5. 1 hydrogen, 1 Nitrogen, 3 oxygen
the answer is c
Explanation:
because c has all elements mixed together
Answer:
The answer to your question is below
Explanation:
Data
Aqueous acetic acid
Aqueous barium hydroxide
Formula
Acetic acid CH₃CH₂COOH
Barium hydroxide Ba(OH)₂
Neutralization reaction
CH₃CH₂COOH + Ba(OH)₂ ⇒ Ba( CH₃CH₂COO)₂ + H₂O
Barium acetate + H₂O
Barium acetate = Ba( CH₃CH₂COO)₂ = Ba(C₃H₅O₂)₂
Mass Number quantifies the number of protons and neutrons in the atom. Electrons are so small that they do not even matter in the calculation. Protons and Neutrons are approximately 1 A. Atomic Number refers to where the atom is on the periodic table, such as Hydrogen being Atomic Number 1, but also quantifies the number of protons. In your situation the atomic number is 32 meaning it is Germanium but also meaning it has 32 protons. When we add the number of protons and number of neutrons to find the mass number we do 32 (protons) + 31 (neutrons) to get a total mass number of 63. 63 is your answer.
Decreases by 1 (lol i guesses and got it right on castle learning)
