Answer:
Option D is good to go!
Explanation: as per the reactivity series more reactive substances will react with the counterpart substance.The most reactive substance here is calcium while the least reactive is aluminium, the magnesium comes in between.As per their reactivity, these substances will react with oxygen.
Explanation:
The question is confusing and all the answers are not there but it is B C and D
Answer:
<u></u>
Explanation:
Normally, in the neutralization reactions, that is how the reactions between and acid and a base are called, you assume additive volumes.
Additive volumes means that the <em>volume</em> of the final <em>solution</em> is equal to the sum of the separate volumes of the two solutions that are mixed.
It is not totally accurate, but it is a good approximation and for lack of additional data it is what is used.
Then, assuming additive volumes:
- Total volume of the solution = 100 mL + 250 mL = 350 mL.
