We anticipate that the resulting aqueous solution will be basic.

<h3>What is the definition of a weak acid?</h3>

Weak acids are those that do not dissociate completely in solution. A weak acid is defined as any acid that is not a strong acid. A weak acid's strength is determined by how much it dissociates; the more it dissociates, the stronger the acid.

<h3>What exactly is a conjugate base?</h3>

A conjugate base is the base member, X-, of two compounds that transform into one another by gaining or losing a proton. In a chemical reaction, the conjugate base has the ability to gain or absorb a proton.

<h3>According to the given information:</h3>

Calcium propionate [Ca(CH₃CH₂COO)₂

We know that Calcium propionate dissolves completely in water.

So,

Ca(CH_3CH_2+COO)_2→Ca^2^+ +2CH_{3}CH_2COO−

Water can protonate the propionate anion. When everything is balanced,

CH_3CH_2\\COO−+H2O⇌CH_3CH_2COOH+OH−

We anticipate that the resulting aqueous solution will be basic.

What is the correct order of these items from smallest to largest radius? Group of answer choices
Ivan

I'm assuming you're talking about atomic radius. It'd be the 2nd.

Fluoride has the smallest (group 17)

Oxygen has the 2nd smallest (group 16)

Sodium has the largest (group 1)

Sorry it took so long, didn't know it was multiple choice :)

Lakes that have been acidified by acid rain can be neutralized by limiting the addition of limestone how much limestone is requi
svet-max [94.6K]
From the given pH, we calculate the concentration of H+:
     [H+] = 10^-pH = 10^-5.5
We then use the volume to solve for the number of moles of H+:
     moles H+ = 10^-5.5M * 4.3x10^9 L =  13598 moles
From the balanced equation of the neutralization of hydrogen ion by limestone written as
     CaCO3(s) + 2H+(aq)  → Ca2+(aq) + H2CO3(aq)
we use the mole ratio of limestone CaCO3 and H+ from their coefficients, which is 1 mole of CaCO3 is to react with 2 moles of H+, to compute for the mass of the limestone:
     mass CaCO3 = 13598mol H+(1mol CaCO3/2mol H+)
                               (100.0869g CaCO3/1mol CaCO3)(1kg/1000g) 
                            = 680 kg
