Answer:
<h2>The answer is 8 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 16 g
volume = 2 cm³
The density is
We have the final answer as
<h3>8 g/cm³</h3>
Hope this helps you
The answer is B. its take a reaction to form gas.
Answer:
a) 1.269 × 10^-7 m
b) This wavelength occurs in the ultraviolet region of the electromagnetic spectrum
Explanation:
The energy required to break the bond= energy of the incident photon
E= 941 × 10^3/6.02 × 10^23 = 1.56 ×10^ -18 J
From
E= hc/λ
h= Plank's constant
c= speed of light
λ= wavelength of incident photon
λ= hc/E
λ= 6.6 ×10^-34 × 3 ×10^8/1.56 ×10^ -18 J
λ= 1.269 × 10^-7 m
b) This wavelength occurs in the ultraviolet region of the electromagnetic spectrum
Answer:
(A) The statement is false. The starting material is favored at equilibrium
Explanation:
As we know that type of reaction is predicted by value Gibbs free energy.
ΔG >0 It means that reaction is non spontaneous and favors the reactant of the reaction.
ΔG <0 It means that reaction is spontaneous and favors the product of the reaction.
As we know that
ΔG = ΔH -T ΔS
Here given that Assume the entropy term is small compared to the enthalpy term so ΔS = 0
⇒ ΔG = ΔH
Given that
ΔH o = 65 kJ/mol,
ΔG = ΔH = 65 kJ/mol
ΔG >0 It means that reaction is non spontaneous and favors the reactant of the reaction.
So the option A is correct.
(A) The statement is false. The starting material is favored at equilibrium.
