The butter contains a new arrangement of atoms. It’s a physical change therefore it cannot change into a different substance and it can turn into a solid again as physical changes just the property of a substance. The butter also remains as butter so there would still be the same number of atoms.

Why did we have you determine the reaction rate using reactant consumed per unit of time instead of product formed per unit of t
Vsevolod [243]

Answer:Rate of reaction can be determined in terms of concentration of reactants consumed or concentration of product formed per unit time

Explanation: For the reaction below

A ===>B

The reactant is A while the product given is B.

Reaction rate = Δ[B]/Δt = -Δ[A]/Δt

The concentration of A will decrease with time while the concentration of B will increases with time.

The negative sign in -Δ[A]/Δt is to convert the expression to positive since the change will always be negative (decreases)

In the reaction mg 2hcl right arrow. mgcl2 h2 which element’s oxidation number does not change? cl mg h
netineya [11]

The correct answer is Cl.

Chlorine is a substance that's employed in industry and is present in a number of household goods. There are times when chlorine takes the form of toxic gas. Chlorine gas can be converted into a liquid by applying pressure and cooling so that it can be transported and stored. The term "oxidation number" refers to the number of electrons that an element's atom either loses or gains during the production of a compound. The charge that an atom seems to have when forming ionic connections with other heteroatoms is used to define an atom's oxidation number. Even if it develops a covalent bond, an atom with a higher electronegativity is given a negative oxidation state.
