pishuonlain [190]

<span>The answer is No, it is not possible that the reverse reaction will occur at ordinary conditions. This is because the entropy of the KCl and the O2 are much largely negative than that of the KClO3. The entropy component of the Gibbs free energy assures that the Gibbs free energy for the reverse reaction is positive (Positive Gibbs means nonspontaneous reaction). </span>

What is 3.35 x 10^14 Hz?
Andrews [41]

Answer:

335,000,000,000,000 Hz

Explanation:

3.35 x 10^14 is just scientific notation. This is a way to make a really big number small to write and easier to understand. The exponent on the 10 represents how many times you move the decimal to the right. If the exponent is negative you should move the decimal to the left. Each time the decimal is moved, and there is no pre-existing number, you need to add a zero.

3.35 x 10^14 is equal to

335,000,000,000,000
