Incomplete combustion is formed like: hydrocarbon + oxygen-> carbon + carbon monoxide + water!
Answer:
Gases in Earth's atmosphere form a protective layer
Nitrogen, oxygen and ozone molecules in the upper atmosphere and stratosphere absorb ultraviolet light from the Sun, providing a shield that prevents this radiation from passing to the Earth's surface.

Answer:
4.90% is approximately the new Dextrose concentration.
Explanation:
Volume by Volume percent is given by ;

Volume percentage of dextrose solution = 5%
In 100 mL of solution 5 ml of dextrose is present.
Now, volume sterile water added was equal to the 40% of volume of dextrose volume.
So, volume of the sterile water added = 
Total volume of the solution after addition of water = 100 mL + 1 mL = 102 mL
New concentration of dextrose will be;


4.90% is approximately the new Dextrose concentration.

Answer:
Δ h = 2958.9 kJ/kg
Explanation:
initial state
T₁ = 50⁰C
P₁ = 1 bar
from steam table , Enthalpy at 50⁰C and 1 bar
h₁ = 208.785 kJ/kg
final state
T₂ = 350⁰C
P₂ = 5 bar
from steam table , Enthalpy at 350⁰C and 5 bar
h₂ = 3167.75 kJ/kg
change in entalpy for the process
Δ h = h₂ - h₁
= 3167.75 - 208.785
Δ h = 2958.965 kJ/kg
the change in enthalpy is equal to Δ h = 2958.9 kJ/kg
