<span>According to Le Chatelier's Principle, the position of
equilibrium moves to counteract the change, the position of equilibrium
will move so that the concentration of
products of chemical reaction increase, if:</span>
<span>1) increase temperature, because this endothermic reaction.</span>
<span>2) increase concentration of reactant.</span>
<span>3) decrease pressure of the system, so reaction moves to direction where is more molecules.</span>

Answer:
323.99 mg
Explanation:
We need to find the mass of the aspirin tablet that contains 5.0 grains of aspirin.
1 pound = 7000 grains
We know that, 1 pound = 453.592 grams
Also, 1 pound = 453592 mg
Hence, 4 grains of aspirin contains 323.99 mg.
1×10^-4 = 0,0001M
pH = -log[H+]
pH = -log0,0001
pH = 4
<span>E = hxf, où h = constante de Planck = 6,626 x 10 ^ -34Js
E = 6,626 x 10 ^ -34 x 8.11 x 10 ^ 14 = 5.373 10^ -19 J </span><span>
