The intended sense is that of a reaction that depends on absorbing heat if it is to proceed. The opposite of an endothermic process is an exothermic process, one that releases "gives out" energy in the form of heat
Answer:
The proper matching is given below.
Explanation:
a Separate molecules by size size exclusion chromatography
b Separate molecules by charge Ion exchange chromatography
c The stationary phase has a covalently bound group to which a protein in the mobile phase can bind. Affinity chromatography
d uses mobile phase and stationary phase to separate protein Size exclusion chromatography
e The stationary phase contain cross linked polymers with different pore size
Size exclusion chromatography
f can separate molecules based on protein ligand binding Affinity chromatography
g The stationary phase may contain negatively or positively charged groups
ion exchange chromatography
Carbon can be used in fuel
B). 2 Hours
Explanation if the older brother can run 6 MPH and it’s takes him a hour and twenty minutes you automatically can say it’s at least 6 miles then you have to see how many he can run in 20 minutes which is roughly 2 miles so that would mean he run for 8 miles if the younger brother can run 4 MPH then you just have to add that by 2 too see how long it will take to run 8
The changes in matter/energy can be classified as follows:
- Physical changes - Crystallizing salt from seawater
- Chemical changes - ripening fruit
- Nuclear changes - production of elements in the stars
<h3>What are physical, chemical and nuclear changes?</h3>
Matter and energy undergo physical, chemical and nuclear changes.
Physical changes are changes in which no new product is formed.
Chemical changes are changes in which no new product is formed.
Nuclear changes are changes in which no new product is formed.
Examples of each of the given changes is as follows:
- Physical changes - Crystallizing salt from seawater
- Chemical changes - ripening fruit
- Nuclear changes - production of elements in the stars
Therefore, matter/energy undergo changes.
