Answer:
The answer to your question is: 17.26% of carbon
Explanation:
Data
CxHy = 0.2121 g
BaCO₃ = 0.6006 g
Molecular mass BaCO₃ = 137 + 12 + 48 = 197 g
Reaction
CO₂ + Ba(OH)₂ ⇒ BaCO₃ + H₂O
Process
1.- Find the amount of carbon in BaCO₃
197 g of BaCO₃ --------------- 12 g of Carbon
0.6006 g ---------------- x
x = (0.6006 x 12) / 197
x = 0.0366 g of carbon
2.- Calculate the percentage of carbon in the organic compound
0.2121 g of organic compound --------------- 100%
0.0366g -------------- x
x = (0.0366 x 100) / 0.2121
x = 17.26%

Explanation:
Plants serve as the main source of nutrition for humans as well as provide many products for human use, such as firewood, timber, fibers, medicines, dyes, oils, and rubber.
Plants are multicellular eukaryotic organisms whose mode of nutrition is mainly autotrophic.
Plants play many important roles in life more especially that of producing food on which many other organisms depend on.
Some of the important ways by which plants support human life include:
- Provision of food: plants trap the energy of the sunlight and through the process of photosynthesis produce food on which other living organisms such as animals depend on.
- Provision of oxygen: during the process of photosynthesis, plant release oxygen into the atmosphere which is needed by animals for respiration.
- Recycling of water: through the process of transpiration occurring in leaves of plants, water is recycled in nature.
- Provision of other products such as timber, fibers, medicines, dyes, oils, and rubber.
Therefore, plants serve as the main source of nutrition for humans as well as provide many products for human use, such as timber, fibers, medicines, dyes, oils, and rubber.

Explanation:
Answer : The vapor pressure of water at 
is 1.01 atm.
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
or,
where,
= initial pressure = ?
= final pressure = 750 torr = 0.987 atm (1 atm = 760 torr)
= initial volume = 1.95 L
= final volume = 2.00 L
Now put all the given values in the above equation, we get:
Therefore, the vapor pressure of water at is 1.01 atm.
