Answer:
A flame is defined as the gaseous part of the fire which is visible to us. A flame is created due to the high exothermic reaction.
Two types of flames based on the amount of oxygen available are:
- Non-luminous or blue flame: In this type of flame the amount of oxygen is sufficiently large and it gives blue flame. For example: flame of Gas stove.
- Luminous flame: In this type of flame, the oxygen availability id not sufficient for the complete combustion and left unburnt carbon particles that forms yellow light flame. For example: kerosene lamp.
Answer:
The total number of atoms when glucose and oxygen reacts stays the same when carbondioxide and water are produced.
Explanation:
Chemical reaction:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
We can see that the number of atoms of each element remain same on both side of reaction so law of conservation of mass is followed by this reaction. Six number of carbon atoms twelve number of hydrogen atoms and eighteen number of oxygen atoms are present on both side.
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration.
A person would weigh more on Neptune than on planet earth because the gravitational field strength is stronger on Neptune.
Answer:
Explanation:
Hello,
At first, we compute liquid-phase molar fractions:
Now, by means of the fugacity concept, for hexane, for instance, we have:
In this manner, at 25 °C the vapor pressure of hexane and heptane are 0.198946 atm and 0.013912 atm repectively, thus, the total pressure is:
Finally, from the hexane's fugacity equation, we find its mole fraction in the vapour as:
Best regards.
Answer:
True
Explanation:
Both work because an element would be pure and compounds can be split into elements. This will work unless the substance isnt chemcially pure, but in this case it is so the answer would be true.
