In the reaction 2hgo(s) --> 2hg(l) + o2(g) we measure the evolution of gas to determine the rate of reaction. at the beginning of the reaction (at 0 minutes), 0.02 l of o2 is present. after 10 minutes the volume of o2 is 0.36 l. what is the rate of reaction? question 4 options:

0.034 L/min

Step-by-step explanation:

The rate of reaction is the volume change (ΔV) divided by the time(t) and divided by the coefficient of the compound in the reaction. The coefficient of O₂ is 1, so:

R = (0.36 - 0.02)/10

R = 0.034 L/min

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
