The temperature will be 1200K if the volume remained constant
calculation
This is calculated using gay lussac law formula, that is P1/ T1=P2/T2 since the volume is constant
P1 = 100 Kpa
T1= 300 K
P2= 400 Kpa
T2=?
by making T2 the subject of the formula T2 =( P2 xT1)/P1
T2 is therefore = (400 KPa x 300 K) / 100 Kpa = 1200 K
Answer:
Nitric acid is a strong acid meaning it completely dissociates in water. Therefore, you can say that the concentration of H+ ions in solution is the same as the concentration of the acid (molar concentration). So once you have that, you can use the pH formula to find the pH of the acid.
pH = -log[H+]
So if you have .15 M HNO3 the pH is 0.82.
But, if you have a different concentration, the pH will change.

See below
Explanation:
Use Ideal Gas Law
PV = n RT using R = .082057366 l-atm/k-mol
T must be in Kelvin
solve for 'n'
.92 * 1.6 = n * .082057366 * 287
n = .0625 moles
then the mole weight: .0625 * x = .314
x = mole weight = 5.025 gm
"Systems with either very <u>low pressures or high temperatures</u> enable real gases to be estimated as “ideal.” "
Answer:
The correct answer is option B.
Explanation:
When we increase number of molecules of reactant frequency of the molecular collision increases due to which effective collision between reactant molecules to form a product also increases, With this overall rate of the reaction increases.
Where as:
When we increase the temperature of the reactant molecules increase in average kinetic energy of the molecules is observed.
When we increase the activation energy of the reaction rate of the reaction slows down,
Answer:
A practical pursuit of alchemy was the development of metallurgy practices.
Explanation:
As alchemists always tried to turn various metals into other things, metalworking techniques were developed even though their experiments were often unsuccessful.
