Dmitri Mendeleev is the answer
Answer:
Protons and Neutrons
Explanation:
The sum of number of protons and the number of neutrons is equal to the mass of an element. Mathematically, it can be given as :
M = P + N
Also, the atomic mass can be calculated by the sum of the element's isotopes as isotopes have slightly different mass numbers.
Hence, protons and neutrons add together to determine the atomic mass.
The ccorrect answer is C a generator tubrine
Answer:
6 moles of CuCl₂ will produced 4 moles of AlCl₃ .
Explanation:
Given data:
Moles of CuCl₂ = 6 mole
Moles of AlCl₃ produced = ?
Solution:
3CuCl₂ + 2Al → 2AlCl₃ + 3Cu
Now we will compare the moles of CuCl₂ with AlCl₃ .
CuCl₂ : AlCl₃
3 : 2
6 : 2/3 ×6 = 4 mol
So, 6 moles of CuCl₂ will produced 4 moles of AlCl₃ .
I think the answer is D in my opinion
