Identify and label the bronsted lowry acid, its conjugate base, the bronsted-lowry base, and its conjugate acid in each of the following equations (a, b, ca, cb): a. hbr h2o --> h30 br-
b. NO-2 H2o --> HNO2 OH-

Explanation:

A bronsted lowry acid is any species that can donate a hydrogen proton (H+) to another molecule.

A bronsted lowry base is any species that can receive a hydrogen proton (H+) from another molecule.

a. hbr h2o --> h30+ br-

The Bronsted-Lowry acid is HBr

It's conjugate base is Br-

The Bronsted-Lowry base is H2O

It's conjugate acid is h30+

b. NO-2 H2o --> HNO2 OH-

The Bronsted-Lowry acid is H2O

It's conjugate base is OH-

The Bronsted-Lowry base is NO-2

It's conjugate acid is HNO2

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
