When a substance is soluble in water, the smallest pieces of the substance spread out in the water as individual atoms or molecules.

How does being dissolved in water affect two substances that are chemically reacting with one another?
A.
It stops the chemical reaction from occurring.
B.
It helps the chemical reaction occur more easily.
C.
It makes the chemical reaction occur slower.
D.
It causes the substances to react with the water.

how to make a simple air condition

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
