Using the br? nsted-lowry concept of acids and bases, identify the br? nsted-lowry acid and base in each of the following reactions:
h2po3? (aq)+h2o(l)? h3po3(aq)+oh? (aq)
(ch3)2nh(g)+bf3()2nhbf3(s)
drag the appropriate items to their respective bins.
h2po3- h2o bf3 (ch3)2nh
bronsted lowry acid bronsted lowry base neither

is Bronsted Lowry base.

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 baseA base is defined as a substance which accepts protons and forms conjugate acid.

is Bronsted Lowry base.It accepts protons and forms conjugate acid

is Bronsted Lowry acid.It donates protons and forms conjugate base

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

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
