Answer:
ΔE(work)= 692 Kj/mole e⁻ = 4.32 x 10²⁴ eV/mole e⁻
Explanation:
ΔE = hc/λ = (6.63 x 10⁻³⁴j·s)(2.99792 x 10⁸m/s)/(1.73 x 10⁻⁷m) = 1.15 x 10⁻¹⁸j/e⁻ x 6.023 x 10²³ e⁻/mole = 691,999 j/mole e⁻ = 692 Kj/mole e⁻ x 6.24 x 10²¹ eV/KJ = 4.32 x 10²⁴ eV/mole e⁻

performed experiments
NO. 11.
Inference
Explanation:
No 10.
in order to prove that Mary Mellon was in fact infected by typhoid proper experiments needs to be carried out.
No. 11
inference means an assumption due to the situation.
Answer:
Yes the reaction occur when aqueous solutions happened
Answer: the original volume was 0.98L
Explanation:
V1 =?
T1 = 22k
V2 = 3.8L
T2 = 85k
V1 /T1 = V2 /T2
VI/22 = 3.8/85
V1 = 22 x (3.8/85)
V1 = 0.98L
Answer: 0.19M
Explanation: 
Using Molarity equation:
= molarity of acid
= volume of acid
= molarity of base
= volume of base
Thus the concentration of the 
solution is 0.19M.
