Select the appropriate coefficient for O2 when the equation ? O2(g) + ? C5H12(g) → ? CO2(g) + ? H2O(g) is balanced using the sma

Kisachek [45]

Answer:

4O₂ (g) + 1/2C₅H₁₂ (g) → 5/2CO₂ (g) + 3H₂O (g)

4 would be the smallest possible integer for O₂

Explanation:

The balanced equation is this one:

8O₂ (g) + C₅H₁₂ (g) → 5CO₂ (g) + 6H₂O (g)

If we divide stoichiometry /2 (the half) we can consider that we use, the smallest possible integers.

8/2O₂ (g) + 1/2C₅H₁₂ (g) → 5/2CO₂ (g) + 6/2H₂O (g)

4O₂ (g) + 1/2C₅H₁₂ (g) → 5/2CO₂ (g) + 3H₂O (g)

Predict (to 3 sig figs) the isochoric specific heat of gaseous SF6 (molar mass 146.06 g/mol) at 1200 K, assuming that at this te

bazaltina [42]

Explanation:

As it is known that $SF_{6}$ molecule is a non-linear molecule. Therefore, its isochoric heat capacity will be as follows.

$C_{v} = \frac{3}{2}R + \frac{3}{2}R + (3 \times 7 - 6)R$

= $\frac{3}{2}R + \frac{3}{2}R + 15R$

= 18 R

Also, $C_{V} = M \times C_{v}$

where, $C_{V}$ = molar heat capacity

M = molecular mass

$C_{v}$ = specific heat

Hence, calculate the value of $C_{v}$ as follows.

$C_{V} = M \times C_{v}$

$8 \times 8.314 \times 10^{7} = 146.06 \times C_{v}$

$C_{v} = 10.2 \times 10^{6} erg. K^{-1}. gm^{-1}$

This means that value of isochoric specific heat is $10.2 \times 10^{6} erg. K^{-1}. gm^{-1}$ .

Yes, we have to assume ideal gas behavior because for ideal gas:

dU = $nC_{v}dT$

Whereas for real gases " $\frac{an^{2}}{V^{2}}$ " has to be added here.

Researchers can use solvents to extract, or break apart, components of a cell or tissue to separate and/or isolate components. I

Tems11 [23]

The cell membrane which is more fat permeable will be present at the end of the process.

Solvent extraction is a very important method if separating mixtures. The principle of solvent extraction is based on the idea of like dissolves like. A substance dissolves in the component of the system in which it is most soluble.

If a cell extract is dissolved in a nonpolar solvent, the cell membrane which is mostly permeable to nonpolar molecules will dissolve most in the solvent.
