First option is the right answer Goodluck
Answer:
Your answer would be B because In the first move energy was absorbed, because when energy is gained an electron moves to a higher energy level in the second move energy will be released because that is how an atom moves to a lower energy level. The jump from level 1 to 4 was bigger than the drop from 4 to 2, because in the first move it moved from more orbitals. thus describing the the energy in the first move had a far energy released in the second move.
The statement that "substance A is rice, and substance B is sugar" is correct.
WHAT IS A MIXTURE?
- A mixture in chemistry is a substance that contains two or more different substances.
- One notable characteristics of a mixture is that it can easily be separated using physical means.
According to this question, a mixture contains two substances A and B. Water is added to this mixture for easy separation.
- Substance A is filtered out. This means that substance A is a solid that is insoluble in water. This substance is RICE.
- The remaining liquid is heated to remove the water content leaving a residue of substance B. This shows that substance B is also a solid but soluble in water. SUGAR best fits this description.
Therefore, in the mixture of two substances A and B, substance A is rice, and substance B is sugar.
