How are reflecting telescopes different from refracting telescopes? *

Reflecting telescopes need light sources; refracting telescopes don't.
Reflecting telescopes magnify objects; refracting telescopes minimize them.
Reflecting telescopes magnify objects in outer space; refracting telescopes only magnify objects on Earth.
Reflecting telescopes use mirrors to collect light; refracting telescopes use lenses.

What is the most stable monatomic ion formed from nitrogen

Chromosome 17 is made of over million base pairs.

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
