The semi will have the hardest time changing direction because of its mass. The more mass there is, the more effort it takes to accelerate and decelerate as well as change direction.
An increase in H+ concentration will decrease OH- concentration is the
reason why it's impossible.
<h3>What is an Acidic and Basic compound?</h3>
An acidic compound has the presence of H+ ions in them while basic
compounds have the presence of OH- ions.
In a solution , as the number of Hydrogen ions increases, it leds to a
corresponding decrease in the Hydroxide ions which is the reason why
they can't coexist at the same time.

3/8 NA = 3/8 x 6.023 x 10^23 molecules of h2o
so, we can easily conclude that 1mole of CH4 gives 2mole of H2o
