Answer:
376.56
Explanation:
using the formula q=mcΔT, where m=15g, C=4.18J/g°C and ΔT=6.0°C
Answer:
The wavelength the student should use is 700 nm.
Explanation:
Attached below you can find the diagram I found for this question elsewhere.
Because the idea is to minimize the interference of the Co⁺²(aq) species, we should <u>choose a wavelength in which its absorbance is minimum</u>.
At 400 nm Co⁺²(aq) shows no absorbance, however neither does Cu⁺²(aq). While at 700 nm Co⁺²(aq) shows no absorbance and Cu⁺²(aq) does.
Answer:
The answer is HCl → H 2 O H+ + Cl.
Mass per unit volume is nothing but density of an body density = Mass/Volume. hope this helps. :)
Ocean-dwelling I would say.
