The reaction rate is the speed at which products form, based on the rate of the slowest step in the mechanism.
Answer:
The frequency of wave is 0.125 Hz.
Explanation:
Frequency:
"It is an event repeat itself in a given period of time"
The unit of frequency is the Hz . If time is measured in seconds then frequency will be in Hz. Hz is equal to the per second.
Formula:
f = 1/ T
f = 1/ 8 sec
f = 0.125 Hz

Answer:
The mass of 3.491 × 10¹⁹ molecules of Cl₂ of Cl₂ is 4.11 × 10⁻³ grams
Explanation:
The number of particles in one mole of a substance id=s given by the Avogadro's number which is approximately 6.023 × 10²³ particles
Therefore, we have;
One mole of Cl₂ gas, which is a compound, contains 6.023 × 10²³ individual molecules of Cl₂
3.491 × 10¹⁹ molecules of Cl₂ is equivalent to (3.491 × 10¹⁹)/(6.023 × 10²³) = 5.796 × 10⁻⁵ moles of Cl₂
The mass of one mole of Cl₂ = 70.906 g/mol
The mass of 5.796 × 10⁻⁵ moles of Cl₂ = 70.906 × 5.796 × 10^(-5) = 4.11 × 10⁻³ grams
Therefore;
The mass of 3.491 × 10¹⁹ molecules of Cl₂ of Cl₂ = 4.11 × 10⁻³ grams.
