Answer:
Visible light
Explanation:
our eyes are sensitive to a very narrow band of frequencies within the enormous range of frequencies of the electromagnetic spectrum. This narrow band of frequencies is referred to as the visible light spectrum. Visible light.
Answer:
its polar end mixes with the water so it can be washed away
Explanation:
just did the tests
a p e x
I believe so because the oxygen goes from 0 to 2- and magnesium goes to 2+ so the oxygen is being reduced and the magnesium is begin oxidized.
1 mol Au ---------------- 196.9665 g
0.150 mol Au ----------- ?
0.150 x 196.9665 / 1
= 29.54 g
hope this helps!
Answer:
coefficient 3 is needed t with water molecule to balance the equation.
Explanation:
Chemical equation:
Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O
Balanced chemical equation:
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
The equation is balanced. There are two iron three sulfate six hydrogen and three oxygen atoms are present on both side of equation.
The given equation completely follow the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Coefficient with reactant and product:
Fe₂O₃ 1
H₂SO₄ 3
Fe₂(SO₄)₃ 1
H₂O 3
So coefficient 3 is needed t with water molecule to balance the equation.
