Explanation:
moles = mass/mr
=60.3/28
=2.15 moles
number of particles = moles × 6.02×10^23
= 2.15×6.02×10^23
= 1.29×10^24 atoms
CO=12+16=28
Seasickness. The symptoms of carbon monoxide poisoning mimic the symptoms of seasickness.
Answer: There are 5.99 moles present in atoms of Carbon.
Explanation:
According to the mole concept, 1 mole of every substance contains atoms.
Therefore, number of moles present in atoms are as follows.
Thus, we can conclude that there are 5.99 moles present in atoms of Carbon.

3. F
Explanation:
<em>Determine if the following statements are true or false. </em>
- <em>The rate law for an overall reaction can be written using the coefficients from the overall reaction.</em> FALSE. The rate law includes the reaction orders, which have to be determined experimentally and may or may not be equal to the coefficients of the overall reaction.
- <em>The rate-determining step of the reaction is always the first step of the reaction.</em> FALSE. The rate-determining step is always the slowest step.
- <em>A catalyst is a species that is added to the reaction, lowers the activation energy of a reaction, shows up in the rate law (most of the time), and will be in the overall balanced equation.</em> FALSE. A catalyst does lower the activation energy of the reaction, but it doesn't show up in the rate law nor the overall balanced equation.
