Answer: Option (d) is the correct answer.

Explanation:

A substance which contains two or more different number of substances that are physically mixed together is known as a mixture.

For example, a mixture of air which contains oxygen, nitrogen and other gases.

Components of a mixture will always combine physically with each other.

A compound is defined as the substance in which different elements are chemically combined together in a fixed ratio by mass.

For example, NaCl is a compound and elements are present in 1:1 ratio.

A compound can be divided into its constituent or simpler substances.

Thus, we can conclude that difference between a compound and a mixture is that components of a mixture are not chemically bonded together.

Is table salt, NaCl, a typical ionic compound? Explain.
romanna [79]
Yes because Na is a metal and Cl is a nonmental, so they criss cross charges, as Na is 2+ and Cl is 2-, 2+ indicates that Na gives AWAY electrons to Cl and the 2- on Cl indicates it receiving electrons. NaCl is table salt and forms a crystal lattice structure, which is why salt is solid at room temperature.

The formula for magnesium chloride is MgCl2. How many magnesium atoms are there in one molecule?
Keith_Richards [23]
This is a trick question really, or at least the wording is poor chemistry. Molecules are the smallest unit of a simple covalent compound that retain the chemical properties of that compound. Covalent means there are bonds between atoms due to sharing a pair of electrons, and an example of such a compound is water, H2O. There are discrete H2O molecules moving past each other, with only weak intermolecular forces in between them.

Yet MgCl2 is not a covalent compound. In fact the bonding is ionic, meaning that electrons are transferred between the atoms to form positive and negative ions, which then electrostatically attract. Ionic compounds form a giant ionic lattice, a continuous structure of millions of these ions. An ionic molecule does not really exist.

What I assume is meant is the formula unit, a term very similar in meaning to a molecule. The difference is well shown by comparing empirical formula and molecular formula. A molecular formula shows how many of each atom are in a molecule, yet the empirical formula just shows the simplest whole-number ratio between the number of these atoms. Take ethane: the molecular formula is C2H6 and the empirical formula is CH3.

The ionic formula unit is like this empirical formula. By this standard the likely answer is A (1), because the formula shows that for every magnesium atom, there are two chlorine atoms.

I hope this helps :)
