Answer:
A Brønsted-Lowry acid is a substance which donates protons to other substances. (option c.)
Explanation:
For Brønsted-Lowry acids, are the ones that donates protons and bases, the ones that accepts H⁺ from others compounds.
In this reaction:
NH₃ + HCl → NH₄Cl
The hydrocloridic acid donates the proton to ammonia to make ammonium chloride. So the HCl, is a Brønsted-Lowry acid while the ammonia is a base.
There are cases, like water that behaves as acid and base.
These compounds are called amphoteric because it can donate H⁺ or OH⁻ at the same time.
H₂O ⇄ H⁺ + OH⁻
Answer:
P (H₂) = 741 torr
Explanation:
Let's begin by listing out the given parameters:
Temperature (water) = 298 K, volume = 45.6 mL,
atmospheric pressure, P (total) = 765 torr, vapor pressure of water, P (H₂O) = 24 torr
To get the pressure of inside the tube, P (H₂), we apply Dalton's Law of Partial Pressure and we have:
P (total) = P (H₂) + P (H₂O)
P (total) = 765 torr, P (H₂O) = 24 torr
P (H₂) = P (total) - P (H₂O) = 765 - 24
P (H₂) = 741 torr
It therefore becomes clear that the pressure of H₂(g) is 741 torr
Answer:
Explanation:
According to the law of mass action:-
The rate of the reaction is directly proportional to the active concentration of the reactant which each are raised to the experimentally determined coefficients which are known as orders. The rate is determined by the slowest step in the reaction mechanics.
Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.
The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.
From the reaction given that:-
The expression for the rate is:-
![r=k[P]^2](https://tex.z-dn.net/?f=r%3Dk%5BP%5D%5E2)
Given that;- k= 
/Ms
[P] = 
M
Thus,
Angiosperms can produce flowers and fruits to aid in seed dispersal.
Answer: I believe that Humans will evolve with the following features: Taller legs and bodies, better vision, possibly more teeth, and maybe an extra finger or two
Explanation:
I believe this because evolution is meant to help organisms survive
