Answer:
The free energy change for malate dehydrogenase reaction is -50kJ/mol
Explanation:
The malate dehydrogenase reaction is:
Malate + NAD⁺ ⇄ Oxaloacetate + NADH + H⁺
Where equilibrium constant, k, could be expressed as:
Replacing with the listed concentrations:
K = 3,713x10⁻⁹
ΔG° is defined as:
<em>ΔG° = RT ln K </em><em>(1)</em>
Where:
R is gas constant 8,314J/molK
T is temperature 310K
And K = 3,713x10⁻⁹
<em>ΔG° = -50000 J/mol ≡ </em>-50kJ/mol
I hope it helps!
Answer:
Explanation:
Ground state electron configuration of potassium (K) is 1s2 2s2 2p6 3s2 3p6 4s1. The valency of the element is determined by electron configuration in the excited state. This electron configuration shows that the last shell of the potassium atom has an unpaired electron (4s1). So the valency of potassium is 1.
Answer: A
Explanation: Im pretty sure it's A, if you're desperate, go ahead and take my advice. If you're not you probably shouldnt.

Answer:
374°F
463.15K
Explanation:
This particular Question wants to test knowledge on the conversion of the units of temperature from celsius degree to degree Fahrenheit. Also, the conversion of degree celsius to kelvin.
The value given which is 190 degree celsius can be converted into degree Fahrenheit using the formula below;
(x°C × 9/5 ) + 32.
Therefore, x = 190°C =( 190°°C × 9/5) + 32 = 374°F.
The conversion of degree celsius to kelvin is given below as;
x°C + 273.15 .
Therefore, x = 190°C = 190°C + 273.15 = 463.15K.
Therefore, the temperature needed to bake at Fahrenheit and kelvin are 374°F and 463.15K respectively.
