Otrada [13]3 years ago
3 0

Answer: Option A.

∆H is less than (more negative)∆ E of the system

Explanation:

From the question, a solid yield a mixture of gases in an exothermic reaction. Exothermic reaction is a process that give out energy after the reaction, it is mostly represented by negative H, that is enthalpy .

The enthalpy is negative( ∆H) when the reaction release energy meaning that the energy that must be absorbed to break the bonds of the reactants is greater than than energy released when new bonds are formed.

From the reaction more heat is released.

A gas occupies a volume of 202 ml at a pressure of 505 torr. To what pressure must the gas be subject in order to change the vol
UNO [17]

Answer:

1569 torr

Explanation:

Assuming ideal behaviour and constant temperature, we can solve this problem by using <em>Boyle's law</em>, which states:

  • V₁P₁ = V₂P₂

Where in this case:

  • V₁ = 202 mL
  • P₁ = 505 torr
  • V₂ = 65.0 mL
  • P₂ = ?

We <u>input the data given by the problem</u>:

  • 202 mL * 505 torr = 65.0 mL * P₂

And <u>solve for P₂</u>:

  • P₂ = 1569 torr

In the equation for the formation of magnesium sulfide shown, which atom gains electrons?
Zarrin [17]

S + 2e⁻ → S²⁻ (sulfur will gain electrons)

Mg - 2e⁻ → Mg²⁺ (magnesium will lose electrons)

Magnesium is a metal which tends to give electrons which are received by the sulfur, which is a nonmetal and tends to gain electrons.
