C₂H₃O₂⁻ is an anion.
<u>Explanation:</u>
NaC₂H₃O₂(s) → Na⁺(aq) + C₂H₃O₂⁻(aq)
NaC₂H₃O₂ when dissociated, yields Na⁺ and C₂H₃O₂⁻.
Anion is a negatively charged ion.
In this case, C₂H₃O₂⁻ is an anion.
Answer:
2 Newtons
Explanation:

Therefore, your mass would be 1kg and your acceleration would be 2m/s/s
Plug the numbers into the equation:

which will equal

An object with more mass has more kinetic energy than an object with less mass, if both objects are moving at the same speed. <em>(c)</em>
P = m*v
7.5 = m*15
m = 7.5/15 = 0.5 kg
