PLEASE IM IN A TEST A piece of lithium was weighed on a balance reading to 3 decimal places. The mass recorded was 0.120 g. It was then added to 50 cm 3of water in a beaker (in excess). Calculate the maximum volume of hydrogen, in cm 3, which would be formed at a temperature of 20°C and a pressure of 1.0 × 10 5Pa.

The diagram shows the structures of horse and cat forelimbs. what does the diagram suggest about the evolutionary relationship between these two mammals? a. they have homologous structures, indicating a common ancestor. b. they have analogous structures, indicating a common ancestor. c. they have homologous structures, indicating that they do not have a common ancestor. d. they have analogous structures, indicating that they do not have a common ancestor.

3. how much energy in joules is required to evaporate .0005 kg of liquid ammonia to vapor at the same temperature? 4. how much energy ( in megajoules ) is given up by .75 kg of water at 0c when it freezes to form ice at 0c? 5. explain how heat works between and at critical temperatures?

If an area has high air pressure and low humidity, what type of weather will it most likely have? plz !
