Radio waves travel at the speed =3.00 108 m/s(speed of light,). if Saturn is 7.9 108 km from Earth then Determine how many minutes does it take for a radio message to reach Earth from Saturn?
A container consists of CO2 gas at a temperature of 15 C and at a pressure of .990 atmospheres. The volume of the container is 500 mL. How many grams of CO2 would be in the container?
Water autoionizes to produce hydronium ion and hydroxide ion. The product of the concentrations of these ions equals the water autoionization constant, Kw. This ionization constant depends on temperature, the enthalpy change, and the entropy chang..
Calculate the percent error in the experiment using the experimental and theoretical values of the mass percent of oxygen.
calculate the difference in mass that is hold by a 500.0mL flask at a temperature of 0.0°C from that at temperature of 20.0 °C? (you can assume the volume of the sample at 0.0 °C temperature =volume of the sample at 20.0°C)
