B. kilometers
C. millimeters
D. centimeters
Answer:
The answer is C
Explanation:
Precision generally means been accurate (and can be loosely interpreted to mean been exact). Length is averagely measured in meters. However, in order to get the actual length of a substance using a tape, millimeters give the most accurate length (of all the options) as it provides the length to the smallest details (of all the options provided). The illustration below shows the relationship between millimeters and the rest of the options.
while 1 kilometer = 1000 meters
1 meter = 100 centimeters
1 centimeter = 10 millimeters
From the relationship above, millimeters is clearly the most precise of all the options provided.

Answer:
The percent yield of reaction is 54.32%.
Explanation:
Moles of methane =
According to reaction, 1 mole of methane gives 2 moles of water .
The 0.3115 moles of methane will give:
of water
Mass of 0.9345 moles of water = 0.623 mol × 18.02 g/mol = 11.23 g.
Theoretical yield of methane = 11.23 g.
Experimental yield of methane = 6.10 g.
The percent yield of reaction:
The percent yield of reaction is :
