Consider the sodium vapor lamps described in question 13. how much energy is emitted by 45.8 mg of sodium atoms emitting light at this wavelength? assume each sodium atom emits one photon.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

vapour or gas assuming atmospheriv pressure

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

cant without the picture! ?
