The answer is option 2 , the smallest whole-number coefficients, the coefficient of Pb²⁺ will be 2.

What is a Balanced Chemical Equation ?

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.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

There are two types of numbers that appear in chemical equations.

There are subscripts, which are part of the chemical formulas of the reactants and products;

and there are coefficients that are placed in front of the formulas to indicate how many molecules of that substance is used or produced.

Balance The Equation:

Pb²⁺ + Au²⁺ = Pb⁴⁺ + Au

Label Each Compound With a Variable

Label each compound with a variable to represent the unknown coefficients.

aPb²⁺ + bAu²⁺ = c Pb⁴⁺ + d Au

Create a System of Equations

Create an equation for each element where each term represents the number of atoms of the element in each reactant or product.

Pb: 2a + 0b = 4c + 0d

Au: 0a + 2b = 0c + 1d

e: 0a + -1b = -1c + 0d

2a - 4c = 0

2b - 1d = 0

-1b + 1c = 0

Solve For All Variables

Use substitution,

Substitute Coefficients and Verify Result

2Pb²⁺ + Au²⁺ = Pb⁴⁺ + 2 Au

So the answer is 2 , option 2

Convert 75 mL of water to gallons (show work)

lina2011 [118]

Answer:

$\huge\boxed{\sf 75\ mL = 0.02\ gallons}$

Explanation:

1 mL = 0.000264 gallons

<em><u>Multiplying both sides by 75</u></em>

75 mL = 0.000264 * 75 gallons

<h2>75 mL = 0.02 gallons</h2>

<u>Answer:</u> The given isotope of tin has 50 protons and 69 neutrons.

<u>Explanation:</u>

Atomic number is defined as the number of protons or number of electrons that are present in neutral atom. It is represented as Z.

Atomic number = Number of protons = Number of electrons

Mass number is defined as the sum of number of protons and number of neutrons. It is represented as A.

Mass number = Number of protons + Number of neutrons

We are given:

An isotope having representation $_{50}^{119}\textrm{Sn}$

Mass number of Sn = 19

Atomic number = 50

Number of neutrons = Mass number - Atomic number = 119 - 50 = 69

Hence, the given isotope of tin has 50 protons and 69 neutrons.
