The correct answer among the choices is the first option. The movement of the molecules inside a block of iron when it is heated is affected by the movement being faster as compared to the first conditions. Temperature is said to be directly proportional to kinetic energy which means as temperature increases, the kinetic energy also increases. Therefore, molecules now are moving faster.
Answer:
The answer to your question is 12
Explanation:
Data
Number of electrons in Phosphorus 3+ ion
Process
1.- The sign of the number after the name indicates if the element has lost or gained electrons.
If the sign is positive the element has lost electrons
If the sign is negative the element has gained electrons.
2.- Phosphorus atomic number is 15, then the number of electrons in Phosphorus 3+ will be 12, in this example, Phosphorus lost 3 electrons.
Answer:the answer would be a because that's what it would talk about and is the correct answer
Explanation:yes it is correct just answer it trust me
The molecules and atoms vibrate faster. As atoms vibrate faster the space between atoms also increases.
Answer:
Both are B. Hope this helps.
