Answer:
<em>Well, Your best answer will be is 2H+ + 2OH- -> 2H2O but you have to reduce it to H+ + OH- -> H2O. </em><em>Good Luck!</em>
Answer:C
Explanation: The mass is still the same even though they took it apart.
<span>The
answer is compound. Elements are
composed of one kind of atoms bonded
together. There are different types of compounds: ionic, complexes, molecular,
and intermetallic compounds. The proportion of
elements in the compound is expressed
using a chemical formula. An example of
an element is Aluminium while an example of a compound is H2S (Hydrogen sulfide).</span>
2 m/s
Explanation:
The distance to school is 14.4 kilometers which are equal to 14400 meters.
Amy takes 40 minutes which are equal to 40 × 60 = 2400 seconds to arrive at school.
Bill takes 40 + 20 = 60 minutes which are equal to 60 × 60 = 3600 seconds to arrive at school.
Amy’s average speed = distance (m) / time (s)
Amy’s average speed = 14400 m / 2400 s = 6 m/s
Bill’s average speed = 14400 m / 3600 s = 4 m/s
How much faster (in meters/second) is Amy’s average speed for the entire trip?
Amy’s average speed - Bill’s average speed = 6 m/s - 4 m/s = 2 m/s
