Concept explainers
(a)
Interpretation:
The number of protons, neutrons and electrons present in the atom of nitrogen-15 has to be given.
Concept Introduction:
Mass number is the sum of the number of protons and neutrons inside the nucleus of an atom. This gives the number of subatomic particle present inside the nucleus. Mass number is represented by the symbol A.
From atomic number and mass number, the number of each sub atomic particle can be found.
Complete chemical symbol notation can be given as.
An element is a pure substance that cannot be broken by ordinary
(b)
Interpretation:
The number of protons, neutrons and electrons present in the atom of iron-56 has to be given.
Concept Introduction:
Refer part (a).

Chemical Principles: The Quest for Insight
- Given 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_forwardThe present average concentration (mass percent) of magnesium ions in seawater is 0.13%. A chemistry textbook estimates that if 1.00 × 108 tons Mg were taken out of the sea each year, it would take one million years for the Mg concentration to drop to 0.12%. Do sufficient calculations to either verify or refute this statement. Assume that Earth is a sphere with a diameter of 8000 mi, 67% of which is covered by oceans to a depth of 1 mi, and that no Mg is washed back into the oceans at any time.arrow_forwardChlorine exists mainly as two isotopes, 37Cl and 33Cl. Which is more abundant? How do you know?arrow_forward
- 3.117 For the oxides of iron, FeO, Fe2O3, and Fe3O4, describe how you would determine which has the greatest percentage by mass of oxygen. Would you need to look up any information to solve this problem?arrow_forward4.104 When 2.750 g of the oxide Pb3O4 is heated to a high temperature, it decomposes to produce 0.0640 g of oxygen gas and 2.686 g of some new lead oxide compound. How can you use these data to determine the formula of the new compound?arrow_forwardMany cereals are made with high moisture content so that the cereal can be formed into various shapes before it is dried. A cereal product containing 58% H2O by mass is produced at the rate of 1000. kg/h. What mass of water must be evaporated per hour if the final product contains only 20.% water?arrow_forward
- 4-102 Aspartame, an artificial sweetener used as a sugar substitute in some foods and beverages, has the molecular formula C14H18N2O5. (a) How many mg of aspartame are present in 3.72 × 1026 molecules of aspartame? (b) Imagine you obtain 25.0 mL of aspartame, which is known to have a density of 1.35 g/mL. How many molecules of aspartame are present in this volume? (c) How many hydrogen atoms are present in 1.00 mg of aspartame? (d) Complete the skeletal structure of aspartame, where all the bonded atoms are shown but double bonds, triple bonds, and/or lone pairs are missing. (e) Identify the various types of geometries present in each central atom of aspartame using VSEPR theory. (f) Determine the various relative bond angles associated with each central atom of aspartame using VSEPR theory. (g) What is the most polar bond in aspartame? (h) Would you predict aspartame to be polar or nonpolar? (i) Is aspartame expected to possess resonance? Explain why or why not. (j) Consider the combustion of aspartame, which results in formation of NO2(g) as well as other expected products. Write a balanced chemical equation for this reaction. (k) Calculate the weight of C02(g) that can be prepared from 1.62 g of aspartame mixed with 2.11 g of oxygen gas.arrow_forward4.106 An ore sample with a mass of 670 kg contains 27.7% magnesium carbonate, MgCO3. If all of the magnesium carbonate in this ore sample is decomposed to form carbon dioxide, describe how to determine what mass of CO2 is evolved during the process.arrow_forwardA mixture of Fe2O3, and FeO was found to contain 72.00% Fe by mass. What is the mass of Fe2O3 in 0.750 g of this mixture?arrow_forward
