A brick laying machine spits out bricks horizontally. If each brick weights 2 kg each and the machine spits out the bricks with a speed of 4 m/s, how much net force is required to keep the object moving at this speed and in the same direction?

How have the greenhouse gasses increased from the year 2000 to 2018

How might this scientific phenomena be explained? a paper clip floats on water.

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
