Answer:
Sodium is more reactive than lithium because as we move down a group it is easy to lose electrons as the number of shells increases and nuclear charge decreases. As valence electrons take part in chemical reaction and its easier to lose electrons as we move down a group chemical reactivity increases. Therefore, sodium is more reactive than lithium.
Explanation:
I gotcha I searched it up
If they are in the same group they have the same valence electrons but since I cannot see what you’re talking about I’m not sure what your question is
Answer:
a
Explanation:
Because the mass would stay the same and the flavor did not change and neither did the color so the shape is the only thing that changed
Hello! Specific heat is the amount of energy required by known amount of substance to raise its temperature by one degree celsius. In our question it is given that 2000J energy when supplied to 125 g of unknown substance raised its temperature by 18 oC. So, The specific heat is calculated as follow;
