Answer:
8.34 moles
Explanation:
We are given 8.34 moles.
We need to find moles: 8.34
Answer:
The biological significance is that it is the normal human body temperature and also the optimum temperature of the enzyme.
Explanation:
- Enzymes are biological catalysts that speed up the rate of chemical reactions.
- Enzymes catalyze specific reactions by working on a specific substrate to convert it into a product.
- The rate of enzyme activity depends on several factors which include pH, temperature, substrate concentration, and enzyme concentration among others.
- Enzymes work best at a specific pH and temperature known as optimum pH and optimum temperature respectively.
- In this case, enzyme amylase works best at a temperature of 37° C which is equivalent to the normal human body temperature.
Weather radar consists of a rotating dish protected by a large white dome; this dish sends pulses of energy (the radar beam) into the atmosphere to
Use Avogadro's number which is numerically equal to ...
( 6.02 multiply by 10 to the power of negative 23)
Avocado's number is the number of particle(molecules, ions, atoms) present in one mole of substance.
number of molecule in 0.809 mole of h20 = ....
one mole of h20 contains (6.02* 10^-23)
0.809 mole contains....(6.02* 10^-23) (0.809)
which is equal to [4.951* 10 ^-23]
if I made no mistake in calculation...it must be correct
Answer : The value of
across the membrane is 6.80 kJ/mol
Explanation :
The relation between the equilibrium constant and standard Gibbs free energy is:

where,
= standard Gibbs free energy = ?
R = gas constant = 8.314 J/K.mol
T = temperature = 
= equilibrium constant
= concentration inside the cell = 
= concentration outside the cell = 
Now put all the given values in the above formula, we get:



Thus, the value of
across the membrane is 6.80 kJ/mol
