Answer:
The pencil box is too far away from the magnet to make it move.
Explanation:
The most likely scenario here is that the pencil box is too far away from the magnet to make it move.
A magnet has a force field around it which dictates the region where magnetic influences can be felt when a magnetic body is brought near it.
Outside the force field, a magnet has no effect on a magnetic body.
- Since the magnet is not attracting or repelling the metallic box of pencils, they most be located outside the field of force of the magnet.
- When they are within the force field, repulsion or attraction occurs and the field draws the metal to itself or repel.
Objects that are far away from a magnetic source will feel no effect of the force field of a bar magnet.
Answer:
<h3>The answer is 43.89 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 57.5 g
density = 1.31 g/mL
We have
We have the final answer as
<h3>43.89 mL</h3>
Hope this helps you
Answer
12
Explanation
We have a balanced chemical equation from the question that depicts the formation of water.
2H2+O2-->2H2O,
We can clearly see from the equation that, the formation of 2 moles of water molecules requires the input of 2 moles of hydrogen and 1 mole of Oxygen.
So indirectly, it tells that the moles of water molecules will be double of the moles of Oxygen molecules used in the reaction.
So if we say that 6 moles of oxygen is used and the reaction is going in such a way that hydrogen is not a limiting reactant, then 12 moles of water will be produced.
Hope it help!
