Answer:
5250 Joules
Explanation:
Mass = 50g
Initial Temperature = 125.0 degrees Celsius
Final Temperature = 100 degrees Celsius
Temperature change = Final - Initial = 100 - 125 = -25
Heat = ?
These quantities are related by the equation;
H = mCΔT
where c = specific hear capacity = 4.2 J/g°C
H = 50 * 4.2 * (-25)
H = -5250 J (The negative sign is because heat is being released)
The reduced forms of the electron carries NAD+ / NADH and FADH / FADH2 have high potential energy.
- NAD& FAD used to donate electrons as a reducing agent, they receive electrons from other molecules and then became reduced.
-FAD is called flow in adenine dinucleotide, it is a redox cofactor and it is in many important enzymatic reactions in metabolism.
Answer:
Well ads I remember, the motion of the gas particles is random and in a straight-line. A sample of gas is contained in a closed rigid cylinder.
And here is what I found too -
According to Kinetic Molecular Theory, gaseous particles are in a state of constant random motion; individual particles move at different speeds, constantly colliding and changing directions. We use velocity to describe the movement of gas particles, thereby taking into account both speed and direction.
Answer:
27,397.23 L would be needed for a successful trip.
Explanation:
The problem gives us <u>the density (ρ) of the fuel,</u> by telling us that there are 803 g of fuel in 1 L, in which case:
ρ=
The required mass of fuel is 2.2 * 10⁴ kg, we can convert this value into g:
2.2 * 10⁴ kg * 
= 2.2 * 10⁷ g
We calculate the required volume (V), using the mass and density:
Thus 27,397.23 L would be needed for a successful trip.
