Answer: 2800 g
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 
of particles.
Given mass = 5 kg = 5000 g
1 mole of 
produces = 1 mole of 
50 moles of produces =
of
Mass of 
2800 g of is produced from 5.0 kg of limestone.

Answer:
Option A (They happen as the Sun hits its maximum and minimum level throughout the sky) is the correct option.
Explanation:
- Solstice seems to be the moment whereas at noon this same sun achieved its maximum as well as minimum position, actually results throughout the year's shortest as well as biggest days.
- We currently believe that perhaps the solstice seems to be an apocalyptic event, exacerbated either by the tilt of the globe’s axis and therefore its direction of movement in an elliptical orbit. Globe's rotation not everyone's travel time from either the sun was what was causing winter or even just summer.
Some other options given should not be in accordance with the given context. So, the correct approach would've been option A.
A highly corrosive acid should have a Ph balance between 0-6
This problem can be solved by Dalton's law of partial pressures which states that <em>in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases</em>.
Ptotal = P₁ + P₂ + P₃ + ..... + Pn
Herein, Ptotal = P(Ne) + P(Ar) + P(He)
Ptotal = 1.25 atm, P(Ne) = 0.68 atm and P(Ar) = 0.35
So, P(He) = Ptotal - P(Ne) - P(Ar) = 1.25 - 0.68 - 0.35 = 0.22 atm
