Answer:
5.9405*10^14 Hz
Explanation:
Remember the equation c=v*λ
v=frequency
λ=wavelength
By manipulating the equation, we can get it in terms of frequency:
c/λ=v
Now convert wavelength to meters (1nm=m*10^-9)
5.05*10^-7m (2 decimal places were shifted to make the number between 1-10, hence the -7 exponent)
Use the manipulated equation:
(3.00*10^8)/(5.05*10^-7), which yields:
5.9405*10^14 Hz (or s^-1)
Eutrophication will happen. Aerobic bacteria in the water will decompose the fertilizer and release a tonne of minerals that algae found in the water will then use.
The bacteria will have used up a lot of oxygen and the algae, while respiring will also use up a lot.
Main Answer: The resultant solution will have 0.125M of HCl.
Explanation:
Given:
Volume of NH3 V1= 25ml = 0.025lit
Molar concentration of NH3 M1= 0.1M
It is titrated with HCl
Molar concentration of HCl M2= 0.25M
Volume of HCl V2= ?ml
At equilibrium,
M1V1 = M2V2
V2 = M1V1/M2
V2 = (0.1*0.025)/0.25
V2= 0.01lit =0.01*1000 = 10ml
Number of moles = M2*V2 = 0.25 * 0.01 = 0.0025
Now 10ml of HCl is added.
then,
V2 = 10 + 10 = 20ml
Molar concentration of HCl = number of moles/Volume
= 0.0025/0.02
= 0.125M
The resultant solution will have 0.125M of HCl.

Answer:
Explanation:
a) 3.00 mol Cu x 2 mol Ag/ 1 mol Cu = 6 mol Ag
b) 3.00 mol Cu x 2 mol Ag/1 mol Cu x 107.87g Ag/ 1 mol Ag = 647.22g Ag
c) 3.00 mol Cu x 1 mol Cu(NO3)2/ 1 mol Cu = 3 mol Cu(NO3)2
d) 3.00 mol Cu x 1 mol Cu(NO3)2/ 1 mol Cu x 187.54g/ 1 mol Cu(NO3)2 =562.644g Cu(NO3)2
The phase change in which the water molecules become most orderly is the freezing. This is the process of changing water as liquid to its solidified form. The process of freezing is an exothermic which means that for this to occur, heat should be removed from the system.
