Yes if you build it right it could easily work, i suggest using tape or rope if it's allowed to help support the structure....
Lol now way he answers this
Answer:
v = 1.5 m/s
Explanation:
Given that,
Distance covered by a person, d = 105 m
Time taken, t = 70 s
We need to find the average speed of the person. We know that the average speed is given by :
So, the average speed of the person is equal to 1.5 m/s.
From the equation it is evident that 2 moles of Sodium metal produces 1 mole of hydrogen gas.
At STP 1mole of any gas occupies a volume of 22.4 liters.
Therefore, 7.80 gives---(7.80×1)/22.4 moles= 0.3482 moles
Since the mole ratio of Sodium to hydrogen is 2:1, then the number of moles of sodium that reacted is given by the following expression.
(0.3482×2)/1 moles which gives 0.6964 moles.
The atomic mass of sodium is 23 thus the mass of sodium that reacted is given by:
mass=no. of moles×RAM
0.6964×23= 16.02 grams.
