Cao(s) + h2o(l) = ca(oh)2(s) what mass of slaked lime can be produced from a mixture of 28.4 g of cao and 13.3g of h20

Aradio signal from a gps satellite take only about 0.067 seconds to reach a gps reciever. if the speed of light is about 300,000km/s, then approximately how far away is the reciever from from the satellite?

Classify this reaction: 2al+n2-> aln.

Word equation for k(s)+h2o(l) yield koh(aq) + h2(g)
