Petroleum is used as a fuel to power vehicles and machines.
Petroleum products include fuel oils for heating and electricity generation.
It is a feedstocks for making the chemicals and plastics.
We use petroleum to produce electricity.
Explanation:
The atomic spectrum is more like the transitions of electrons among electronic energy levels in an isolated atom. Atomic spectrum is mainly affected by interaction of the transitioning electrons between the nuclei spins and between the other electrons in the same atom.
However, molecular spectrum involve transition of electrons in molecules with two and more atoms(it can be in the same or different). Also, the valence electrons are now in different orbitals than that of the atomic orbitals and the orbital structure has changed the electronic transitions are different
Answer:
7.82 g of Cu
Explanation:
2 moles of Al react to 3 moles of copper sulfate in order to produce 3 moles of copper and 1 mol of aluminum sulfate.
Firstly we determine the moles of reactant.
As copper sulfate is in excess, Al is the limiting.
2.75 g . 1mol /26.98g = 0.102 moles
Ratio is 2:3. 2 moles of Al, can produce 3 moles of Cu
So the 0.102 moles of Al will produce(0.102 . 3) /2 = 0.153 moles.
We convert moles to mass: 0.153 mol . 63.5g /mol = 9.71 g
That's the theoretical yield (100 % yield reaction)
We know that: (yield produced / theoretical yield) . 100 = percent yield
We replace:
(Yield produced / 9.71g) . 100 = 80.5 %
(Yield produced / 9.71g) = 0.805
Yield produced = 0.805 . 9.71g = 7.82 g
Answer:
C; Corrosive
Explanation:
Corrosive is related to the word “Corroded”
Ever heard of when batteries get corroded? That’s when they get old so the acid leaks and damages the actual battery. Same thing. So the answer is C.
I hope this helps! :D
Pls give thx and brainliest if I’m right ;)
The answer is A- single bonds made by 1 atom to 3 other atoms within a molecule
