Answer:
Look on the picture.
Explanation:
He could find only 2 isomers of n-hexane alkenes for this reaction. Other two could be marked from other direction.
Answer:
air is not a mixture because of scientists freezing it and finding different liquids, it is a mixture because the compounds that make up air e.g. oxygen (o2), Carbon dioxide (co2) and the most important Nitrogen which is an element and makes up 78.09% of air are not chemically bound in the way that compounds are
Explanation:
The volume in liters of 576 grams of SO2 gas at STP is calculated as below
calculate the moles of SO2 = mass/molar mass
= 576 g/64 g /mol = 9 moles
At STP 1mole =22.4 L
what 9 mole =? liters
by cross multiplication
= 22.4 L x 9 moles/ 1moles = 201.6 liters
Answer:
Balanced chemical equation:
2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
Explanation:
Chemical equation:
Al + H₂SO₄ → Al₂(SO₄)₃ + H₂
Balanced chemical equation:
2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
Steps:
Let balance the SO₄ first.
Al + 3H₂SO₄ → Al₂(SO₄)₃ + H₂
There are three H₂ on left so put the coefficient three on right too.
Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
Two Al on right and one on left so we will put the coefficient two on left.
2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
All atoms are correctly balanced.
