Answer:
If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.

Answers:
1.
The mole ratio of AlCl₃ to Cl₂ is 2 : 3. This means for production of every 2 moles of AlCl₃ 3 moles of Cl₂ is consumed. Hence, if 3 moles of AlCl₃ is produced then Cl₂ consumed is,
= 3 × 3 / 2
= 4.5 moles of Cl₂
2.
Mole ratio of C₃H₈ to CO₂ is 1 : 3.
Hence, 0.5 moles of C₃H₈ will produce 1.5 moles of CO₂.
Also,
At STP one mole of an ideal gas occupied 22.4 L of volume. Hence, 1.5 moles of CO₂ gas will occupy,
Volume = 1.5 mol × 22.4 L/mol
Volume = 33.6 L of CO₂
The formula for calculating the density (p)=m/v
m:mass
v:volume
<u>Explanation:</u>
In the question above,given that
<u>mass of water (m)</u> =100 g
<u>Volume of water in a beaker (v)</u>=100 mL
<u>The Density of the water(p</u>)=m/v=100 g/100 mL= 1 g/mL
The answer is (B) 1 g/mL
