Step by step solution

01

Defining the element, compound, and mixture

An element is a pure substance that cannot be broken into simpler substances by chemical reaction.

A compound is defined as a substance divided into atoms, molecules, or ions by any chemical process.

While a mixture is a combination of two or more substances which can be separated by physical process.

02

Classifying the above components into the elements, compounds, or mixture

  1. Iron is an element.
  2. Oxygen is anelement.
  3. Mercury oxide is acompound.
  4. Pancake syrup is amixture.
  5. Carbon dioxide is acompound.
  6. A substance composed of molecules, each containing one hydrogen atom and one chlorine atom, is acompound.
  7. Baking soda is acompound.

A 500-mL bottle of water at room temperature and a 2-L bottle of water at the same temperature were placed in a refrigerator. After 30 minutes, the 500-mL bottle of water had cooled to the temperature of the refrigerator. An hour later, the 2-L of water had cooled to the same temperature. When asked which sample of water lost the most heat, one student replied that both bottles lost the same amount of heat because they started at the same temperature and finished at the same temperature. A second student thought that the 2-L bottle of water lost more heat because there was more water. A third student believed that the 500-mL bottle of water lost more heat because it cooled more quickly. A fourth student thought that it was not possible to tell because we do not know the initial temperature and the final temperature of the water. Indicate which of these answers is correct and describe the error in each of the other answers.

Write the symbol for each of the following ions: (a) the ion with a \(3 + \) charge, \(28\) electrons, and a mass number of \(71\)(b) the ion with \(36\) electrons, \(35\) protons, and \(45\) neutrons (c) the ion with \(86\) electrons, \(142\) neutrons, and a \(4 + \) charge (d) the ion with a \(2 + \) charge, atomic number \(38,\) and mass number \(87\)
