Refer to the experiment below: soil+baking soda+water → creates gas bubble

soil+vinegar → no gas bubble

The only possible explaination is that the baking soda reacts with acids in the soil. however,

alkaline+acids→salt+water

which doesn't creates gas, am I wrong?

I think you are correct with your answer.

Explanation:

But I don't think that the explanation is correct because I think that it is the formation of both baking soda and water that makes it work...Vinegar doesn't make gas bubbles maybe because it hasn't reacted or maybe because it is not the right ingredient for the solution you are looking for. Thank you for the questionAm not sure I really helped in your question but thank you..

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
