No, a precipitate will not form when barium nitrate, Ba(NO3)2, reacts with potassium hydroxide, KOH, in aqueous solution because both products are soluble in water.
Answer:
The correct answer is - both act only between non-atomic particles.
Explanation:
The decreasing order of their relative strength is - the strong force, electromagnetism, weak force, gravity.
so, A would be here = gravity
B would be = weak force
C would be = strong force
The weak and strong forces both are fundamental forces that act on sub-atomic particles only such as quarks.
Answer:
The "simple" hurdle that must be overcome to turn seawater into freshwater is to remove the dissolved salt in seawater. That may seem as easy as just boiling some seawater in a pan, capturing the steam and condensing it back into water (distillation).
<span>Answer:
I'm assuming the question is asking when it "jumps" from level 2 to level 1. In which case: 1/λ = Rh(1/nf^2 - 1/nfi^2) = 1.10x10^7 (1/1^2 - 1/2^2) = 1.10x10^7 ( 1 - 0.25) = 1.10 x10^7 (0.75) λ = 1.21 x 10^-7 m The wavelength produced will be about 1.21 x 10^ -7 m, or 121 nm.</span>
