The right answer is chlorofluorocarbons (CFCs).

A good aerosol propellant must be odorless, colorless and non-flammable. CFCs, chlorofluorocarbons, have been used for many years. Unfortunately, they would have actively participated in the destruction of the ozone layer. Their use was banned in 1985 by the Montreal Protocol. Other often flammable substitutes (for example butane or propane) have been found.

Amanda [17]

Answer:

The nucleus consists of 25 protons (red) and 30 neutrons (blue). 25 electrons (green) bind to the nucleus, successively occupying available electron shells (rings). Manganese is a transition metal in group 7, period 4, and the d-block of the periodic table. It has a melting point of 1246 degrees Celsius.

When magnesium chloride is formed what question will the student need to ask prior to writing the formula?

ivann1987 [24]

Prior to writing the chemical formula of magnesium chloride, a question which any student will need to ask is: A. What are the oxidation numbers of each atom?

A chemical formula can be defined as a scientific notation that is used to show (represent) the type and total number of atoms that constitute a particular chemical molecule or compound, by using the oxidation number, chemical symbols and subscripts.

Hence, a student would need to know the oxidation numbers of each atom when magnesium chloride is formed after a chemical reaction.

In Chemistry, an oxidation number represents the number of electrons gained or lost by an atom of a chemical element during a chemical reaction.

In conclusion, when magnesium chloride is formed, a question which the student will need to ask prior to writing the chemical formula is "what are the oxidation numbers of each atom?"

\al(s) + 3agno3(aq) → al(no3)3(aq) + 3ag(s) this equation represents which type of chemical reaction?

Savatey [412]

Al(s) + 2AgNO3(aq) = Al(NO3)3(aq) + 3 Ag (s)

is a single replacement reaction

A single replacement reaction is a type of chemical reaction were element react with a compound and the element take place of another element in that compound. In the reaction above Aluminium (Al) take the place of silver (Ag) from it compound.that is AgNO3. single replacement reaction is possible because aluminium is in high in reactivity series as compared to silver.
