How many mL are 2.3 mol of CO2 at STP?
kupik [55]

Answer:

0.052mL

Explanation:

1mole of a gas occupy 22.4L.

Therefore, 1 mole of CO2 will also occupy 22.4L.

If 1mole of CO2 occupies 22.4L,

Then 2.3moles of CO2 will occupy = 2.3 x 22.4 = 51.52L

coverting this volume to mL, we simply divide by 1000 as shown below:

51.52/1000 = 0.05152mL = 0.052mL

Using the Br?nsted-Lowry concept of acids and bases, identify the Br?nsted-Lowry acid and base in each of the following reaction
antiseptic1488 [7]

Answer:

H_2PO_3^- is Bronsted Lowry base.

H_2O is Bronsted Lowry acid.

Explanation:

According to the Bronsted Lowry conjugate acid-base theory:

  • An acid is defined as a substance which donates protons and form conjugate base
  • A base is defined as a substance which accepts protons and forms conjugate acid.

H_2PO_3^-(aq)+H2O(l)\rightarrow H_3PO_3(aq)+OH^-(aq)

H_2PO_3^- is Bronsted Lowry base.It accepts protons and forms conjugate acid H_3PO_3

H_2O is Bronsted Lowry acid.It donates protons and forms conjugate base OH^-

(CH_3)_2NH(g)+BF_3(g)\rightarrow (CH_3)_2NHBF_3(s)

There in no exchange of proton in an above reaction.Neither of the reactants and products are Bronsted Lowry acid or Bronsted Lowry base
