Answer:
The primary role of the carbonic-acid-bicarbonate buffer system is to neutralize the hydronium ions forming carbonic acid and water when any acidic substance enter the bloodstream.
Explanation:
hope it helps.
Answer:
The answer is in the explanation.
Explanation:
The dissociation of a weak acid consist in the following equilibrium:
HX ⇄ H⁺ + X⁻
Where Ka is defined as:
Ka = [H⁺] [X⁻] / [HX]
A strong acid (HY) dissociates completely in water, thus:
HY → H⁺ + Y⁻
As the strong acid produces H⁺, in the equilibrium, the reaction shifts to the left -The undissociated form-, reducing the production of H⁺, allowing ignore the dissociation of the weak acid when calculating the pH.
Answer:
The mass of formed sodium sulphate solution is 14.2 g.
Explanation:
From the given,
Mass of copper sulphate = 15.9 g
Mass of sodium sulphide = 7.8 g
Total mass of reactant = Mass of copper sulphate + Mass of sodium sulphide
= 15.9 + 7.8g = 23.7g
Mass of copper sulphide formed = 9.5 g
Mass of sodium sulphate = Total mass - Mass of copper sulphide
= 23.7 g - 9.5 g = 14.2 g
Therefore, The mass of formed sodium sulphate solution is 14.2 g.
Answer:
Slab pull is the theory of plate movement which relies on the weight of the subducting crust.
Explanation:
Plate movement are the measure of motion of tectonic plates. As it is known that our earth crust is composed of different sizes of tectonic plates. So these plates can move depending upon the pressure exerting on it. So slab pull is one of the theories existing with plate movement. In this case, the movement of the plates occur due to the weight of the subducting crust. The subducting crust is the boundary between tectonic plates. So depending upon their weights, the slab pull theory works.
Answer:
Remove the outer layer of sodium oxide that formed to allow for a quicker reaction
Explanation:
The purpose of not using a paper towel to dab off your metal is :
Remove the outer layer of sodium oxide that formed to allow for a quicker reaction.
The process of Dabbing is nothing but applying doses of a cannabis concentrate that gets vaporized on a surface which is heated up.
The daboff the metal by normal paper towel cannot remove the outer oxide layer.
