Apiece of dry ice (solid carbon dioxide) with a mass of 5.50 g is placed in a 10.0-l vessel that already contains air at 705 torr and 24 °c. after the carbon dioxide has totally sublimed, what is the partial pressure of the resultant co2 gas, and the total pressure in the container at 24 °c?

 The partial  pressure  of  resultant CO₂  gas  is 231.5 torr

The total  pressure = 936.5 torr

 calculation

The partial  for CO₂  is calculated using  the ideal gas equation

That is PV=nRT

where;

p(pressure = ?

V( volume) = 10.0 l

n(number of moles) = mass÷molar mass

from periodic table the molar mass of CO₂ = 12 + (16 x2)  = 44 g/mol

moles = 5.50 g÷44 g/mol =0.125 moles

R( gas constant) = 62.36 torr

T ( temperature) = 24°c into Kelvin = 24 +273 =297 K

make P the subject  of the formula by diving both side of equation by V

P  =nRT/V

P  ={( 0.125 moles x 62.36 L.torr/Mol.K  x297 K)  / 10 L}  = 231.5 torr

Total pressure = partial pressure for air + partial  pressure for CO₂

= 705 torr + 231.5 torr =936.5 torr

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
