Problem 47E

Which statements about subatomic particles are true?

a.        If an atom has an equal number of protons and electrons, it will be charge-neutral.

b.        Electrons are attracted to protons.

c.        Electrons are much lighter than neutrons.

d.        Protons have twice the mass of neutrons.

Step-by-Step Solution:
Step 1 of 3

Solution : Here, we have to write the molecular and empirical formulas for the compounds. So first let’s see what is an empirical formula and molecular formula and let’s write the formulas. In chemistry, the empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound. The smallest whole number ratios of the subscripts of molecular formula are derived by dividing the subscripts by largest common factor. For example: the e mpiri cal formula of disulfur dioxide is S 2O2. the e mpir ical formula of ethane(C H ) will be CH . 2 6 3 Empirical formula gives the relative num ber of atoms of each kind present in that compound. For example: Consider, Ethane (C H ) 2 6 Relative number of atoms in simplest form will be CH and it is the empirical formula of 3 ethane. Molecular formula is a chemical formula that gives the total number of atoms of each element in each molecule of a substance. These definite numbers of atoms present in a molecule are rep resented as s ubscripts in the molecular formula. For Example : C H 2 t6 molecular formula of ethane. 1 molecule of ethane contains 2 atoms of Carbon a nd 6 hydrogen (H) atoms. Now,let’s find the molecular and empirical formulas for the compounds given : (1) Molecular formula : In the above compound,...
