Ethene will not typically react with hydrogen gas through simple bimolecular collisions. Using the picture, explain how this rea

ction becomes possible.
A: A metal surface is catalyzing the reaction by speeding up the kinetic energy of hydrogen gas and, as a result, breaking its bonds so that it can react with ethene.

B: A metal surface is acting as a catalyst and lowers the activation energy of bond breaking of hydrogen gas.

C: Ethene is stabilized by a metal surface and hydrogen gas catalyzes the metal surface so that it can react with ethene.

D: Ethene is catalyzed by a metal surface and, therefore, raises the activation energy of hydrogen gas breaking apart.

The statements that describe how the pond turned into the bog is as follows: Large water plants grew in shallow water around the edge of the pond.

<h3>What is a pond?</h3>

Pond is an inland body of standing water, either natural or man-made, that is smaller than a lake.

A bog is an area of decayed vegetation (particularly sphagnum moss) which forms a wet spongy ground too soft for walking.

This means that a pond can become a bog when existing plants in the pond decays until the land becomes soft.

Therefore, the statements that describe how the pond turned into the bog is as follows: Large water plants grew in shallow water around the edge of the pond.

Application of boyle's law a 12-liter tank contains helium gas pressurized to 160 atm. part b what size tank would be needed to
son4ous [18]
<span>According to Mendeleyev-Klapeyron’s equation pV = nRT, where p = 160 atm V = 12 R -constant 0.0821 & T = 298 in Kelvin Using given data, we can determine the amount of Helium gas: n = pV/RT = (160â™12)/(0,0821â™298) = 78,48 (mol) For atmospheric pressure (1 atm) and the same amount we can calculate the volume of tank, using previous equation: V = nRT/p = (78,48â™0,0821â™298)/1 = 1920 (liters) V = 1920 liters Thus Answer is 1920 liters</span>
