2.67×g of form when 6. 00 moles of bromine react completely.
As per the chemical equation 2 moles of Aluminum react with 3 moles of Bromine to generate 2 moles of Aluminum Bromide
Molecular Weight of Al= 27 g/mol
Molecular Weight of Bromine= 159.8 g/mol
Molecular Weight of Aluminum Bromide= 266.7 g/mol
So,
Moles of Br = 6 moles
Moles of Al = = 4moles
similarly,
moles of = = 1mole
Moles of =
1 mole =
weight = 2.67×g

I’m pretty sure the answer is
↳ To transport materials throughout the body!
Multicellular organisms need a circulatory system to transport substances to and from their cells!
There you go! I hope this helped, if there’s anything just let me know! ☻
Answer:
It is stable because it's electrically neutral
It's 1 electron and 1 proton
Answer:The atomic mass of the second isotope of an element X 17 amu with atomic number of 7 and it is represented by X-17.
Explanation:
Number of protons in isotope X-15,(p) = 7
Number of neutrons in isotope X-15,(n) = 8
Atomic mass of the isotope X-15 = (p) + (n) = 7 + 8 = 15 amu
Number of protons in second isotope of an element X,(p) = 7
Atomic number = Number of protons in an atom of an element
Number of protons in the isotopes of same element remains the same
Number of neutrons in second isotope of an element X,(n) = 10
Atomic mass of the second isotope of an element X= (p) + (n) = 7 + 10= 17 amu
The atomic mass of the second isotope of an element X 17 amu with atomic number of 7 and it is represented by X-17.
