Hello!
The part of the carbon cycle where humans had the greatest impact is the return of CO₂ to the atmosphere by burning of ancient organic matter.
The ancient organic matter is also called Fossil Fuels. Some Fossil Fuels are Petroleum and Coal. Fossil Fuels are used to power our society and are burned to provide energy for power plants and vehicles, and by burning them, Carbon Dioxide (CO₂) is produced, increasing the natural concentration of this compound in the atmosphere.
Have a nice day!
They are kind of opposite processes. Chemical synthesis is execution of chemical reactions to make products. Like you take two substances, you put them together, they react and you have new a substance. For example.
here Sodium and Chlorine react to make a new substance which is Sodium Chloride.
Chemical decomposition is process of seperating a substance to different substances. There is a substance by a reaction this substance becomes two substances, Like : XY -> X+Y For example :
1. The reaction is exothermic.
2. I know this because the delta H is a negative number. (-802.4 kJ)
3. This means that this reaction releases heat.
Answer:
4 enzymes responsible for digestion:
1. Salivary amylase ---- substrate: Starch ---- end-product: Maltose
2. Lipase ---- substrate: Lipids (fats and oils) ---- end-product: Fatty acids and glycerol
3. Maltase ---- substrate: Maltose ---- end-product: Glucose
4. Protease ---- substrate: Protein ---- end-product: Amino acids
Answer:
Celsius +273.15
Explanation:
The two scales have the same size degree, but Kelvin is an absolute scale based on absolute zero while 0° in Celsius is based on the melting point of water. So, in order to convert from Celsius degrees to Kelvin we only need to add 273.15 to the given temperature:
K= °C + 273.15
