Answer:
Maximum acceleration of the truck is 5.25 m/s^2
Explanation:
To find the maximum acceleration the truck first we need to calculate friction between truck and wood. Because of wood is not moving, coefficient of c_{s} need to be used for it. Then the formula will be:
1657.62 Newton is the friction.
So force against friction need to be at most 1657.62 N. Then equation will be:
Maximum acceleration of the truck need to be 5.25 m/s^2
Answer : The mass of oxygen involved in the reaction is, 32 grams.
Explanation : Given,
Mass of carbon monoxide = 56 g
Mass of carbon dioxide = 88 g
Molar mass of carbon monoxide = 28 g/mole
Molar mass of oxygen = 32 g/mole
First we have to calculate the moles of carbon monoxide.
Now we have to calculate the moles of oxygen gas.
The balanced chemical reaction will be,
From the balanced chemical reaction, we conclude that
2 moles of CO react with 1 mole of
So, the moles of = 1 mole
Now we have to calculate the mass of oxygen.
Therefore, the mass of oxygen involved in the reaction is, 32 grams.
