<span>The statement is false. It was Democritus, a Greek
philosopher, who first theorized that matter was ultimately composed of atoms.
His ideas were not widely accepted in his time (460-370 B.C), but during the 19th
century, John Dalton proposed this theory and gained broad acceptance.</span>
The answer is: True
I took the quiz and it was correct
Answer:
8 moles SO₂
Explanation:
To find the moles SO₂, you need to multiply the given value by the mole-to-mole ratio. This ratio, between O₂ and SO₂, is made up of the coefficients from the balanced equation.
2 H₂S + 3 O₂ -----> 2 SO₂ + 2 H₂O
12 moles O₂ 2 moles SO₂
-------------------- x ---------------------- = 8 moles SO₂
3 moles O₂
1: if the solid is heating and is not yet to the melting point, the answer would be "solid". If the substance reached the melting point and is heating up at that point, the answer would be "solid and liquid" (yes, at the same time).
2. boiling point.
Once the substance is melted completely into a liquid, the highest point where the substance will still exist as a liquid would be the boiling point.
3. gas.
The three main states of matter from cooler to hotter are:
solid, liquid, and gas.
