Answer:
Option (B) 3.
Explanation:
In the model represented above, the two extreme represent carbon atoms since no other group are attached to it. The joint at the middle also represent carbon atom.
Thus, we can write a more simplify illustration for the model above as
C—C—C
From the above illustration, we can see that the model contains 3 carbon atom.

Answer:
1.35 g
Explanation:
Data Given:
mass of Potassium Permagnate (KMnO₄) = 3.34 g
Mass of Oxygen: ?
Solution:
First find the percentage composition of Oxygen in Potassium Permagnate (KMnO₄)
So,
Molar Mass of KMnO₄ = 39 + 55 + 4(16)
Molar Mass of KMnO₄ = 158 g/mol
Calculate the mole percent composition of Oxygen in Potassium Permagnate (KMnO₄).
Mass contributed by Oxygen (O) = 4 (16) = 64 g
Since the percentage of compound is 100
So,
Percent of Oxygen (O) = 64 / 158 x 100
Percent of Oxygen (O) = 40.5 %
It means that for ever gram of Potassium Permagnate (KMnO₄) there is 0.405 g of Oxygen (O) is present.
So,
for the 3.34 grams of Potassium Permagnate (KMnO₄) the mass of Oxygen will be
mass of Oxygen (O) = 0.405 x 3.34 g
mass of Oxygen (O) = 1.35 g

Based on this theory, a knowledge considered to be true if the knowledge kehoren with the knowledge that exists and has been proven to be true. In the study of mathematics this is usually called the deductive nature.
2. Correspondence Theory (Theory of corespondence)
Based on this theory, a knowledge considered to be true if the knowledge of having a relationship with a reality that is true. This theory is based on the empirical fact that knowledge is true if there are facts that support that is true knowledge. Thus the truth here is based on inductive inference.
3. Pragmatic Theory (Theory of Pragmatism)
According to this theory, knowledge is said to be true if the knowledge is seen practically completely or have properties that true practicality. Followers of this theory argue that knowledge is true if it has keguanaan practical<span>.</span></span>
