10) The international space station (ISS) orbits the Earth from
an altitude of 408 km.
a) Calculate the strength of Earth’s gravity on the ISS at that
altitude. (Hint: How far is the ISS from the center of mass of the
Earth?)
b) Earth’s gravity is what keeps the ISS in its orbit (which we
will assume is circular). At what speed does the ISS orbit the
Earth?

How many grams of HCl, are needed to produce 125 ml of carbon dioxide gas at STP in the following reaction? CaCO3(s) + 2 HCl(aq) - -> CaCl(aq) + CO2(g) + H20(1) In a reaction similar to this laboratory experiment, 0.625 g of aluminum metal was completely consumed and the H, gas collected over water at 55.0°C and atmospheric pressure of 759 mm Hg. What was the volume of H, gas produced? (Be sure to correct H2...

10) The international space station (ISS) orbits the Earth from
an altitude of 408 km.
a) Calculate the strength of Earth’s gravity on the ISS at that
altitude. (Hint: How far is the ISS from the center of mass of the
Earth?)
b) Earth’s gravity is what keeps the ISS in its orbit (which we
will assume is circular). At what speed does the ISS orbit the
Earth?
