an electromagnet wave can go through objects
Answer:
The warmer, lighter air rises, bringing cooler, heavier air to low altitudes.
Air at higher altitudes doesn't have as much air weighing down on it from above.
Explanation:
In short - air pressure is the result of the cumulative force that air molecules act on objects below them due to Earth's gravity. The higher the altitude, the less air molecules there are to act a force below them, and therefore, there's less air pressure at higher altitudes.
Answer:
π = MRT
= × RT
= ×RT
MM = mxRxT / πxL
MM = 8.00g ×0.0821×298/ 2.86×0.200L
= 342.2 g/mol
Explanation:
the molecular weight of the sugar can be determined by using the osmotic pressure formula.the formula has to be worked on in order to get the molar mass of the sugar.the name of the sugar is called sucrose.
According to VSEPR theory, what causes water molecules to have a bent shape?
Answer: Out of all the options presented above the one that best represents what causes water molecules to have a bent shape according to VSEPR theory is answer choice B) repulsive forces between specific lone pairs of electrons. the bond angle in a water molecule is bent.
I hope it helps, Regards.
