Question: Using the data in Table 18 22 calculate the mass of
Using the data in Table 18.22, calculate the mass of argon at 25oC and 1.0 atm in a room 10.0 m × 10.0 m × 10.0 m. How many Ar atoms are in this room? How many Ar atoms do you inhale in one breath (approximately 2 L) of air at 25oC and 1.0 atm? Argon gas is inert, so it poses no serious health risks. However, if significant amounts of radon are inhaled into the lungs, lung cancer is a possible result. Explain the health risk differences between argon gas and radon gas.
Answer to relevant QuestionsFor the structures of the xenon compounds in Fig. 18.27, give the bond angles exhibited and the hybridization of the central atom in each compound. Figure 18.27 Diagonal relationships in the periodic table exist in addi-tion to the vertical relationships. For example, Be and Al are similar in some of their properties, as are B and Si. Rationalize why these diagonal relationships ...It takes 15 kWh (kilowatt-hours) of electrical energy to produce 1.0 kg of aluminum metal from aluminum oxide by the Hall–Heroult process. Compare this to the amount of energy necessary to melt 1.0 kg of aluminum metal. ...The unit cell for a pure xenon fluoride compound is shown below. What is the formula of the compound? Provide a reasonable estimate for the number of atoms in a 150-lb adult human. Use the information given in Table 18.2. Table 18.2
