gregori [183]

Answer:

n= 0.08186

{He}2s^2 2p^6

Explanation:

PV=nRT

n=PV/RT

n= (1.220 atm)(4.3410 L) / (0.0821 atm*L/mol*K)(788.0 K)

n=0.08186

As for the electron configuration:

Ne:

{He} 2s^2 2p^6

or long hang:

1s^2 2s^2 2p^6

Which of the following is not equal to 0.1 centimeters?
Anon25 [30]

Answer:

c) 10 millimeters (mm)

Explanation:

The unit conversions are as follows:

1 cm = 10 mm (millimeter)

1 cm = 0.01 m (meter)

1 cm = 0.00001 km (kilometer)

1 cm = 10000 μm (micrometer)

Based on the above conversions:

0.1 cm = \frac{10 mm*0.1 cm}{1 cm} = 0.1 mm

0.1 cm = \frac{0.01 m*0.1 cm}{1 cm} = 0.001 m

0.1 cm = \frac{0.00001 km * 0.1 cm}{1 cm} = 0.000001 km

0.1 cm = \frac{10000 um*0.1cm}{1 cm} =1000 um

Therefore, 0.1 cm = 10 mm is incorrect instead it is 0.1 mm
