Answer:
Explanation:
Iron granules are separated from dust particles by using a magnet. The 'magnetic field' of the magnet will influence the iron granules that gets magnetized and attracted to the magnet.
Answer is: Velocity and spacing of particles is reduced and Volume of substance decreases relative to temperature decrease.
Charles' Law (The Temperature-Volume Law) - the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature:
V₁/T₁ = V₂/T₂.
When temperature goes down, the volume also goes down.
Velocity is equivalent to a specification of its speed and direction of motion, it is a physical vector quantity. Less enegry (lower temperature), lower the velocity.
The difference between phyisical and chemical change is the phyisical change is by nature and chemical change is by substance
The answer is C, Extinction.
If there was no diversity then a single sickness could wipe out a whole population, but if the population was more varied theres a higher chance someone is more resistant to the sickness and could carry on the species life
Answer:
The value of the of the acid is :
Explanation:
The pH of the weak acid solution = 3.879
Concentration of hydrogen ions =
Concentration of hypochlorous acid solution = [HClO]= 0.426 M
Initially:
0.426 M 0 0
At equilibrium
(0.426-0.0001321)M 0.0001321 M 0.0001321 M
The expression of will be given as;
The value of the of the acid is :
