Answer:
the reactivity of alkaline earth metals increases from top to the bottom of the group, that's because the atoms get bigger from the top to the bottom so the valence electrons are farther from the nucleus.
Answer:
atoms have no overall charge. this is because they contain equal numbers of positive protons and negative electrons

Answer : The reaction rate at are
Solution : Given,
Mass of tablet = 1000 mg
Volume of water = 0.200 L
The given formula will be,
Now we have to calculate the reaction rate at different temperatures and reaction time.
Therefore, the reaction rate at are
