Answer:
1.) 274.5v
2.) 206.8v
Explanation:
1.) Given that In one part of the lab activities, students connected a 2.50 µF capacitor to a 746 V power source, whilst connected a second 6.80 µF capacitor to a 562 V source.
The potential difference and charge across EACH capacitor will be
V = Voe
Where Vo = initial voltage
e = natural logarithm = 2.718
For the first capacitor 2.50 µF,
V = Vo × 2.718
746 = Vo × 2.718
Vo = 746/2.718
Vo = 274.5v
To calculate the charge, use the below formula.
Q = CV
Q = 2.5 × 10^-6 × 274.5
Q = 6.86 × 10^-4 C
For the second capacitor 6.80 µF
V = Voe
562 = Vo × 2.718
Vo = 562/2.718
Vo = 206.77v
The charge on it will be
Q = CV
Q = 6.8 × 10^-6 × 206.77
Q = 1.41 × 10^-3 C
B.) Using the formula V = Voe again
165 = Vo × 2.718
Vo = 165 /2.718
Vo = 60.71v
Q = C × 60.71
Q = C
The correct option is A.
Elements are substances that are made up of atoms of the same type., while compounds are made of two or more atoms of different types.
Some common examples of elements are Iron, Sodium, oxygen, Hydrogen, while NaCl ( Sodium Chloride), Water (H_2O) , Ammonia (NH_3) are compounds.
It can be seen that the compounds are composed of atoms of different substances.
Chlorine is a diatomic molecule, where two Chlorine atoms are bonded by a covalent bond. Since both atoms in a Chlorine molecule are the same, it cannot be called a compound.
Hence Chlorine, though it has more than one atom in its molecular form, is still called element.
