An event planner accidentally leaves a tray of cupcakes in his car for several hours on a sunny day. When he returns, the former

ly firm frosting is now runny and wet to the touch. Which answer choice best describes what happened in this scenario? The particles of frosting released energy to their surroundings and changed from the solid to the liquid state. The particles of frosting released energy to their surroundings and changed from the liquid to the solid state. The particles of frosting absorbed energy from their surroundings and changed from the solid to the liquid state. The particles of frosting absorbed energy from their surroundings and changed from the liquid to the solid state.

Answer:

The particles of frosting absorbed energy from their surroundings and changed from the solid to the liquid state.

Explanation:

On a sunny day, the energy of the particles in the surrounding is higher than the energy of the frosting tray of cupcakes.

As a result of the exchange of energy between the tray of cupcakes and the surrounding, the tray of cupcakes absorbs energy from the surrounding. When this occurs, the firm frosting is now converted from solid to liquid which is runny and wet to touch, hence the answer above.

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such
8_murik_8 [283]

Answer:

0.0164 g

Explanation:

Let's consider the reduction of silver (I) to silver that occurs in the cathode during the electroplating.

Ag⁺(aq) + 1 e⁻ → Ag(s)

We can establish the following relations.

  • 1 A = 1 C/s
  • The charge of 1 mole of electrons is 96,468 C (Faraday's constant)
  • 1 mole of Ag(s) is deposited when 1 mole of electrons circulate.
  • The molar mass of silver is 107.87 g/mol

The mass of silver deposited when a current of 0.770 A circulates during 19.0 seconds is:

19.0s \times \frac{0.770c}{s} \times \frac{1mole^{-} }{96,468C} \times \frac{1molAg}{1mole^{-}} \times \frac{107.87g}{1molAg} = 0.0164 g
