Answer:

2C₄H₁₀ + 13O₂ ⇒ 8CO₂ + 10H2₀

<h2>What is combustion? </h2>

The reaction of a substance with oxygen, producing one or more oxides, heat and light.

Butane (C₄H₁₀) is a hydrocarbon ( The name used for a hydrocarbon with four carbon atoms and only single bonds.) Butane consists of carbon and hydrogen and thus when it combust, it produces carbon dioxide and water.

2C₄H₁₀ + 13O₂ ⇒ 8CO₂ + 10H2₀

The following chemical equation follow the law of conservation of mass.

The law of conservation of mass states that in a closed system, mass is neither created nor destroyed during a chemical or physical reaction. The law of conservation of mass is applied whenever you balance a <u>chemical equation</u>. It is also applicable to stoichiometry. On the product side, the number of atoms must match the total of atoms on the product side. As a result, the equation must be balanced.

Which of these charges has the greatest magnitude

Natalka [10]

Answer:

magnitude means absolute value, so the one that is greastest, like |-7| and |4| even id |-7| is a negative number, but it is still the one farthest away from 0, so |-7| is greater than |4|.

That is the way to find the greatest magnitude, but because I don't know your numbers so I can not answer your question, but this is the way to solve for it.

Lead(II) nitrate is added slowly to a solution that is 0.0800 M in Cl− ions. Calculate the concentration of Pb2+ ions (in mol /

barxatty [35]

Answer:

$[Pb^{2+}]=3.9 \times 10^{-2}M$

this is the concentration required to initiate precipitation

Explanation:

$PbCl_2$ ⇄ $Pb^{2+}+2Cl^-$

Precipitation starts when ionic product is greater than solubility product.

Ip>Ksp

Precipitation starts only when solution is supersaturated because solution become supersaturated then it does not stay in this form and precipitation starts itself only solution become saturated.

This usually happens when two solutions containing separate sources of cation and anion are mixed together and here also we are mixing lead (||)nitrate solution(source of lead(||)) into the Cl- solution.

$Ip=[Pb^{2}][2Cl^-]^2=Ksp$

$Ksp=2.4\times 10^{-4}$

lets solubility=S

$[Pb^{2+}] = S$

$[Cl^-]=2S$

$Ksp=[Pb^{2+}]\times [Cl^-]^2$

$Ksp=S \times (2S)^2$

$Ksp=4S^3$

$S=\sqrt[3]{\frac{Ksp}{4} }$

$S=3.9\times 10^{-2}$

$[Pb^{2+}]=3.9 \times 10^{-2}M$ this is the concentration required to initiate precipitation

In ____________ reactions, certain molecules are broken down; in the process they release energy which is captured when high-ene

Rudik [331]

Answer:

Exergonic ,Endergonic,low concentration area,high

Explanation:

In exergonic reaction,certain molecules are broken down;in the process they release energy which is captured when high energy molecules(such as ATP and NADH) are formed.

The breakdown of these molecules can be coupled to thermodynamically unfavorable processes such as Endergonic reactions or pumping og hydrogen ion from low concentration areas to high concentration areas.

Melted candle wax has no fixed shape, but it does have a fixed volume. So, melted candle wax is a

dlinn [17]

It is a liquid because when you have a liquid, there is no definite shape. Therefore, this would be the answer because it takes the shape of its container.

Final answer: a. Liquid
