Because a single computer can store more data than many journals put together. Computers have a large memory. Not only can scientific data be stored but it can be retrieved easily.
When salt is added to ice , it comes into contact with the thin layer of water on the surface of the melting ice. ... This salt water has a lower freezing point, so the temperature of the ice bath can get even colder, thus freezing the ice cream more quickly.
Answer:
Explanation:
phenolphthalein indicator is an acid - alkaline organic dye that changes color over a particular pH range depending on the medium. As such , asides phenolphthalein, methyl orange, Alzarian yellow are other indicators that are used during avid - base titration experiment.
In this case, phenolphthalein in an acidic medium is colorless while in basic medium is pink. Also phenolphthalein been a weak acid reacting with the hydroxide thereby reducing the concentration, this will have an effect on the equilibrium position by favoring the forward reaction i.e product formation. hence more products will be formed.
In the case of ammonium chloride, the addition of more ammonium ions results in an increase in the concentration of the products and as such, if more ammonium ions are removed, the equilibrium position will shift to favor the backward reaction i.e reactant formation.
Answer:
It has four main components: plasma, red blood cells, white blood cells, and platelets.
Answer:
The NaCl concentration will be 0.03 M.
Explanation:
Given data:
Initial volume = V₁ = 56.98 mL (56.98/1000 = 0.05698 L)
Initial concentration = M₁= 0.5894 M
Final volume = V₂= 1.20 L
Final concentration = M₂= ?
Solution:
By diluting the solution volume of solution will increase while number of moles of solute remain the same.
Formula:
Initial concentration × Initial volume = Final concentration × Final volume
M₁V₁ = M₂V₂
M₂ = M₁V₁ / V₂
M₂ = 0.5894 M × 0.05698 L / 1.20 L
M₂ = 0.0336 M /1.20
M₂ = 0.03 M
