Calculate the specific heat capacity for a 15.3-g sample of gold that absorbs 87.2 J when its temperature increases from 35.0 °C
diamong [38]

Answer:

The specific heat of gold is 0.129 J/g°C

Explanation:

Step 1: Data given

Mass of gold  = 15.3 grams

Heat absorbed = 87.2 J

Initial temperature = 35.0 °C

Final temperature = 79.2 °C

Step 2:

Q = m*c*ΔT

⇒ Q =the heat absorbed = 87.2 J

⇒ m = the mass of gold = 15.3 grams

⇒ c = the specific heat of gold = TO BE DETERMINED

⇒ ΔT = The change in temperature = T2 - T1 = 79.2 - 35.0 = 44.2 °C

87.2 J = 15.3g * c * 44.2°C

c = 87.2 / (15.3 * 44.2)

c = 0.129 J/g°C

The specific heat of gold is 0.129 J/g°C

When aqueous solutions of magnesium nitrate and sodium carbonate are mixed together what will happen
Bingel [31]

When sodium carbonate and magnesium nitrate solutions are combined, a precipitate is created as a result of a double-displacement process. As you balance the chemical equation, make predictions about the reaction's byproducts.

<h3>What occurs when magnesium sulfate and sodium carbonate are combined?</h3>

A solid may form when the solutions of two soluble salts are combined. Salts that are insoluble are created during precipitation processes. When magnesium sulfate and sodium carbonate are combined, magnesium carbonate, an insoluble salt, results.

<h3>What happens when hydrochloric acid and sodium carbonate interact?</h3>

What takes place when sodium carbonate and hydrochloric acid interact? When sodium carbonate is added to hydrochloric acid, a double displacement reaction takes place, resulting in the formation of sodium chloride, water, and carbon dioxide. The sodium carbonate and the two moles of HCl combine to generate carbonic acid.
