Which of the following statements about the reaction of one mole of methane at STP is NOT correct? CH4(g) + 2O2(g) CO2(g)+ 2H2O(g) O In a 1:1 ratio of CH4(g) and O2(e), methane would be the limiting reagent. O Guy Lussac's Law of combining volumes suggests a whole number ratio for products and reactants of 1 22.4 liters of methane would react stoichiometrically with 44.8 liters of oxygen If CH4(e) and are O2(g) initially present in a 1:2 ratio, there will be no change in the overall volume of the system after reaction.​

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

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
