Connect and Apply scientific knowledge to explain the following situations: a. Link the concepts of mole, molar mass, number of atoms, Avogadro’s
number and mass using a flowchart or mind map.

b. Rearrange the two equations to make each variable the focus (you will end up with three variations for each equation).

c. Record the equations for number of moles and number of particles (and
each equation triangle) - Annotate each symbol with what it means and definition and the units.

d. Explain mole concept using any real life example

b.Rearrange the two equations to make each variable the focus (you will end up with three variations for each equation).

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

i just learnt this recently but i need to look through my notes again
