Concentrated nitric acid has a molarity of 15.9 M and a density of 1.42 g/mL. Calculate the following concentrations using 1.00 L of HNO3.
a) % by mass
b) molality
c) mole fraction
Answer: a) percent by mass = [tex]70.5\%[/tex]
b) molality = 38.01mol/kg
c) mole fraction = 0.40
Explanation:
Given molarity = 15.9 M
moles of [tex]HNO_3[/tex] = 15.9 moles in 1.00 L of solution
mass of [tex]HNO_3[/tex] = [tex]moles\times {\text {Molar mass}}=15.9mol\times 63g/mol=1001.7g[/tex]
Density of solution of = 1.42 g/ml
Volume of solution = 1.00 L = 1000 ml
Mass of solution = [tex]Density\times volume= 1.42g/ml\times 1000ml=1420g[/tex]
mass of solvent = mass of solution - mass of solute = (1420-1001.7) g = 418.3 g = 0.4183 kg
moles of solvent = [tex]\frac{\text {given mass}}{\text {Molar mass}}=\frac{418.3g}{18g/mol}=23.2mol[/tex]
percent by mass =[tex]\frac{\text {mass of nitric acid}}{\text {mass of solution}}\times 100=\frac{1001.2}{1420}\times 100=70.5\%[/tex]
molality = [tex]\frac{\text {no of moles of solute}}{\text {mass of solvent in kg}}=\frac{15.9mol}{0.4183kg}=38.01mol/kg[/tex]
mole fraction = [tex]\frac{\text {moles of solute}}{\text {total moles}}=\frac{15.9}{15.9+23.2}=0.40[/tex]

Warmer temperatures at the Earth's poles could change atmospheric circulation and wind patterns. Propose a solution for how communities near the poles can prepare for these changes in wind.
Warmer temperatures at the poles could alter wind patterns and atmospheric circulation.
What is atmospheric circulation?Through atmospheric circulation, heat is transferred over the surface of the Earth. This has an effect on the water cycle, including cloud formation and precipitation events. The movement of air masses determines our everyday weather, and long-term patterns in circulation have an impact on regional climate and ecosystems.
This pattern, called atmospheric circulation, is a result of the Earth being heated by the Sun more at the equator than in the poles. The rotation of the Earth has an effect on it as well. In the tropics, near the equator, warm air rises.
Atmospheric circulation, or the movement of heat and air over the earth's surface, is governed by Hadley, Ferrel, and polar cells.
Thus, Warmer temperatures at the poles could alter wind patterns.

Describe the process and results you used to determine the force exerted by the hockey stick on the puck.
Answer:
If you know the mass and can find the final speed of the puck, then you know how much impulse was applied to it. If you then take the known (from your video) period of time that the stick was contacting the puck, you can calculate the average force over that time.
If you want to get more sophisticated, you might be able to figure out the forces applied by looking at how the stick bends at any given instant, again from your video.

My topic is about spray irrigation and I want to know why do we do this with the spray irrigation
Answer and Explanation:
Spray irrigation is used because it allows water to reach the common soil with less impact, without stimulating soil compaction. In addition, this irrigation method promotes better water distribution, irrigation control, optimization of water volume, reduction of waste and better use of water by the plant. All of these benefits outweigh the high price of this type of irrigation and allow many people to prefer this irrigation over other less efficient methods.

Crude birth rate 38/1,000 individuals
Crude death rate 24/1,000 individuals
Net migration rate 2/1,000 individuals
(i) Calculate the national population growth rate for country X. Show your work.
(ii) Using the rule of 70, calculate the doubling time for this population.
Answer:
40-24 = 1616/1000 = 0.016 x 100 = 1.6% growth rate
70/1.6 = 43.75 years = doubling time.
The national population growth rate for country X is 1.6%
Crude birth rate = 38/1,000 individuals
Crude death rate = 24/1,000 individuals
Net migration rate = 2/1,000 individuals
The national population growth rate for country X will be:
= [(38 + 2) - 24] / 1000
= 16/1000
= 0.016
= 1.6% growth rate.
Using the rule of 70, the doubling time for this population will be:
= 70/1.6
= 43.75 years
Therefore, the doubling time for this population is 43.75 years.
