A 8.65-L container holds a mixture of two gases at 11 °C. The partial pressures of gas A and gas B, respectively, are 0.205 atm
Vsevolod [243]

 The  total pressure  = 1.402 atm


<u><em>calculation</em></u>

Total  pressure = partial  pressure  of gas A + partial pressure of gas B +  partial pressure  of third gas

partial  pressure  of gas A= 0.205 atm

Partial pressure of gas B =0.658 atm


partial pressure for third gas is calculated using ideal  gas equation

that is PV=nRT   where,

p(pressure)=? atm

V(volume) = 8.65 L

n(moles)= 0.200 moles

R(gas constant)=0.0821 L.atm/mol.k

T(temperature) = 11°c into kelvin =11+273 =284 k

make  p the subject of the formula by  diving both side by V

p =nRT/v


p = [(0.200 moles x 0.0821 L.atm/mol.K x 284 K)/8.65L)] =0.539 atm



Total  pressure  is therefore = 0.205 atm +0.658 atm +0.539 atm

=1.402 atm

When a compound is dissolved in hot ethanol during a recrystallization, what is changing on a molecular level? The intermolecula
Feliz [49]

Answer:

The intermolecular forces between the solute and solvent.

Explanation:

When you are heating a solvent, the intermolecular forces are reduced because the distances between molecules are large. Thus, in a solution where solvent is hot the intermolecular forces between solute and solvent are lower than those solutions where solvent is in room temperature.

The covalent bonds do not change because this mean a chemical reaction that doesn't occur in a solution.

Usually solid solutes melts in a higher temperature than boiling point in solvents. Thus, a compound normally doesn't melt in a hot solvent.

I hope it helps!

If an atom of Bromine (Br) becomes an ion, which of the following does it most likely form?
lawyer [7]

Answer:

An atom of Bromine (Br) forms an ion and becomes Br⁻

Explanation:

  • Atoms of elements gain or lose electron(s) to attain a stable configuration and form ions.
  • When an atom gains electron(s) it forms a negatively charged ion called an anion.
  • For example, Bromine is a halogen and its atom requires to gain one electron to attain stability and form a bromine ion (Br⁻).
  • When an atom loses electron(s) it forms a positively charged ion called a cation.
  • For instance, atoms of calcium(Ca) requires to lose two electrons to attain stability and form calcium ion (Ca²⁺).

3) What is the mass of a sample consisting of 1.00 X 1022 formula units of MgSO.?(​
Montano1993 [528]

number of moles = 1.00 X 10^22 ÷ 6.022 × 10^23

= 0.0166 moles

mass = number of moles × molar mass

= 0.0166 × 120.37 = 2.00 g
