A radioactive substance decays according to A = Age-0.0049, where Ao is the initial amount and it is the time in years. If Ao = 550 grams, find the time for the radioactive substance to decay to 193 grams. Round your answer to two decimal places, if necessary.

Consider the accompanying diagram. Ball A is allowed to fall and strike ball B. Assume that all of ball As energy is transferred to ball B at point I, and that there is no loss of energy to other sources. What is the kinetic energy and the potential energy of ball B at point II? The potential energy is given by PE = mgz, where m is the mass in kilograms, g is the gravitational constant (9.81 m/s2), and z is the distance in meters.

The amount of radioactive substance present, in grams, at time t in months is given by the formula y=7000(3)-0.3t. Find the number of grams present in 4 years. If necessary , round to the third decimal places.
Carbon 14 dating The technique of carbon 14 (4C) dating is used to determine the age of archaeological and geologi- cal specimens. The formula T = -8310 In x is sometimes used to predict the age T (in years) of a bone fossil, where x is the percentage (expressed as a decimal) of 14C still pres- ent in the fossil. (a) Estimate the age of a bone fossil that contains 4% of the 14C found in an equal amount of carbon in present- day bone. (b) Approximate the percentage of "C present in a fossil that is 10,000 years old.
. Suppose 1.00 mole of pennies (each penny is 0.0598 inch thick) is stacked one atop another to make a very tall pile. Starting from the bottom of the pile in a spacecraft traveling at the speed of light (3.00 x 108 m/s), how many years will it take to reach the top of the pile of pennies? Show all your work.
When Kay added 30g of Hydrochloric acid (HCI) to 65g of Zn, bubbles appeared and a white precipitate, zinc chloride (ZnCl2) was produced. She found that the mass of the zinc chloride was 93g. Since the law of conservation of matter stated that matter can’t be created or destroyed, she was puzzled about the difference in mass. What is the best explanation for the missing 2g?

Q29 Santa Monica Big Blue Bus operates a fleet of CNG buses, which run on compressed natural gas (CNG), natural gas that has been compressed into a much smaller volume in the fuel tank. A newly designed CNG vehicle carries about several thousand cubic feet of compressed natural gas which contain 72 kg (kilograms) of carbon. If all of the natural gas is burned, how many kilograms of carbon dioxide will be emitted into the atmosphere? Assume no residue remains and the carbon dioxide is the only product in the combustion. If you are presenting this question, please explain the following: The steps in the calculation process O Please write out the steps involved in the conversion process including the units O Please explain how to operate on the units Please explain how to manipulate the powers of ten by hand (e.g. product rule and the quotient rule) How to apply the appropriate rule to the calculation: O addition-subtraction rule ("the decimal places rule"), OR multiplication-division…
The mass of magnesium used in this experiment is critical to determining the moles of hydrogen gas generated. The analytical balances used in Chemistry 1A labs are very sensitive to point that touching materials with your fingers before measuring them can affect the measurements. The balances are sensitive enough to detect dirt and oils from your fingers transferred to the magnesium. Would your experimental value of R increase or decrease if the mass of magnesium measured was artificially high due the touching it with your hands? Increase Decrease
