Answer:
two atoms
Explanation:
In its stable molecular form, oxygen exists as two atoms and is written O2. to distinguish it from an atom of oxygen O, or ozone, a molecule of three oxygen atoms, O3. Even though each of these is all oxygen, combining atoms of the same element may give very different properties to the molecule.
Answer:
2. An object that transfers heat well
Explanation:
Conductors has closer molecules in which can bump into each other easily to help transfer thermal energy. Examples are iron, steel, gold, copper, and other metals.
1.) Gas given off
2.) precipitate formed
3.) large amount of heat given off
4.) Color change
Answer:
The reaction rate is inversely proportional to the reaction time.
Explanation:
- The reaction rate is the change of the concentration of reactants and products with the time.
<em>∵ Reaction rate = - Δ[reactants]/Δt = Δ[products]/Δt.</em>
<em>∴ The reaction rate is inversely proportional to the time, as the reaction rate increases it will take a lower time.</em>
