It has an incredibly high pH, and anything above 7 on the pH scale is a base

Explanation:

Bases are those substance which releases hydroxide ions in aqueous solution when dissolved in water.

$BOH(aq)\rightarrow B^+(aq)+OH^-(aq)$

As we can see that in formula of aluminium hydroxide , there are 3 hydroxide ions attached to single aluminum ion. So, when we will dissolve the aluminum hydroxide in water it will give aluminum ions and hydroxide ions in its solution.

$Al(OH)_3(aq)\rightarrow Al^{3+}(aq)+3OH^-(aq)$

Marrrta [24]

Answer:

The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another. This law is taught in physical science and physics classes in middle schools and high schools, and is used in those classes as well as in chemistry classes. When playing pool, the cue ball is shot at a stationary 8 ball. The cue ball has energy. When the cue ball hits the 8 ball, the energy transfers from the cue ball to the 8 ball, sending the 8 ball into motion. The cue ball loses energy because the energy it had has been transferred to the 8 ball, so the cue ball slows down.

OverLord2011 [107]

Question: The question is incomplete. Below is the complete question and the answer;

While ethanol (CH3CH2OH is produced naturally by fermentation, e.g. in beer- and wine-making, industrially it is synthesized by reacting ethylene CH2CH2) with water vapor at elevated temperatures. A chemical engineer studying this reaction fills a 50.0 L tank at 22. °C with 24. mol of ethylene gas and 24. mol of water vapor. He then raises the temperature considerably, and when the mixture has come to equilibrium determines that it contains 15.4 mol of ethylene gas and 15.4 mol of water vapor The engineer then adds another 12. mol of water, and allows the mixture to come to equilibrium again. Calculate the moles of ethanol after equilibrium is reached the second time. Round your answer to 2 significant digits.

Answer:

Number of moles of ethanol = 11 mol
