Answer:22.37 mph
Explanation:
100 meters = 0.062137 miles
Assume constant speed over the distance.
0.062137 miles in 10 sec
0.372822 miles in 60 sec = 1 minute
22.36932 miles in 60 minutes
22.37 mph rounded to 2 decimals
Answer:
2.525m/s^2
Explanation:
16.3-6.2 is a difference of 10.1m/s. Dividing this by 4, you get a deceleration of 2.525m/s^2. Hope this helps!

Im not sure, I will get back to you soon
The balanced chemical reaction is:
<span>Zn(s) + 2HCl(aq) = ZnCl2(aq) + H2(g)
</span>
We are given the amount of zinc metal to be used for this reaction. This will be the starting point of our calculations.
5.00 mol Zn ( 1 mol H2 / 1 mol Zn ) = 5.00 mol H2
Therefore, the theortical yield is 5 moles of hydrogen gas.
Any change in temperature or new substance formed is evidence of a chemical reaction, this includes heat, gas or crystallization.
