Answer:

P_A=4.20atm\\\\P_B=17.1atm

Explanation:

Hello!

In this case, since the equation for the ideal gas is:

PV=nRT

For each gas, given the total volume, temperature (28.1+273.15=301.25K) and moles, we can easily compute the partial pressure as shown below:

P_A=\frac{n_ART}{V} =\frac{1.21mol*0.082\frac{atm*L}{mol*K}*301.25K}{7.12L} \\\\P_A=4.20atm\\\\P_B=\frac{n_BRT}{V} =\frac{4.94mol*0.082\frac{atm*L}{mol*K}*301.25K}{7.12L} \\\\P_B=17.1atm

Best regards!

Answer:

In the given figure, There are two atoms -

  • Sodium ( Na )
  • Chlorine ( Cl )

sodium has one electron in valence shell and to get noble gas configuration ( stability ) it need to donate the outer most electron.

whereas,

chlorine has 7 electrons in valence shell and to get noble gas configuration ( stability ) it need to get one more electron.

in this condition Na ( sodium ) donates it's outermost electron to Cl ( chlorine ) and both became stable.

but now sodium has more number of protons than the electrons hence it get positive (+) charge and chlorine has more electrons than the protons hence it get negative (-) charge

so, they get stick to each other by strong electrostatic force acting on the charged atoms and forms a salt " NaCl " ( sodium chloride ) .

What is the angle between the carbon-sulfur bonds in the carbon disulfide ( cs2 ) molecule?
Bingel [31]

Answer:

180º

Explanation:

Carbon has 4 valence electrons and to complete the octet requires 4 more , so it will share with the oxigen atoms 4 more, forming a single and a pi bond similar to CO2

Since the carbon does not have lone pairs, the geometry around this central atom will be linear and the angle will be 180 ,   S = C = S
