Following reaction shows the preparation of
Nitrile from
Amide. In this reaction
Thionyl chloride is reacted with Amide, which produced nitrile along with
SO₂ and
HCl gas. The
importance of this reaction is the removal of byproducts (i.e SO₂ and HCl). As both SO₂ and HCl are gases so
no extra workup is required to remove them. The mechanism of reaction is as follow,
Answer:
20 pretzels.
Explanation:
So in the first bag there at 64 pretzels in 16-ounces.
We can divide both these numbers by 16, to get 4 pretzels per ounce.
If we multiply both numbers by 5, we get 20 pretzels per ounces.
So, 20 pretzels i5-ounce bag.
First convert the 112 km/hr ratio into m/s (meters per second). To do this you multiply 112 km with 1000 m/km (since there's 1000 m in one km). You get 112000 m. Then multiply 1 hr with 60 min/hr (since there's 60 min in one hr. You get 60 min, but you want seconds, so multiply 60 min with 60 s/min to get 3600 s. There you go! Your answer is the speed of 112000m/3600s, but you can simplify that to 31.11m/s (since the answer should be in ? meters per 1 second.
Also, the "100-m-distance" part of the question is just to throw you off, because one particular speed obviously stays constant over any distance. Hope that helps :)
