Answer:
It's false.
Explanation:
Molecular orbital theory states that the number of molecular orbitals is equal to the number of atomic orbitals that overlap. The lowest energy molecular orbital is formed when two atomic orbitals that are in phase overlap, forming a bonding molecular orbital. However, another molecular orbital is also formed, called an anti-binding orbital.
So if an "n" quantity of atomic orbitals is combined, an "n" quantity of molecular orbitals is formed.
Have a nice day!
Answer:
c. 30mL
Explanation:
NaOH + HCl ---> H2O + NaCl
conc. = mol/vol
mol HCl = conc. x vol
= 1.0 x 30
= 30mol
mol NaOH = 30mol
vol. = mol/conc
= 30/1.0
= 30mL
I would get a container and weigh it. Then I would put the bouncy balls in the container and weigh it again. Then I would Subtract the weight of the container without the bouncy balls from the container with the bouncy balls.
Answer:
There are 8.55ₓ10²⁵ atoms of P, in 7.1 moles of Cu₃(PO₄)₂
Explanation:
Copper (II) ⇒ Cu²⁺
PO₄⁻³ → phosphate
3Cu²⁺ + 2PO₄⁻³ → Cu₃(PO₄)₂
1 mol of copper (II) phosphate has 2 mol of P, 8 moles of O and 3 moles of Cu.
Then, 7.10 moles of salt has (7.1 .2) = 14.2 moles of P
In 1 mol we find, NA atoms (6.02ₓ10²³)
In 14.2 moles we would find (14.2 .NA) = 8.55ₓ10²⁵ atoms
