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.

#SPJ1
The following substance must be an A. Compound.
Answer is: fatty acids of short (C4-C6) and medium (C8-C10) chain fatty acids (SCFAs and MCFAs) solubilize in intestinal fluids and are absorbed directly into the portal system.
Fatty acid with ten carbon atoms made medium chain triglycerides, that we also consume by food and get energy by breaking bonds between and oxidizing carbon atoms.
Answer:
Number of moles = 0.87 mol
Explanation:
Given data:
Mass of calcium = 34.8 g
Number of moles = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of calcium = 40 g/mol
By putting values,
Number of moles = 34.8 g/ 40 g/mol
Number of moles = 0.87 mol
Answer:
atomic mass
