Answer:-

86.794 K

Explanation:-

Initial temperature T 1 = 32 C + 273 = 305 K

Initial Pressure P 1 = 49.9 KPa

New Pressure P 2 = 14.2 KPa

The Volume remains same since it is rigid.

∴V 1 = V 2 = 50.0 L

Using the relation

P 1 V 1 / T1 = P 2 V 2 / T 2

New temperature T 2 = P 2 V 2 T 1 / ( P 1 V 1)

= 14.2 KPa x 50.0 L x 305 K / ( 49.9 KPa x 50.0 L)

= 86.794 K

What’s the reaction type of aqueous magnesium sulfate + aqueous sodium carbonate?
IrinaK [193]

Answer: Double displacement reaction

Explanation:

Double displacement reaction is defined as the reaction where exchange of ions takes place.

The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The chemical reaction between aqueous magnesium sulfate and aqueous sodium carbonate is represented as:

MgSO_4(aq)+Na_2CO_3(aq)\rightarrow Na_2SO_4(aq)+MgCO_3(s)
