Analyzing the Relationship between Mass and KE
Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a
100 kg ball traveling at 5 m/s.
A 1,000 kg ball traveling at 5 m/s would have
v kinetic energy
A 10 kg ball traveling at 5 m/s would have
kinetic energy
A 100 kg person falling at 5 m/s would have
v kinetic energy

The alkali metals (group 1) consist of lithium (3), sodium (11), potassium (19), rubidium (37), cesium (55), and francium (87). they are soft, metallic solids with low densities and low melting points. based on the data shown in figure 1, how many valence electrons do alkali metals share?

Air can be considered a mixture. which statement does not explain why?

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
