Answer:</h3>
Velocity is 1 m/s
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of the kiddy train is 1000 kg
- Radius of the curve is 5.0 m
- Centripetal force is 2000 N
We are required to determine the maximum speed of the train.
- Centripetal force refers to the force experienced by an object in a circular motion towards the center of a circular path.
- It is calculated by the formula;
- , where m is the mass, v is the velocity and r is the radius of the circular path.
- Therefore, using the formula we can find the maximum speed.
Therefore, the maximum speed of the train is 1 m/s
I need the graph to answer your question
Answer:
Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
Explanation:
Answer:
cinnamic acid - 150 mg
cis-stilbene - 100 μL
trans- stilbene - 100 mg
pyridinium tribromide - 200-385 mg
For this data:
moles of cinnamic acid = 0.150 g/148.16 g/mol = 0.001 mols
Theoretical mass of dibromoproduct formed = 0.001 mol x 307.97 g/mol = 0.312 g
cis-stilbene (100 ul = 0.1 ml)
moles of cis-stilbene = 0.1 ml x 1.01 g/mol/180.25 g/mol = 0.00056 mols
Theoretical mass of dibromoproduct formed = 0.00056 mol x 340.05 g/mol = 0.19 g
trans-stilbene
moles of tran-stilbene = 0.1 g/180.25 g/mol = 0.00055 mols
Theoretical mass of dibromoproduct formed = 0.00055 mol x 340.05 g/mol = 0.19 g

Answer:
4
Explanation:
Given reaction is
2A + 3B -> 2C
From the above reaction for every 2 moles of A, 2 moles of C is formed and therefore for every mole of A reacted, 1 mole of C is formed
Now in this case we have 4 moles of A and excess amount of B
So in this case the limiting reagent is A and the excess reagent is B
As in this case A is the limiting reagent so for 4 moles of A reacted, 4 moles of C is formed
But formation of 4 moles of C is just expected because it is just the maximum amount of C formed as during the reaction there can be losses as well if the reaction is not done properly
