Explanation:
I took the test eWe
An ions have charge and it gains or loses electrons.
Answer:this case, the mass is 2.0g, the specific heat capacity of water is 4.18J/g/K, and the change in temperature is 5.0°C=5K , therefore the energy needed to raise it is: 5×2×4.18=41.8J
Explanation:
I think it's reactivity. but i'm not sure.
