Answer:
Q < K for both reactions. Both are spontaneous at those concentrations of substrate and product.
Explanation:
Hello,
In this case, the undergoing chemical reactions with their proper Gibbs free energy of reaction are:
The cellular concentrations are as follows: [A] = 0.050 mM, [B] = 4.0 mM, [C] = 0.060 mM and [D] = 0.010 mM.
For each case, the reaction quotient is:
A typical temperature at a cell is about 30°C, in such a way, the equilibrium constants are:
Therefore, Q < K for both reactions. Both are spontaneous at those concentrations of substrate and product.
Best regards.
<span>From the Born–Landé equation the lattice energy U ∝ (Z+ × Z-) / (r+ + r-) where Z+ and Z- are the charges on the cation and anion, respectively; r+ and r- are radii of the cation and anion, respectively.
The Z+×Z- term dominates. MgO has 2×2 (4) so it will have the higher U than Li2O Z+ × Z- = 2.
You only consider (r+ + r-) term when the Z+×Z- term is the same; smallest the (r+ + r-), the larger is the U.
U(MgO) = 3795 </span>kJ mol^-1
<span>U(Li2O) = 2799 kJ mol^-1
MgO has larger.

Answer:
meander
Explanation:
A meander is the the “winding” shape that a river can take. It is is one of a series of regular sinuous curves, bends, loops, turns, or windings in the channel of a river, stream, or other watercourse(wikipedia).
A meander is formed when water in the river erodes the banks just outside its channel. The water then deposits some sediments inside the channel.
Answer:
false
in chemical reaction element doesnot change into another
Explanation:
Answer:
All bases conduct electricity as they are good electrolytes. All bases turn red litmus paper into blue at the time of indication. Bases have a bitter taste with a soapy texture
