Power has no effect on regardless of whether the photoelectric impact happens. The deciding property is recurrence and since recurrence and wavelength are conversely corresponding, wavelength matters also. On the off chance that a recurrence of light can't make the photoelectric impact happen, regardless of what the power is, the light can't get it going.
Answer:
1350 g
Explanation: just add a 0
I believe it would be the sum of protons & neutrons which equals 9 amu....
5/8=0.625 4/5=.8
5/8 because 5/8=0.625 and because its 2x you multiply 0.625 by 2=1.25 then you do 1.25+5=6.25 4/5=.8 6.25 times .8=5 5-4=1
X=5/8 or 0.625
Answer:
hydrochloric acid
Explanation:
The hydrochloric acid in this reaction is the limiting reactant. A limiting reactant is the reactant that is used up in a chemical reaction. It determines the extent of the reaction.
Since the solution indicates a basic one after the end of the reaction, this suggests that more of the sodium hydroxide is still left unreacted with.
The reactant in excess supply here is the sodium hydroxide and the bulk of it is till left in solution.
