The statement above is TRUE.
The statement that is given above implies that, if a paint sample matches another known sample from a vehicle, that does not indicate that the paints come from the same source but it does show a very high probability that the paint samples come from the same object, if the compositions of the paint samples are the same.
Answer:
B. The electronegativities of the two atoms are equal.
Answer:
Okay, Left top= waning gibbous
left second= new moon
left third= third quarter
left fourth= waxing crescent
right top= Waning crescent
right second= first quarter
right third= full moon
right fourth= Waxing gibbous
hope you do good :)
I think the symbol of the element is Ga sorry if I’m wrong
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.
