I believe the answer is is that his machine must increase the distance the object moves.
Answer:
There are 1.205x10²³ particles in 0.2 moles.
Explanation:
In order to <u>convert from moles to number of particles</u> we need to use <em>Avogadro's number</em>, which states the number of particles contained in 1 mol:
- 0.2 mol * 6.023x10²³ particles /mol = 1.205x10²³ particles
Thus, there are 1.205x10²³ particles in 0.2 moles.
Answer:
The website is inaccurate.
Explanation:
Remember, a chemical change is characterized by many things, but most commonly:
- A change in color, temperature or state.
- An irreversible change
- One or more new substances are formed
Rusting (Iron oxide) is a redox reaction (Oxidation-Reduction Reaction) where iron molecules come in contact with water and oxygen molecules. The iron molecules lose electrons, becoming oxidized, while oxygen gains electrons, becoming reduced.
Is rust reversable? (No)
Did the colour of the iron on the surface change? (Yes)
Did a new substance form? (Yes, Read above).
Hope I helped! Have a good day!
Answer:
Fish need to be aerodynamic to move quickly. If they had legs they woulf be less aerodynamic and unable to get away from predators.
The statement that best describes the effect of low ionization energies and low electronegativities on metallic bonding is the first one - the valence electrons are easily delocalized.
Due to these low energies and negativities, valence electrons can be moved around quite easily and their positions may be altered quite drastically.
