The total number of protons are 6 and the total number of neutrons are 7 in an atom of the naturally occurring carbon isotope with the largest mass number.

Isotopes of almost all elements save hydrogen get their names from the mass number of their nuclei. Carbon atoms, for instance, have a mass number of 12 since the sum of their six protons and six neutrons equal 12. As a result, these atoms are referred to as carbon-12. The atomic mass of carbon atoms with seven neutrons is 13, which is equal to six protons plus seven neutrons. The isotope known as carbon-13 can be found in these atoms.

The reaction of aluminum and hydrogen bromide will form 212.44 grams of aluminum bromide.

The chemical equation for the reaction between aluminum and hydrogen bromide is:

[tex]2 Al + 3 HBr[/tex] →[tex]Al_2Br_6[/tex]

From this equation, we can see that the reaction is a stoichiometric reaction, which means that the ratio of the reactants and products is fixed and is determined by the coefficients in the balanced equation.

If we have 121 grams of hydrogen bromide, the number of moles of hydrogen bromide can be calculated using the molar mass of hydrogen bromide ([tex]HBr[/tex]) which is approximately 80.9 g/mol. So:

121 g [tex]HBr[/tex] /  80.9 g/mol = 1.49 mol [tex]HBr[/tex]

Since the coefficient of hydrogen bromide in the balanced equation is 3, we know that for every one mole of aluminum, we need 3 moles of HBr. So, in this case, we have excess [tex]Al[/tex], which means the limiting reactant is [tex]HBr[/tex], and we have 1.49 moles of [tex]HBr[/tex].

The number of moles of aluminum bromide ([tex]Al_2Br_6[/tex]) formed can be calculated by dividing the number of moles of [tex]HBr[/tex] by the coefficient of [tex]HBr[/tex] in the balanced equation, which is 3

1.49 moles [tex]HBr[/tex] / 3 = 0.497 moles [tex]Al_2Br_6[/tex]

We can calculate the number of grams of aluminum bromide by multiplying the number of moles by the molar mass of aluminum bromide, which is approximately 427.3 g/mol

0.497 moles [tex]Al_2Br_6[/tex]  * 427.3 g/mol = 212.44 g [tex]Al_2Br_6[/tex]

So, the reaction of aluminum and hydrogen bromide will form 212.44 grams of aluminum bromide.

Answer:The moles of carbon dioxide produced from 100 g methane is 6 moles.

Explanation: Balanced Equation. CH4+2O2 → CO2+2H2O.

The combustion of 2.00 mol of [tex]CH_4[/tex] produces approximately 72.08 grams of [tex]H_2O.[/tex] All the options given are incorrect.

Combustion is a chemical reaction that occurs between a fuel and an oxidizing agent basically in presence of oxygen, typically producing heat and light.

To determine the mass of [tex]H_2O[/tex] produced by the combustion of 2.00 mol of [tex]CH_4[/tex], we need to use the stoichiometric ratio between [tex]CH_4[/tex]and [tex]H_2O[/tex] in the balanced chemical equation.

From the balanced equation: [tex]CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O[/tex]

We can see that for every 1 mole of [tex]CH_4[/tex], 2 moles of [tex]H_2O[/tex]are produced. We can see that for every 1 mole of [tex]CH_4[/tex], 2 moles of [tex]H_2O[/tex]are produced.

Given that we have 2.00 mol of [tex]CH_4[/tex], we can calculate the moles of [tex]H_2O[/tex]produced:

2.00 mol [tex]CH_4[/tex] × (2 mol [tex]H_2O[/tex]/ 1 mol [tex]CH_4[/tex]) = 4.00 mol [tex]H_2O[/tex]

Now, we can calculate the mass of [tex]H_2O[/tex]produced using the molar mass of water ([tex]H_2O[/tex]), which is approximately 18.02 g/mol:

Mass of [tex]H_2O[/tex] = Number of moles of [tex]H_2O[/tex]× Molar mass of [tex]H_2O[/tex]

Mass of [tex]H_2O[/tex] = 4.00 mol × 18.02 g/mol = 72.08 g

Therefore, the mass of [tex]H_2O[/tex] produced by the combustion of 2.00 mol of [tex]CH_4[/tex] is approximately 72.08 grams.

[ OH−] of a solution that is 0.300 M in HCO3− is 3.24×10^-8 Molarity. and the oh of the solution is 7 .49

Part A: We know that HCO3- is a weak base, so it can be converted to H2CO3 (carbonic acid) through the following equilibrium:

HCO3- + H2O <=> H2CO3 + OH-

The Ka1 for H2CO3 is 4.3×10^-7, so we can use the following expression to find the [OH-]:

[H2CO3][OH-] = Ka1 * [HCO3-]

[OH-] = Ka1 * [HCO3-] / [H2CO3]

Since [H2CO3] is equal to [HCO3-], we can simplify this to: [OH-] = Ka1 * [HCO3-]^2

[OH-] = (4.3×10^-7) * (0.300)^2[OH-] = Ka1 * [HCO3-]^2 [OH-] = (4.3×10^-7) * (0.300)^2

[OH-] = 3.24×10^-8 M. So the [OH-] of the solution is 3.24×10^-8 Molarity.

Part B: To find the pH of the solution, we need to find the negative log of the [OH-].

pH = -log([OH-])

pH = -log(3.24×10^-8)

pH = 7.49

So the pH of the solution is 7.49.

Matter can be broken down into two categories: pure substances and mixtures.

We are surrounded by matter, which is anything that takes up space and has mass. As matter, solids and liquids are more visible. The three states of matter most frequently encountered on earth are solids, liquids, and gases. A solid has a distinct shape and is unyielding. A liquid flows and conforms to a container, but when gravity acts on it, it creates a flat or slightly curved upper surface. A gas adopts the volume and shape of its container.

Elements and compounds are formed through the further division of pure substances. Physically coupled structures known as mixtures can be disassembled into their component parts.

A pure material is something that exclusively comprises one type of matter, according to the definition. Any sample of this substance that you examine must have exactly the same item, with a fixed, specific set of qualities. This might either be one single element or one single compound.
