Chemist lectures about the following definition for acids and bases.

The acid-base behavior is analyzed in terms of how electrons are transferred between compounds rather than in terms of how hydrogen ions are transferred.

What is the chemist defining?
the Arrhenius concept of acids and bases
the classical concept of acids and bases
the Lewis concept of acids and bases
the Bronsted-Lowry concept of acids and bases

The correct answer is "the Lewis concept of acids and bases".

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
