A question that can be tested scientifically are questions that can be answered through observations or through a well designed experiment that can provide evidence.
The balanced chemical equation for the reaction is:
2AgNO3 + CaCl2 --> 2AgCl + Ca(NO3)2
Moles of CaCl2 reacted = conc * vol = 0.100 * 3.00 = 0.300 moles
Reaction ratio between CaCl2 and AgNO3 is 1:2. Hence moles of AgNO3 = 0.300 * 2 = 0.600 moles
Volume of AgNO3 = moles / conc = 0.600 / 0.100 = 6.00L
Of course the easy shortcut is that because both solutions are the same concentration you could just multiply 3.00 * 2, however this explanation should reason it out more clearly. Hope I helped you :)
Answer:
8 grams.
Explanation:
When solving this type of problem, you need to find how many grams 4.0% of 200g will be equivalent to. You can do this by setting up an equation as such:
200 grams ×0.04 = 8 grams. (0.04 is equivalent to 4%)
I need this answer as well. Please like this or comment when you find this out. Thank you :)
the continuous spectrum of white light only deals with the frequencies and wavelengths of colors associated with the rainbow. and the emission spectrum is I think deals with the colors, frequencies, and wavelengths that are released by a particular atom.
