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

How is a comet different from a star?

lana [24]

Answer:

The main difference between asteroids and comets is their composition, as in, what they are made of. Asteroids are made up of metals and rocky material, while comets are made up of ice, dust and rocky material. Both asteroids and comets were formed early in the history of the solar system about 4.5 billion years ago.

Which isomer of 1-bromo-2-tert-butylcyclohexane reacts faster when refluxed with potassium tert-butoxide?Draw the structure of t

ivolga24 [154]

Answer:

See explanation and image attached

Explanation:

The reaction of 1-bromo-2-tert-butylcyclohexane with potassium tert-butoxide is an elimination reaction that occurs by E2 mechanism.

The E2 reaction proceeds faster when the hydrogens are in an antiperiplanar position at an angle of 180 degrees.

This is only attainable in the trans isomer of 1-bromo-2-tert-butylcyclohexane. Hence trans 1-bromo-2-tert-butylcyclohexane reacts faster with potassium tert-butoxide
