7 0

Answer:

A reaction rate is a measure of how fast a reactant disappears or a product forms during a reaction.

Explanation:

It is usually defined as the change in concentration per unit time:

Δ(concentration)/Δt

The units are (moles per litre) per second.

In symbols, the units are mol/(L·s) or mol·L^-1 s^-1.

If you have 2.86 gallons of pure water, how many molecules of water are ionized at any given time ?
AleksandrR [38]

Answer:

The molar mass of water is 18 grams per mole. So in 18 grams of water, there are 6.02 x 1023 molecules.

One gallon of water is equal to 3.7854118 liters. If we assume that the water is at 4 °C (to keep things simple), the density of water is exactly 1 gram per milliliter, or 1 kilogram per liter. So 1 gallon of water at 4 °C weighs exactly 3.7854118 kilograms, or 3785.41118 grams.

If one mole of water weighs 18 grams, then there are 210.30 moles of water in a gallon. Since one mole of water is made up of 6.02 x 1023 molecules, in one gallon of water there are 1.266 x 1026 molecules.

That is: 126600000000000000000000000 molecules!

If we multiply that by the number of atoms in a single water molecule -- 3 atoms -- then we get:

379800000000000000000000000 atoms!

Definition of chemical change
yuradex [85]

Answer:

Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
