Answer:

A pure substance

Explanation:

Epsom salt is named after Epsom, the town in England where it was discovered. Epsom salt is an inorganic salt, Magnesium Sulfate, its formula is MgSO₄.

It is more commonly found in its heptahydrate state: MgSO₄·7H₂O. However the water (or hydration) refers only to the structure of its crystals, as such the hydrated salt is still considered a pure substance.

Write the overall, balanced molecular equation and indicate which element is oxidized and which is reduced for the following rea

galina1969 [7]

Answer:

Cd(s) + AgNO₃(aq) → Cd(NO₃)₂ (aq) + Ag(s)

Oxidized: Cd

Reduced: Ag

Explanation:

Cd(s) + AgNO₃(aq) → Cd(NO₃)₂ (aq) + Ag(s)

Cd → Cd²⁺ + 2e⁻ Half reaction oxidation

1e⁻ + Ag⁺ → Ag Half reaction reduction

Ag changed oxidation number from +1 to 0

Cd changed oxidation number from 0 to +2

Let's ballance the electrons

( Cd → Cd²⁺ + 2e⁻ ) .1

( 1e⁻ + Ag⁺ → Ag ) .2

Cd + 2e⁻ + 2Ag⁺ → 2Ag + Cd²⁺ + 2e⁻

Finally the ballance equation is:

Cd(s) + 2AgNO₃(aq) → Cd(NO₃)₂ (aq) + 2Ag(s)

Answer:

The new temperature will be 565.83 K.

Explanation:

Gay Lussac's law establishes the relationship between the temperature and the pressure of a gas when the volume is constant. This law says that the pressure of the gas is directly proportional to its temperature. This means that if the temperature increases, the pressure will increase; or if the temperature decreases, the pressure will decrease.

In other words, Gay-Lussac's law states that when a gas undergoes a constant volume transformation, the ratio of the pressure exerted by the gas temperature remains constant:

$\frac{P}{T} =k$
