Displacement is the distance and direction of an object's change in position from the starting.
Hence option B is correct.
Hope this helps!
I attached a photo of my work below. Please tell me if I got it wrong; hope you got a good score on your assignment! ^v^
Answer:D and C sorry if im wrong
Explanation:
1 mole Fe produces 1 mole Cu
<span> molar mass of Fe is 55.8 g / mole
answer: </span><span>55.8g</span>
The first thing we need to do here is to recognize the unit of molarity and the units of the given percentage of nitric acid.
Molarity is mol HNO3 / L of solution. This is our aim
The given percentage is 0.68 g HNO3/ g solution
multiplying this with density to convert g solution into mL solution and dividing with the molecular weight of HNO3 (63 g/mol) to convert g HNO3 to mol. Therefore we obtain
0.016 mol/ mL or 16.23 mol/ L (M)
