemical reaction we need to balance HCl as shown below:

[tex]H_2+Cl_2 \rightleftharpoons 2HCl[/tex]

In order to reach 2 hydrogen and chlorine atoms at both sides.

b. Here, given the concentrations at equilibrium and the following equilibrium expression, we have:

[tex]K=\frac{[HCl]^2}{[H_2][Cl_2]}[/tex]

Therefore, we plug in the data to obtain:

[tex]K=\frac{(0.0625)^2}{(0.00450)(0.00450)}\\\\K=192.9[/tex]

c. Finally, we infer that since K>>1 the forward reaction towards products is favored.

The molar mass of two equally sized samples of unknown gaseous compounds is shown in the table. Molar Mass Comparison Gas Molar Mass A 17 g/mol B 36.5 g/mol Which statement describes the density and diffusion of both gases at STP? Gas A has a higher density and diffuses faster than Gas B. Gas A has a higher density and diffuses slower than Gas B. Gas A has a lower density and diffuses faster than Gas B Gas A has a lower density and diffuses slower than Gas B.

Answers

Answer:

Effusion  is the process of a gas being poured out through a hole diametrically smaller than the structural exit of the container.

A lighter gas effuses faster than a heavier gas.

Thus gas A has a lower density and effuses slower than Gas B.

Explanation:

The gas with a lower molar mass will have a lower density and diffuses at a slower rate. Thus gas A has a lower density than gas B and diffuses slower than gas B.

Three points should be noted here;

The density of any substance is related to the molar mass.[tex]D=M/V[/tex], where [tex]D[/tex] is the density, [tex]M[/tex] is the mass and [tex]V[/tex] is the volume of the substance.The density of the gas is directly proportional to the molar mass of the gas.

Hence the gas A has lower density and the gas B has higher density as the molar mass of A is [tex]17 g/mol[/tex] and of B is [tex]36.5 g/mol[/tex].

About Diffusion please note the below points;

Diffusion is the process of movement of a substance from the area of higher concentration to the area of lower concentration.The gas with a smaller mass will diffuse slower in rate than the gas with a higher mass.

Hence the gas A diffuses slower in rate than gas B.

Thus the correct answer is "Gas A has a lower density and diffuses slower than Gas B".

Oxidation numbers of oxygen in H2PO4 and H2O2 is_____ respectively

Answers

Answer:

-2 , -1

Explanation:

H2PO4=-1

+1 × 2 + +5 + 4 ×O=-1

7+ 4O =-1

4O= -8

O = -2

H2O2=0

+1 × 2 +2 x O =0

2 + 2O=0

O= -1

(As the oxidation number of Hydrogen is +1 , and we have 2 hydrogen atoms so we multiply by 2 , while the oxidation number of P is +5 in this equation, also the compound as a whole equals -1 , then we do the steps as followed)

(while the other compound as a whole equals zero , and doing steps as followed)

A balloon occupies 175 cm at 25.0 C. What volume will it occupy at 42.5 °C?

Answers

175 cm³ instead of 175 cm.

Answer:

297.5 cm³

Explanation:

From the question;

Initial volume; V1 = 175 cm³

Initial temperature; T1 = 25°C

Final temperature; T2 = 42.5°C

From Charles law we can find the volume V2 from the equation;

V1/T1 = V2/T2

Making V2 the subject gives;

V2 = V1 × T2/T1

V2 = (175 × 42.5)/25

V2 = 297.5 cm³

Lithium forms ions with a charge of lt Oxygen forms ions with a charge of 2- in the ionic compound lithium oxide, how many
atoms of lithium will there be if there is 1 atom of oxygen?
HELP ME

Answers

Answer:

There are 2 lithium atoms in the ionic compound lithium oxide, Li₂O

Explanation:

The charge of ions formed by lithium = 1⁺

The charge of ions formed by oxygen = 2⁻

In the ionic compound lithium oxide having 1 atom of oxygen, we have;

For the compound to be electronically neutral, the sum of the charges of the atoms in the ionic compound is zero

The charge of 1 atom of oxygen in the lithium oxide compound + The charge of the 'n' number of lithium atoms in the lithium oxide compound = 0

∴ 2⁻ + n × 1⁺ = 0

n × 1⁺ = 0 - 2⁻ = 2⁺

n = 2⁺/(1⁺) = 2

n = 2

The number of lithium atoms in the lithium oxide compound, n = 2

Therefore, there are two lithium atoms in the ionic lithium oxide (Li₂O) compound

a 31 g sample of a compound that contained only

Answers

The question is incomplete, the complete question is;

A 31 g sample of a compound that contains only the elements C,H and N is completely burned in O2 to produce 44.0 g of CO2, 45.0 g of H2O, and 92.0 g of NO2. Determine the empirical formula of the compound.

Answer:

CH5N2

Explanation:.

Mass of C = 44.0g/44.0 g/mol = 1 mol * 1 = 1 mole of C

Mass of H = 45.0 g/18 g/mol = 2.5 moles * 2  = 5 moles of H

Mass of N = 92.0 g/46 g/mol = 2 moles * 1 = 2  moles of N

Dividing through by the lowest mole ratio;

1/1, 5/1, 2/1

1 : 5 : 2

Hence the empirical formula is;
