Concept explainers
Name the following compounds:
Interpretation:
The names the of given compounds are to be identified from the formula.
Concept introduction:
Steps for naming the ionic compounds are as follows:
Identify the cation and the anion in the compound.
Combine the names of the cations and the anions by elimination of the word ‘ion’ from the names of the individual ions.
Steps for naming the binary molecular compounds are as follows:
First name the element that appears first in its molecular formula.
Now, name the second element by changing its ending to –ide.
Use proper prefixes to indicate the number of atoms present for individual elements.
Steps for naming the acids are as follows:
From hydrogen, omit the term ‘–gen’, leaving the name hydro-.
The name ending with ‘–ide’ is changed to ‘–ic’.
Now, combine the two terms and add the word acid to give complete name.
The oxoacids are named according to the names of the oxoanions from which they are derived. The acid based on an -ate ion is called –ic acid.

- Chlorine exists mainly as two isotopes, 37Cl and 33Cl. Which is more abundant? How do you know?arrow_forward3.116 The simplest approximate chemical formula for the human body could be written as C728H4850O1970N104Ca24P16K4S4Na3Cl2Mg. Based on this formula, describe how you would rank by mass the ten most abundant elements in the human body.arrow_forwardhe vigorous reaction between aluminum and iodine gives the balanced equation: :math>2Al(s)+3I2(s)2AlI2(s). mg src=Images/HTML_99425-9-2QAP_image001.jpg alt="" align="top"/> at do the coefficients in this balanced chemical equation tell us about the proportions in which these substances react on a macroscopic (mole) basis?arrow_forward
- The element bromine is Br2, so the mass of a Br2 molecule is the sum of the mass of its two atoms. Bromine has two isotopes. The mass spectrum of Br2 produces three peaks with relative masses of 157.836, 159.834, and 161.832, and relative heights of 6.337, 12.499. and 6.164, respectively. (a) What isotopes of bromine are present in each of the three peaks? (b) What is the mass of each bromine isotope? (c) What is the average atomic mass of bromine? (d) What is the abundance of each of the two bromine isotopes?arrow_forwardGallium arsenide, GaAs, has gained widespread use in semiconductor devices that convert light and electrical signals in fiber-optic communications systems. Gallium consists of 60.% 69Ga and 40.% 71Ga. Arsenic has only one naturally occurring isotope, 75As. Gallium arsenide is a polymeric material, but its mass spectrum shows fragments with the formulas GaAs and Ga2As2. What would the distribution of peaks look like for these two fragments?arrow_forwardGiven that the density of argon is 1.78 g/L under standard conditions of temperature and pressure, how many argon atoms are present in a room with dimensions 4.0 m 5.0 m 2.4 m that is filled with pure argon under these conditions of temperature and pressure?arrow_forward
- Atomic masses are relative masses. What does this mean?arrow_forwardThe density of a mixture of gases may be calculated by summing the products of the density of each gas and the fractional volume of space occupied by that gas. (Note the similarity to the calculation of the molar mass of an element from the isotopic masses and fractional abundances.) Assume dry air with CO2 removed is 20.96% (by volume) oxygen. 78.11% nitrogen, and 0.930% argon. Determine the density of argon.arrow_forwardGive the chemical formula for (a) chlorite ion, (b) chlorideion, (c) chlorate ion, (d) perchlorate ion, (e) hypochlorite ion.arrow_forward
