Answer:
<u>Heating water with an open flame</u>
<u>Explanation:</u>
Remember, we are told in the label that Acetone is a "flammable liquid and vapor." <em>Being flammable means the substance can easily be set on fire</em>, and we would expect an open flame from heating water to trigger an explosion (a disaster) in which the Acetone is set on fire causing life-threatening dangers to the second group of students.
In a redox reaction electrons are lost and gained in equal numbers. The species that is oxidized gives electrons to the species that is reduced. I hope this helps. Let me know if anything is unclear.
<span>Liquid alcohol will change to vapor when temperature reaches the : D. Boiling point
When the temperature reach the boiling point, the molecule that held the liquid's particle together will break free and the particle will scatter.
This will cause the liquid substance to undergone a transformation into a Gaseous form</span>
Answer: Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction.
Explanation:
Dalton's Atomic Theory was proposed in the 20th century by an English Scientist named John Dalton. His theory is postulated as follows:
1) All elements are composed of tiny indivisible particles called atoms.
2) The atoms of any one element are identical to those of any other element. 3) Atoms of different elements can physically mix together or can chemically combine in simple whole-number ratios to form compounds.
However, the final option is NOT one of Dalton's Theory
Chlorine-36 has been widely used for dating old groundwater.
