Answer:
<h2>14.05 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>14.05 moles</h3>
Hope this helps you
Answer: A balloon is charged by a process of frictional charging and the object is getting charged by the process of induction.
Explanation:
When two bodies are rubbed against each other, charging by friction or rubbing occurs. The electropositive object loses electrons to electronegative object. Thus, when balloon is rubbed on a wall, it becomes charged.
The charged balloon is able to attract an uncharged object by inducing charge on it without the two objects touching each other. Electrostatic force acts between two charged objects. Charged balloon causes electrons to move at one end thereby inducing opposite charge in the object and thus, charged balloon is able to attract uncharged object.
Answer:
Explanation:
Polar molecules interact with other molecules of similar polarity to form solutions. Non-polar molecules do not interact the same way.
Answer:
453.592 grams
Explanation:
Given
Mass = 1 lb
Required.
Convert to grams using dimensional analysis
Represent 1 lb with x g
In unit conversion, we have that.
1 lb = 453.592 g
So:
Getting the equivalent of lb in g, we have:
x g = 1 lb * (453.592 g/ 1 lb)
x g = 1 * 453.592 g
x g = 453.592 grams
Hence:
The equivalent of 1 lb in grams is 453.592 grams
