Concept explainers
(a)
Interpretation:
The electronic configuration for valence electrons of boron has to be given.
Concept Introduction:
Aufbau’s principle:
Aufbau’s principle states that electrons are filled into atomic orbitals in the increasing order of orbital energy level. According to the Aufbau principle the available atomic orbitals with the lowest energy levels are occupied before those with higher energy levels.
(b)
Interpretation:
The electronic configuration of Nitrogen has to be given.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
The electronic configuration of Sodium has to be given.
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
The electronic configuration of Chlorine has to be given.
Concept Introduction:
Refer to part (a).

- Given that a sample of air is made up of nitrogen, oxygen, and argon in the mole fractions 0.78 N2, 0.21 O2, and 0.010 Ar, what is the density of air at standard temperature and pressure?arrow_forwardGiven that a sample of air is made up of nitrogen, oxygen, and argon in the mole fractions 0.78 N2, 0.21 O2, and 0.010 Ar, what is the density of air at standard temperature and pressure?arrow_forward5-33 A certain quantity of helium gas is at a temperature of 27 °C and a pressure of 1.00 atm. What will the new temperature be if its volume is doubled at the same time that its pressure is decreased to one-half its original value?arrow_forward
- 5-114 Carbon dioxide gas, saturated with water vapor, can be produced by the addition of aqueous acid to calcium carbonate based on the following balanced net ionic equation: (a) How many moles of wet CO (g), collected at 60.°C and 774 torr total pressure, are produced by the complete reaction of 10.0 g of CaCO3 with excess acid? (b) What volume does this wet CO2 occupy? (c) What volume would the CO2 occupy at 774 torr if a desiccant (a chemical drying agent) were added to remove the water? The vapor pressure of water at 60.°C is 149.4 mm Hg.arrow_forward109 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 volume of CO2 is evolved during the process. What would have to be measured to predict the needed volume in advance?arrow_forwardPlot the data given in Table 5.3 for oxygen at 0C to obtain an accurate molar mass for O2. To do this, calculate a value of the molar mass at each of the given pressures from the ideal gas law (we will call this the apparent molar mass at this pressure). On a graph show the apparent molar mass versus the pressure and extrapolate to find the molar mass at zero pressure. Because the ideal gas law is most accurate at low pressures, this extrapolation will give an accurate value for the molar mass. What is the accurate molar mass?arrow_forward
