Here is a simple example. The inhabitants of a small island begin exporting beautiful cloth made from a rare plant that grows only on their island. Seeing how popular the small quantity that they export has been, they steadily raise their prices. A clothing maker from New York, thinking that he can save money by "cutting out the middleman," decides to travel to the small island and buy the cloth himself. Ignorant of the local custom of offering strangers outrageous prices and then negotiating down, the clothing maker accepts (much to everyone's surpise) the initial price of 400 tepizes/m². The price of this cloth in New York is 120 dollars/yard². Part A If the clothing maker bought 500 m² of this fabric, how much money did he lose? Use 1 tepiz = 0.625 dollar and 0.9144 m = 1 yard.

A gas at an initial pressure of 8.6x10° Pa undergoes expansion at constant temperature to 7.86x10° Pa. If the initial volume of the gas is 102 m³, what is the final volume (in m³) after the expansion process? (Leave your answer in 1 decimal place. Do not type in the units.)
The recommended daily caloric intake is 2000 calories (8,400,000J). This is because this is the same value for how much the average body loses to heat and work in a typical day (your change in energy is zero because you take in the same amount of energy you lose). A) If you lose a total of 8,400,000J (Qout+W=total lost), but consume 1200 calories of food (5,000,000J), what would your change in energy be? B) Assuming your change in energy is negative (hint-it should be), where does your body get the extra energy to maintain it's temperature?
We turn on a heater that delivers 150 watts (150 J/s) to 1.9 kg of water in a lab experiment. After 33 seconds, how much will the water temperature have increased? Give your answer in degrees Celsius. Hint: The specific heat of water is 4186 J/kg °C.
You can make electricity to run a clock by inserting two electrodes into an orange. How does it work? The energy that came from photosynthesis is slowly converted into electricity. The acid in the orange provides the energy. The living cells from the orange weakly make electricity. The orange acts as the salt bridge; the electrodes are two different metals.
A particular extension cord can support up to 8 amps. Martino has an iron whose label states 720 watts, and he wonders if the iron can be plugged into the extension cord. If watts are converted to amps by dividing by 144, how many amps does the iron use? 14 amps 18 amps 5 amps 90 amps
A person eats an 408.85 J snack before working out. If a person uses all of their eaten energy to lift a 10.36 kg weight. How high can they lift the weight?
QUESTION 7 (Start on a new page.) The airbags in motor vehicles contain the compound sodium azide (NaNs). When a car crashes into an object, the compound decomposes and the nitrogen inflates the airbag. The balanced equation for the reaction is as follows: NaN(s) → 2Na(s) + 3N2(g) In one such decomposition, 2,53 x 10° molecules of nitrogen are generated. Calculate the: 7.1 Number of moles of NaN(s) that decomposed 7.2 Volume of N2(g) produced Assume that the reaction occurs at standard pressure. QUESTION 8 (Start on a new page.) Aluminium sulphate is used as a coagulant in water purification. It reacts with sodium hydroxide to form aluminium hydroxide which drags the impurities as it settles. The balanced equation for the reaction is: Al2(SO4)3(aq) + 6NaOH(aq) → 2Al(OH)3(s) + 3Na2SO4(aq) A chemist at a water purification plant adds 700 g of Al2(SO4)3 to a sample of water. 8.1 Calculate the maximum mass of Al(OH)3 that can be produced from this mass of Al2(SO4)3.
