Answer:
1.85 × 10⁸ L
Explanation:
Coal power plants burn large amounts of coal, C(s), in an O₂(g) atmosphere to generate electricity. The chemical reaction responsible for producing this energy is shown below:
C(s) + O₂(g) → CO₂(g)
Determine the volume of CO₂ in liters produced when 100 metric ton of C(s) is completely burned in an O₂ atmosphere. The density of CO₂ is 1.98 kg/m³ (1 metric ton = 1000 kg: 1 m³ = 1000 L)
We can establish the following relations:
- 1 metric ton = 1000 kg
- 1 kg = 1000 g
- The molar mass of C(s) is 12.01 g/mol
- The molar ratio of C(s) to CO₂(g) is 1:1
- The molar mass of CO₂(g) is 44.01 g/mol
- 1.98 kg of CO₂(g) occupy a volume of 1 m³ (density = 1.98 kg/m³)
- 1 m³ = 1000 L
The volume of CO₂ produced when 100 metric ton of C(s) react is:
The answer is- Volume of flask = 247.8 
or 247.8 mL.
Density (d) is defined as mass of substance divided by its volume. Thus, if mass and density are known, then Volume can be determined.
What is the formula of volume in terms of density?
- Let mass of substance be 'm' and volume be 'V'. Thus, as per the definition of density, it is expressed as-
Thus, volume can be expressed as-
- Now, mass of empty flask = 241.3 g and the mass of (flask + Water) = 489.1 g.
Thus, mass of water = 
.
- Thus, mass of water = 247.8 g and density of water =
. Its volume is calculated as-
- Hence, volume of flask = 247.8 or 247.8 mL.

Answer:
it will sink to the bottom
Explanation:
if it has a higher density than the water then it will sink.
A double bond consists of one sigma bond and one pi bond.
Therefore Option C is the correct answer.
<h3>What is a Double Bond ?</h3>
A bond in which 4 electrons are shared between a [pair of atoms is called a double bond , higher amount of energy is required to break a double bond.
A double bond consists of one sigma bond and one pi bond.
