Answer:
The answer to your question is: letter E, 1.77 L of 1.55 M Ba(NO3)2
Explanation:
Formula
Molarity = 
moles = Molarity x volume (L)
a. 2.58 L of 0.0250 M Ba(NO3)2
moles = (0.025) (2.58)
moles = 0.065 M
b. 19.23 mL of 8.5 × 10−2 M Ba(NO3)2
moles = (8.5 x 10 ⁻²) (0.01923)
moles = 0.0016
c. No right answer.
d. 26.20 mL of 2.21 M Ba(NO3)2
moles = (2.21)(0.0262)
moles = 0.058
e. 1.77 L of 1.55 M Ba(NO3)2
moles = (1.55)(1.77)
moles = 2.74 This solution needs the greatest concentration of
Ba(NO₃)₂
The primary difference between a hypothesis and a theory is that a hypothesis is falsifiable but a theory has been proven to be correct. An hypothesis is a proposed explanation put forward on the basis of limited evidence as a commencement point for further investigation, at the end of the investigation the theory may not be accepted if it failed to meet some criteria. A theory is a proven system of ideas used to explain a particular phenomenon.
Answer:
Refracted
Explanation:
White light refracts when it passes through a prism. Each wavelength refracts at a different angle, and the emergent light forms a rainbow.
