So you'll use the formula M1V1 = M2V2
M1= 10 M
V1= unknown
M2= 0.100 M
V2= 500ml
Plug everything in where it belongs and you should get 5ml, but just watch your significant figures.
Answer:
Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances.
I hope it's helpful!
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
