Answer:
Explanation:
a )
From the graph given , energy of reactant = 0
b )
energy of product = -15 kJ
c )
ΔH = energy of product - energy of reactant
= -15 - 0 = - 15 kJ
ΔH is negative so reaction is exothermic .
d ) Activation energy = 25 - 0 = 25 kJ .
e ) Energy released = 15 kJ .
A for number 1 and C for number 2 im sorry i dont know the rest. :3
The correct answer would be C, vacuole.
Answer:
According to the proton theory of acids and bases by J. Brønsted and T. Lowry, the acid is<u> proton donor</u>.
Explanation:
According to the Bronsted lowry concept an acid is substance that gives protons or hydrogen ion while,
Base is substance that accept hydrogen ion or proton.
Consider the following example:
NH₃ + HCl → NH₄⁺ + Cl⁻
In this example HCl is Bronsted lowry acid it gives H⁺ while ammonia is Bronsted lowry base because it accept H⁺.
This also gives the concept of conjugate acid and base. In given example Cl⁻ is conjugate base of HCl while NH₄⁺ is conjugate acid of ammonia.
