3. The answer is B. 11. This is because there are the same amount of electrons and protons in an atom, and since there are 11 protons, there are 11 electrons.
5. The formula H2O means that there are 2 hydrogen atoms (because the 2 is after the H), and 1 oxygen atom, so the answer is C.
Hope this helps!

fomenos

Answer: Adiabatic process is a process in which <u>heat</u> is constant

Explanation:

The processes in which temperature remains constant is called isothermal process.

The process in which Volume remains constant is called isochoric process.  

The process in which pressure remains constant is called isobaric process.

 The process in which no heat is gained or lost by the system, Hence heat remains constant is called as adiabatic process.

Thus option d) heat is correct

If an atom has an atomic number of 6 and and abdomens mass of 12 how many electrons does it have
Basile [38]
Atomic number refers to the proton number of the atom itself. Number of electrons in an atom (an atom that is not reacted with any other molecules / Just the atom alone), is the same as the number of protons, because each electron has 1 negative charge, and each proton 1 positive charge, where they cancel out on each other to become a neutral charge.

So, when atomic number is 6, proton number is also 6, and number of electrons will also be 6 in that atom.

Hope this helps! :)
