Assuming that there is missing information in this question I’m just going to go ahead and say that it’s lower.
HNO3 (nitric acid) is a very strong acid which should be found on the lower end of the pH scale. While water, on the other hand, is neutral and found at a pH of 7.
So if you add one drop of a strong acid into a neutral solution of 100ml let’s say, one can assume that the pH of that solution is now very low and probably found between 1-3 on a pH scale.
Reminder:
-Acids are found between 1-6 on the pH scale. The lower the number the stronger the acid
-Bases are found between 8-14 on the pH scale. The higher the number the stronger the base
2NH3(g) = N2(g) + 3H2(g)
Before decomposed :
P NH3 = 2.7 atm
After decomposed :
P N2 = 0.54 atm
P H2 = P N2 / 3 = 0.54 / 3 = 0.18 atm
P NH3 = 2.7 - 2(0.18) = 2.34 atm
Pressure equilibrium constant :
Kp = (P N2)(P H2)³ / (P NH3)²
Kp = (0.54)(0.18)³ / (2.34)²
Kp = 5.75 × 10^(-4)
Answer:
why can you never trust a atom
Explanation:
they make everything up
Answer:
True
Explanation:
The complete question is:
<u><em>"A reaction contains two reactants, A and B. If A is doubled, there will be a greater number of effective collisions between reactants. TRUE FALSE"</em></u>
Collision Theory indicates that chemical reactions take place because molecules, atoms or ions collide with each other.
Furthermore, the molecules must collide effectively, that is, not all reagent collisions lead to product formation. Effective shock means that the reagent molecules have enough kinetic energy at the time of the shock for their bonds to break and product bonds to form. In addition, the molecules of the reagents must be properly oriented for the reaction to take place.
As the concentration increases, the number of shocks increases. In other words, by increasing the concentration of the reactants, the probability of collision between their molecules increases, and therefore the number of effective collisions.So the statement is true-
