The balanced chemical equation for the reaction of copper (cu) and silver nitrate (agno3) is shown below. cu + 2agno3 mc001-1.jpg 2ag + cu(no3)2 how many moles of copper must react to form 3.50 mol of ag?

1.75 moles of copper must react to form 3.50 mol of Ag.

Explanation:

According to reaction 2 moles of silver are obtained from 1 mole of copper.

Then 3.50 mole of Silver will be obtained from:

1.75 moles of copper must react to form 3.50 mol of Ag.

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

it should be all of them because it asks if you included all of those in your answer
