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.
Answer:
Beginning from the innermost layer and moving towards the outermost of the sun that has six layers.
1. Innermost layer is the core: All the energy of the sun comes from core. Here hydrogen and helium are components that are present.
2. Radiative zone: The high-energy photons are move from the innermost core to the second innermost radiative zone.
3. Convective zone: It is a comparatively cooler layer to the core and radiative zone.
4. Photosphere: It is the 4th innermost region with sunspots and called the magnetic field of the sun.
5. Chromosphere: This red color layer with filaments of gas is cooler than the photosphere.
6. Corona: It is the outermost layer of the sun and the temperature is much higher here.
Answer:
The specific heat (\(c_s\)) of a substance is the amount of energy needed to raise the temperature of 1 g of the substance by 1°C, and the molar heat capacity (\(c_p\)) is the amount of energy needed to raise the temperature of 1 mol of a substance by 1°C. Liquid water has one of the highest specific heats known.
Explanation:
Based on the concentrations given, the volume of vinegar required is 5.04 mL.
<h3>What is the concentration of the vinegar solution?</h3>
The concentration of a solution is the amount of solute in a given volume of solution.
Concentration can be expressed as:
- molar concentration
- percentage concentration
The concentration of the vinegar solution is 4.76% (w/w). This means that 4.76 g of vinegar is present in 100 g of solution.
Mass of vinegar = 4.76 g
molar mass if vinegar = 60 g/mol
moles of vinegar = 4.76/60 = 0.0793 moles
volume of solution/water = 100 mL or 0.1 L
Molarity of vinegar = 0.0793/0.1 = 0.793 M
1 mole of vinegar reacts with 1 mole of NaOH
let the volume of vinegar required be V
0.793 M × V = 40 × 0.1
V = 4/0.793
V = 5.04 mL
Therefore, the volume of vinegar require is 5.04 mL.
