- The German chemist Fritz Haber proposed paying off the reparations imposed against Germany after World War I by extracting gold from seawater. Given the following data, what was the dollar amount of the gold that could have been extracted from 3.0 m3 of seawater? The price of gold at the time was $0.68 per gram of gold. Gold occurs in seawater to the extent of 5.15 x 1011 atoms per gram of seawater. The density of seawater is 1.03 g/cm3.arrow_forwardThe density of water is approximately 1 g/cm³. Which of these substances will sink in water? A) Liquid hydrogen, d = 0.070 g/cm³ B) Lithium, d = 0.535 g/cm³ C) Potassium, d = 0.860 g/cm³ D) Polymer resin, d = 1.03 g/cm³arrow_forwardAs part of a science project, you study traffic patterns in your city at an intersection in the middle of downtown. You set up a device that counts the ears passing through this intersection for a 24-hr period during a weekday. The graph of hourly traffic looks like this. a. At what time(s) does the highest number of cars pass through die intersection? b. At what time(s) does the lowest number of cars pass through die intersection? c. Briefly describe the trend in numbers of cars over the course of die day. d. Provide a hypothesis explaining the trend in numbers of cars over the course of the day. e. Provide a possible experiment that could test your hypothesis.arrow_forward
- Suppose that you are closing a cabin in the north woods for the winter and you do not want the water in the toilet tank to freeze. 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_forwardMake a drawing, based on the kinetic-molecular theory and the ideas about atoms and molecules presented in this chapter, of the arrangement of particles in each of the cases listed here. For each case, draw 10 particles of each substance. It is acceptable for your diagram to be two dimensional. Represent each atom as a circle, and distinguish each different kind of atom by shading. (a) a sample of solid iron (which consists of iron atoms) (b) a sample of liquid water (which consists of H2O molecules) (c) a sample of water vaporarrow_forwardA 15.5 g sample of sodium carbonate is added to a solution of acetic acid weighing 19.7 g. The two substances react, releasing carbon dioxide gas to the atmosphere. After reaction, the contents of the reaction vessel weigh 28.7 g. What is the mass of carbon dioxide given off during the reaction?arrow_forward
- 3.83 For the reaction of nitrogen, N2, and hydrogen, H2, to form ammonia, NH3, a student is attempting to draw a particulate diagram, as shown below. Did the student draw a correct representation of the reaction? If not, what was the error the student made?arrow_forwardA chemist prepares a solution of silver(I) nitrate AgNO3 by measuring out 6.4102 x 10^2 μmol of silver(I) nitrate into a 450.mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's silver(I) nitrate solution. Round your answer to 2 significant digits.arrow_forwardA sample of tap water contains 1.95 x 103 ppm CaCO3(aq). Assuming the density of tap water is 1.00g/mL, calculate the mass of CaCO3 in 2.00 L of water.arrow_forward
- While in Europe, if you drive 101 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 25.0 mi/gal ? Assume that 1euro=1.26dollars.arrow_forwardA chemist samples a river's water to measure the amount of fertilizer runoff from the area farms. In a 0.07750.0775 L sample, the chemist measures 327327 μg of nitrate. Express the concentration of nitrate in parts per million (ppm) and parts per billion (ppb). Assume the density of the river water sample is 1.00 g/mL. concentration: _____ ppmppm concentration: _____ppbarrow_forwardA chemist adds 70.0mL of a 2.40 x 10^−4 mol/L copper(II) fluoride (CuF2) solution to a reaction flask. Calculate the micromoles of copper(II) fluoride the chemist has added to the flask. Be sure your answer has the correct number of significant digits.arrow_forward
