When Na forms an ion it loses its outer electron to become Na+. Write the electron configuration for Na and Na+. What element do
Otrada [13]

Answer:

Na: 1s2 2s2 2p6 3s1

Na+: 1s2 2s2 2p6

Na+ electronic configuration resemble that of Neon( 1s2 2s2 2p6)

In general, the electronic configuration of alkali metals ions resemble that of the group zero (noble gas)

Determine the change in entropy for 2.7 moles of an ideal gas originally placed in a container with a volume of 4.0 L when the c
olchik [2.2K]

Answer:

The value of entropy change for the process dS = 0.009 \frac{KJ}{K}

Explanation:

Mass of the ideal gas = 0.0027 kilo mol

Initial volume V_{1} = 4 L

Final volume V_{2} = 6 L

Gas constant for this ideal gas ( R ) = R_{u}  M

Where R_{u} = Universal gas constant = 8.314 \frac{KJ}{Kmol K}

⇒ Gas constant R = 8.314 × 0.0027 = 0.0224 \frac{KJ}{K}

Entropy change at constant temperature is given by,

dS = R  log _{e} \frac{V_{2}}{V_{1}}

Put all the values in above formula we get,

dS = 0.0224  log _{e} [\frac{6}{4}]

dS = 0.009 \frac{KJ}{K}

This is the value of entropy change for the process.

How many moles of NO2 form when<br> 63.25 g N2O5 decompose?<br><br> 2N₂O54NO₂ + O₂
KonstantinChe [14]

Answer:

1.1713 moles

Explanation:

RFM of N2O5=108

Moles of N2O5= mass/RFM= 63.25/108=0.5856 moles

Mole ratio of N2O5:NO2= 2:4

Therefore moles of NO2= 4/2*0.5856= 1.1713 moles
