Which species is the conjugate base of H2SO3

Chemistry

1 answer:

ryzh [129]2 years ago

4 0

Explanation:

As you know, the conjugate base of an acid is determined by looking at the compound that's left behind after the acid donates one of its acidic hydrogen atoms.

The compound to which the acid donates a proton acts as a base. The conjugate base of the acid will be the compound that reforms the acid by accepting a proton.

In this case, sulfurous acid has two protons to donate. However, the conjugate base of sulfurous acid will be the compound left behind after the first hydrogen ion is donated.

A community consists of all the organisms in an ecosystem that belong to the same species.

choli [55]

Answer:

False

Calculate hydrochloric acid (umol)in 200 ul of a 0.5173Msolution of acid?

strojnjashka [21]

Answer: The moles of hydrochloric acid is $1.0346\times 10^{-4}\mu mol$

Explanation:

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}$

Or,

$\text{Molarity of the solution}=\frac{\text{Micro moles of solute}\times 10^6}{\text{Volume of solution (in }\mu L)}}$

We are given:

Molarity of solution = 0.5173 M

Volume of solution = $200\mu L$

Putting values in above equation, we get:

$0.5173M=\frac{\text{Micro moles of HCl}\times 10^6}{200\mu L}\\\\\text{Micro moles of HCl}=1.0346\times 10^{-4}\mu mol$

Hence, the moles of hydrochloric acid is $1.0346\times 10^{-4}\mu mol$

Identify each enthalpy change by name and classify each change as exothermic or endothermic.

Len [333]

We classify them as follows:

1. 1 mol NaCl (s) à 1 mol NaCl(l)
C Molar heat of fusion; endothermic

2. C4H10 O(l) à C4H10O (g)
B Molar heat of vaporization; endothermic

3. H2O(g) à H2O (l)
D Molar heat of condensation; exothermic

4. 1 mol NaCl(s) + 3.88 kJ/molà 1 mol NaCl(aq)
A Molar heat of solution; endothermic
