Depending on the balloon, the surface will cause friction between the two and oxygen molecules will fuse together to create a sticky sensation
A . A person Jumping represents an unbalanced force.
<u>Explanation:</u>
If equal amount of force applied on any object from both the directions, then the object will not move and so the force is a balanced force.
If an unequal amount of force on an object from both sides then the object will move in the opposite direction of the maximum force applied, so it is called as an unbalanced force.
- When the force is unbalanced then its velocity will change, so options C and D are omitted.
- In Option B the vase is sitting on a table, just kept so there is no action of any unbalanced force.
- But a person jumping represents an unbalanced force, since the person do not jump with constant velocity and it will vary.

Answer:
2.40 × 10²³ Atoms of Hydrogen
Solution:
The number of hydrogen atoms in C₃H₈O₃ are calculated as;
As, there are eight hydrogen atoms per molecule of C₃H₈O₃, therefore the number of hydrogen atoms per mole of C₃H₈O₃ are calculated as;
1 mole C₃H₈O₃ contains = 6.022 × 10²³ Molecules of C₃H₈O₃
So,
0.05 mole C₃H₈O₃ will contain = X Molecules of C₃H₈O₃
Solving for X,
X = (0.05 × 6.022 × 10²³) ÷ 1
X = 3.011 × 10²² Molecules of C₃H₈O₃
As,
1 Molecule of C₃H₈O₃ contains = 8 Atoms of Hydrogen
So,
3.011 × 10²² Molecules of C₃H₈O₃ will contain = X Atoms of Hydrogen
Solving for X,
X = (3.011 × 10²² × 8) ÷ 1
X = 2.40 × 10²³ Atoms of Hydrogen
