<u>Answer:</u> The coefficient of carbon in the chemical reaction is 1.

<u>Explanation:</u>

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

The chemical equation for the reaction of tin (IV) oxide and carbon follows:

SnO_2+C\rightarrow Sn+CO_2

By Stoichiometry of the reaction:

1 mole of tin (IV) oxide reacts with carbon to produce 1 mole of elemental tin and carbon dioxide.

Hence, the coefficient of carbon in the chemical reaction is 1.

What is the pH of the solution at the endpoint of a titration
Arada [10]

Answer:

The pH at the equivalence point is 7.0.

Explanation:

This is because the solution only contains water and a salt that is neutral.

Since neither H+ or OH-, molecules remain in the solution.

We can conclude that the equivalence point is 7.0.

ohaa [14]

Answer:

Oxide of manganese, Potassium permanganate, Manganese bromide and manganese oxide.

Explanation:

1. Manganese dioxide

Its chemical formula is $MnO_2$. It is +4 oxidation state. It is a black solid which is fairly stable.

2. Potassium permanganate

Its chemical formula is $KMnO_4$. It is commonly used in the laboratories as oxidizing agent. They appear black in color.

3 Manganese bromide

Its chemical formula is $MnBr_2$

4. Oxides of manganese

Chemical formula is $Mn_3O_4$

The most stable state of Manganese is +2 oxidation state.

Question 6
jolli1 [7]

The molecular weight of the substance is 30.46 g/mol.

<h3>What is molar mass?</h3>

Molar mass can be defined as the mass is divided by the number of moles of the substance.

Step 1: calculating the moles

Given, the mass is 177 g

Pressure is 1.18 atm.

The volume is 2.30 L

By the formula of ideal gas

\rm PV = nrt\\1.18 \times 2.30 = n \times 8.312 \times 10^-^2 \times 19.0\\\\n = \dfrac{8.312 \times 10^-^2 \times 19.0}{1.18 \times 2.30} = 0.581 \;mol

Step2 -calculate the molecular weight

The moles are 0.581

\rm Molar\;mass = \dfrac{mass}{number\;of\;moles} \\\\\rm Molar\;mass = \dfrac{17.7g}{0.581} = 30.46

Thus, the molecular weight is 30.46 g/mol

Which atom has the weakest attraction for electrons in a chemical bond?(1) a boron atom (3) a fluorine atom(2) a calcium atom (4
BARSIC [14]
The (2) calcium atom, because when looking at the periodic table, we see that the calcium atom is in a location where according to the periodic table, has the lower electronegativities in respect to the other three choices. We see that it also has a lower electronegativity value than the others. Electronegativity is the attraction constant for the electrons in a chemical bond. The higher the electronegativity, the higher the attraction of the electrons. Fluorine has the highest electronegativity with 4.0.
