Answer:

47.1 L.

Explanation:

  • To solve these problems, we can use the general law of ideal gas: <em>PV = nRT.</em>

where, P is the pressure of the gas in atm (P = 234.0 kPa/101.325 ≅ 2.31 atm)  .

V is the volume of the gas in L (V = ??? L).

n is the no. of moles of the gas in mol (n = 3.9 mol).

R is the general gas constant (R = 0.082 L.atm/mol.K),

T is the temperature of the gas in K (T = 67.0 °C + 273.15 = 340.15 K).

The volume of the gas = nRT/P.

<em>∴ V = nRT/P </em>= (3.9 mol)(0.082 L.atm/mol.K)(340.15 K)/(2.31 atm) = <em>47.1 L.</em>

Consider the reaction below. If the concentration of B decreases by 0.068 M, what will be the change in concentration for C? 3A(
SOVA2 [1]

Answer:

.085 M .

Explanation:

  3A(g)   +4B(g)  ⇋  5C(g)

4 moles of B reacts with A to form 5 moles of C

.068 moles of B will reacts with A to form  5 x .068 / 4 moles of C

Moles of C formed

= 5 x .068 / 4

= .085 moles .

There are 4 molecules racing to get across a typical cell membrane. Contestants: a.C6H12O6, b.CO2, c.Cl- and d.CH3CH2CH2COOH (a
dmitriy555 [2]

Answer:

b.CO2

d.CH3CH2CH2COOH (a fatty acid)  

c.Cl-

a.C6H12O6

Explanation:

The cell membrane is permeable to gases and fatty acids, as they are non polar and small molecules. Those goes throught the cell membrane with no need of a canal or carrier.

The polar and big molecules needs a canal (as Cl-) or carrier (as C6H12O6) to get the cytoplasma.
