It’s called neutralization. The alkali has neutralized the acid by taking away the H+ ions and then turning them into water.
A) Since both are carbons with the only difference in the number of neutrons,
They are called Isotopes
B) Carbon - 12 has 6 protons and 6 neutrons, while Carbon-13 has 6 protons and 7 neutrons,
Therefore Carbon-12 and Carbon-13 have the same number of protons
C) Carbon - 12 has 6 protons and 6 neutrons, while Carbon-13 has 6 protons and 7 neutrons,
Therefore Carbon-12 and Carbon-13 has different numbers of neutrons
D) Sorry i don't know any uses of Carbon-12 and Carbon-13, you might have to research to get it.
E or F) Sodium 23 has 12 neutrons and 11 electrons, because its mass number 23, atomic number is 11 and since protons and electrons count is same, the number of neutrons = mass number - atomic number = 23 - 11 = 12 neutrons
Happy to help :)
If you need any more help, feel free to ask
The periodic table is an important but rather dry scientific tool. It lists all the chemical elements, ordered by their atomic numbers. Elements with similar behavior are grouped in the same column (called a group), with metals generally on the left and non-metals (gases) on the right. Rows are called “periods” - hence, periodic table.
Is this what you looking for ???

Answer:
1) Condensation.
2) See below.
Explanation:
1) The warmer water vapour from the surroundings came into contact with the cooler inner surface of the glass jar and condensed, forming the water droplets (water vapour) on the inside of the glass jar.
2) As condensation occurs, condensed water vapour will drip into the water solution in the glass jar, causing the water to rise in the glass jar.
