Answer:
The pressure inside the container will increase by increasing the amount of gas.
Explanation:
It can be better understand through ideal gas equation,
PV = nRT
By keeping the volume and temperature constant, the pressure of gas in container will increase when amount of gas goes to increase.
PV = nRT
P = nRT / V
P = (1+ 14) RT/V
P = 15
The pressure will increase 15 fold.
In neutralization reactions, a base and an acid react to form an ionic salt and water. There is a rule that when a strong base and a strong acid react, the pH of their salt is always neutral which is at pH 7. However, this is only true if equal amounts of acid and base are consumed and that there is no excess. Otherwise, the excess acidity or basicity will adjust the total pH.
Strong acids are the following: HCl, HBr, HI, HClO4, HClO3, HNO3 and H2SO4. Strong bases are KOH, LiOH, NaOH, Ca(OH)2, Sr(OH)2 and Ba(OH)2. Therefore, we can already establish that both of the reactants are strong. The complete reaction is
HBr + KOH ⇒ KBr + H₂O
So, 1 mole of HBr would require 1 mol of KOH, and vice versa. Let'scompute the amount of the initial reactants:
mol HBr: (0.25 mol/L)*(0.92 L) = 0.23 mol HBr
mol KOH: (0.5 mol/L)*(0.46 L) = 0.23 mol KOH
There are equal amounts of acid and base. Thus, pH of the KBr solution is neutral at pH 7.
Answer:
Laws of Nature are to be distinguished both from Scientific Laws and from Natural Laws. On the other account, the Necessitarian Theory, Laws of Nature are the principles which govern the natural phenomena of the world. That is, the natural world “obeys” the Laws of Nature.
According to Le Chatelier's Principle, to increase the rate of the forward reaction we add more of the reactants to encourage more collisions and production of more products. If it is endothermic, more heat should be added. If it is endothermic, more heat should be released from the system.
It will have 35 ''electrons'' . Basically the number of protons in the nucleus of an atom is always equal to the number of electrons but its just that protons are positively charged and electrons are negatively charged. <span />
