A chemist measures the energy change ?H during the following reaction: 2HgO (s) ?2Hg (l) +O2 (g) =?H182.kJ Use the information t
Elan Coil [88]

Answer:

A. endothermic.

A. Yes, absorbed.

Explanation:

Let's consider the following thermochemical equation.

2 HgO(s) ⇒ 2 Hg(l) + O₂(g)  ΔH = 182 kJ

The enthalpy of the reaction is positive (ΔH > 0), which means that the reaction is endothermic.

182 kJ are absorbed when 2 moles of HgO react (molar mass 216.59 g/mol). The heat absorbed when 72.8 g of HgO react is:

72.8g.\frac{1mol}{216.59g} .\frac{182kJ}{2mol} =30.6kJ/mol

Atoms are made up of protons, neutrons, and electrons.

Energy can be neither created nor destroyed.

Water freezes at 0°C

If  a piece of platinum is placed in acid, it will not react.

<h3>What are the correct pairing of the given terms?</h3>

The correct pairing of the given terms are obtained from the given options as follows:

Atoms of elements contains three sub-atomic particles which are protons, neutrons, and electrons.

Energy is the ability to do work.

According to the law of conservation of energy, Energy can be neither created nor destroyed.

Water is a liquid which freezes at 0°C.

Therefore, Water freezes at 0°C.

Platinum is a metal which is less reactive than hydrogen, Hence, it cannot displace hydrogen from acids.

Hence, if a piece of platinum is placed in acid, it will not react.

In conclusion, the correct pairing gives the correct description of the properties of the given terms.
