Answer:
Thermal decomposition
Explanation:
Calcium carbonate can be broken down by heating. The following equation represents this chemical change.
CaCO₃(s) ⇒ CaO(s) + CO₂(g)
The scientific term for this process is thermal decomposition.
- Thermal refers to the fact that heat is required.
- Decomposition refers to the kind of reaction in which a big substance breaks down into smaller substances.
Answer:
2 g
Explanation:
Since both sides have to be equal, add together the weight from the left side to get the total of 137
Subtract 135 from that
The answer is 2.
Answer: Electrons
Explanation: The electrons are found outside the nucleus and orbit it.
25 sugar because the mass should be equal on both sides
