Concept explainers
(a)
Interpretation:
The volume of air in liters that might inhale while sleeping for 7.5 hours has to be calculated.
Concept Introduction:
Volume is the amount of space occupied by the matter.
The unit of volume is expressed in milliliters
(a)
Explanation of Solution
Assume each breath has a volume of about
The volume of air in liters can be calculated as:
The volume of air in liters that might inhale while sleeping for 7.5 hours is
Therefore, breathing is exposed to a large volume of air.
(b)
Interpretation:
Five things that improve the quality of air have to be given.
Concept Introduction:
Quality of air refers to a condition in which air in the surrounding. Good air quality refers to the condition of air with less pollution, clear air and free from smog.
(b)
Explanation of Solution
Quality of air refers to a condition in which air in the surrounding. Good air quality refers to the condition of air with less pollution, clear air and free from smog.
Five things that improve the quality of air is,
- • Burning of wood, vegetation, fuels etc should be reduced.
- • Low emission paints which pollute less have to be used.
- • Vehicles with good silencer have to be used.
- • Residential areas can improve the air quality by regular cleaning of carpets etc.
- • Proper treatment before the emission of gases from the industries.

- What is the preferable period of time to soak the apparatus with acid? Some said it is preferably overnight while other said it can be as longer as we want, maybe 3-4 days. Can anyone help to explain the concept?arrow_forwardConvert 1335 mm Hg to Paarrow_forwardPropane, C3H8, is a hydrocarbon that is commonly used as a fuel. (a) Write a balanced equation for the complete combustion of propane gas. (b) Calculate the volume of air at 25 C and 1.00 atmosphere that is needed to completely combust 25.0 grams of propane. Assume that air is 21.0 percent O2 by volume. (Hint: we will see how to do this calculation in a later chapter on gasesfor now use the information that 1.00 L of air at 25 C and 1.00 atm contains 0.275 g of 2 per liter.) (c) The heat of combustion of propane is 2,219.2 kJ/mol. Calculate the heat of formation, Hf of propane given that Hf of H2O(l)=285.8 kJ/mol and Hf of CO2(g)=393.5 kJ/mol. (d) Assuming that all of the heat released in burning 25.0 grams of propane is transferred to 4.00 kilograms of water, calculate the increase in temperature of the water.arrow_forward

You know that the temperature might get as low as 30. C, and you want to protect about 4.0 L water in the toilet tank from freezing. Calculate the volume of ethylene glycol (density = 1.113 g/mL; molar mass = 62.1 g/mol) you should add to the 4.0 L water.arrow_forward58 Magnesium will burn in air to form both Mg3N2 and MgO. What mass of each product would be found if burning a 3.11-g sample of magnesium to completion produces a combined total of 5.09 g of the two products?arrow_forward
