These glasswares can be ranked from the least accurate (1) to the most accurate (3) as follows;

Beaker - 1

Graduated cylinder - 2

Volumetric pipette - 3

The beakers are considered to be the least accurate since they are in graduations of 25 or 50 ml. They are also not calibrated during manufacturing.

Graduated cylinders are more precise than beakers since they have permanently marked incremental graduations incorporated in the cylinder hence making them more accurate at reading the volumes of the inside liquids.

Volumetric pipettes are the most accurate as compared to the other two given glassware as they allow the measurement to four significant figures and have an error of a few hundredths of a milliliter.

How many moles of a gas sample are in a 5.0 L container at 205 K and 340 kPa?
Mazyrski [523]

Answer:

1.0 mole

Explanation:

From the question given above, the following data were obtained:

Volume (V) = 5 L

Temperature (T) = 205 K

Pressure (P) = 340 KPa

Gas constant (R) = 8.31 KPa.L/Kmol

Number of mole (n) =?

Using the ideal gas equation, the number of mole of the gas in the container can be obtained as follow:

PV = nRT

340 × 5 = n × 8.31 × 205

1700 = n × 1703.55

Divide both side by 1703.55

n = 1700 / 1703.55

n = 1.0 mole

Thus, the number of mole of the gas in the container is 1.0 mole

Which equation represents an addition reaction?
jeka57 [31]

c3h6 + cl2---- c3h6cl2 is a type of  equation represents an addition reaction because new products are formed.

<h3>What is addition reaction?</h3>

Addition reaction is a type of reaction in which one molecule combines with another to form a bigger molecule having no other products. We can see that the above reaction has no byproduct.

So we can conclude that c3h6 + cl2---- c3h6cl2 is a type of  equation represents an addition reaction because new products are formed.
