Explanation:

Carbohydrates covalently linked to proteins (glycoproteins) or lipids (glycolipids) are also a part of cell membranes, and function as adhesion and address loci for cells. The Fluid Mosaic Model describes membranes as a fluid lipid bilayer with floating proteins and carbohydrates.

In nature, one common strategy to make thermodynamically unfavorable reactions proceed is to couple them chemically to reactions

padilas [110]

Answer:

$\triangle G= -6.7 KJ/mol$

Explanation:

From the question we are told that:

Chemical Reactions:

X=A⇌B,ΔG= 14.8 kJ/mol

Y=B⇌C,ΔG= -29.7 kJ/mol

Z=C⇌D,ΔG= 8.10 kJ/mol

Since

Hess Law

The law states that the total enthalpy change during the complete course of a chemical reaction is independent of the number of steps taken.

Therefore

Generally the equation for the Reaction is mathematically given by

$T = +1 * X +1 * Y +1 *Z$

Therefore the free energy, ΔG is

$\triangle G=1 * \triangle G*X +1 * \triangle G*Y +1 * \triangle G *Z$

$\triangle G= +1 * (14.9) +1 * (-29.7) +1 * (8.10)$

$\triangle G= -6.7 KJ/mol$

1.2 L sample of gas is determined to contain 0.5 moles of nitrogen. At the same temperature and pressure, how many moles of gas

hram777 [196]

A 20 L sample of the gas contains 8.3 mol N₂.

According to Avogadro’s Law, if p and T are constant

V₂/V₁ = n₂/n₁

n₂ = n₁ × V₂/V₁

___________

n₁ = 0.5 mol; V₁ = 1.2 L

n₂ = ?; V₂ = 20 L

∴n₂ = 0.5 mol × (20 L/1.2 L) = 8.3 mol

2) Which liberates the most energy?

evablogger [386]

Answer: $F(g)+e^-\rightarrow F^-(g)$

Explanation:

Electron gain enthalpy is defined as energy released on addition of electron to an isolated gaseous atom.

The amount of energy released will be maximum when the tendency to attract electrons is maximum. As flourine has atomic number of 9 and has electronic configuration of 2,7. It can readily gain 1 electron to attain stable noble gas configuration and hence liberates maximum energy.

$F(g)+e^-\rightarrow F^-(g)$
