Answer:
i think its 3
Explanation:
because cloud are made from water vapor and clouds also got preciptation if im wrong sorry
Reaction
2AgNO₃ + Cu ⇒ Cu(NO₃)₂ + 2Ag
mol silver (Ag): 95.3 : 108 g/mol = 0.882
mol copper nitrate (Cu(NO₃)₂): 82.9 : 187.5 g/mol = 0.441
mol Ag = 2 x mol Cu(NO₃)₂, so 0.441 being the mole basis of the reactants
mol Cu = 0.441
mass Cu = 0.441 x 63.5 g/mol = 28 g
mol AgNO₃ = 0.882
mass AgNO₃ = 0.882 x 170 g/mol = 149.94 g
Answer:
Hydrocarbon being non polar are soluble only in non polar solvent.
Explanation:
Hydrocarbon molecules either have very little polarity or they do not have polarity at all, this is because of absence of electro-negative atoms in their molecular structure. Due to this their solubility is also affected. The solubility of a compound depends on its polarity as it can dissolve in a polar solvent only when it is polar or else they are soluble in non-polar solvent
Aloha~! My name is Zalgo and I am here to help you out today. Those sort of conditions could be fore-boding/foreshadowing/warning that there will soon be a storm or that it will rain quite a lot. In the case of it being a storm, you should be a small room where there are no windows and nothing that is small that will fly towards you that could kill you.
I hope that this helps! :D

Base on the question all about the human eye were an optic nerve of it needs an energy of 2.10x10^-17J that could trigger a series of impulses that eventually reach to the brain. So the possible photons of blue light needed for for this energy is 52 photons
