Answer:
The correct answer is: Yellow
Explanation:
<u>The given reaction at equilibrium</u>: A⁻(aq) + H₂O(ℓ) ⇋ HA(aq) + OH⁻(aq)
Given: Solution color at high product (HA) concentration = yellow
Solution color at low product (HA) concentration = red
Initial color of solution = orange
According to the Le Châtelier's principle, <u>addition of reactan</u>t to the reaction at equilibrium, shifts the equilibrium towards the right side of the reaction or towards the forward direction. <u>Therefore, favoring the product formation.</u>
So, if the <u>reactant A⁻(aq) is added to the reaction mixture</u>, more product (HA) is produced. <u>Therefore, the concentration of the product HA increases. </u>
Since the solution is <u>yellow in color at high product (HA) concentration</u>.<u> </u>
<u>Therefore, when the concentration of the product HA increases upon the addition of reactant A⁻(aq), the color of the solution changes from orange to yellow.</u>
Answer:
By looking at the periodic table, you will see that Fluorine has 9 protons. Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well. Meanwhile, it's mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.

The ideal gas law is presented
by the equation PV = nRT. n, the number of moles, is equal to mass over molar
mass. And density is M/V.
PV = nRT
PV = (M/molar mass)RT
P/RT = (1/molar mass)(M/V)
M/V = D = (molar mass)(P/RT)
Molar mass of CO2 = 44 g/mol
D = (molar mass)(P/RT)
D = (44 g/mol)(1 atm)/(0.08206
L-atm/mol-K)(273K)
D = 1.964 g/L
