Chapter 1, Problem 1.63E

Zinc ore (zinc sulfide) is treated with sulfuric acid, leaving a solution with some undissolved bits of material and releasing hydrogen sulfide gas. If 10.8 g of zinc ore is treated with 50.0 mL of sulfuric arid (density 1.153 g/mL), 65.1 g of solution and undissolved material remains. In addition, hydrogen sulfide (density 1.393 g/L) is evolved. What is the volume (in liters) of this gas?

Use the figure below to answer the following questions. a. Derive the relationship between C and X. b. If the temperature outside is 22.0C, what is the temperature in units of X? c. Convert 58.0X to units of C, K, and F.

What is density? Give two examples of possible units for density.

Indicate to what decimal position readings should be estimated and recorded nearest 0.1,0.01,etc. for measurements made with the following devices: a. A ruler with a smallest scale marking of 0.1cm b. A measuring telescope with a smallest scale marking of 0.1mm c. A protractor with a smallest scale marking of 1 d. A tire pressure gauge with a smallest scale marking of 1lb/in2.

A Different civilization on a distant planet has developed a new temperature scale based on ethyl alcohol. The freezing point of ethyl alcohol (117C) is designated as 0J, and its boiling point (78C) is designated as 100J. Assuming that the relationship between C and J is linear, (a) draw a graph of the line using the data above. (b) what is the slope of the line? (c) what is the y-intercept of the line? (d) Write an equation to convert J to C.

The “Chemistry in Focus” segmentTiny Thermometersstates that the temperature range for the carbon nanotube gallium thermometers is 50 °C to 500 °C. a. What properties of gallium make it useful in a thermometer? b. Determine the useful temperature range for the gallium thermometer in Fahrenheit units.

Make the conversion indicated in each of the following: the length of a soccer field, 120 m (three significant figures), to feet the height of Mt. Kilimanjaro, at 19,565 ft the highest mountain in Africa, to kilometers the area of an 8.5 × 11-inch sheet of paper in cm2 the displacement volume of an automobile engine, 161 in.3, to liters the estimated mass of the atmosphere, 5.61015 tons, to kilograms the mass of a bushel of rye, 32.0 lb, to kilograms the mass of a 5.00-grain aspirin tablet to milligrams (1 grain = 0.00229 oz)

Say you live in a climate where the temperature ranges from 100F to 20F and you want to define a new temperature scale, YS (YS is the Your Scale temperature scale), which defines this range as 0.0YS to 100.0YS. a Come up with an equation that would allow you to convert between F and YS. b Using your equation, what would be the temperature in F if it were 6.6YS?
