Some one help me please I'm stuck Show using two conversion factors how you would convert from 0.020 kg into mg.
julia-pushkina [17]

Answer:

=2.0x10^4mg

Explanation:

Hello there!

In this case, when performing units conversions involving two proportional factors we need to make sure we first convert to the base unit and then to the target one; thus, since 1 kg = 1000 g and 1 g = 1000 mg, we set up the following expression:

=0.020kg*\frac{1000g}{1kg} *\frac{1000mg}{1g} \\\\=2.0x10^4mg

Best regards!

The cytochromes are heme‑containing proteins that function as electron carriers in the mitochondria. Calculate the difference in
Contact [7]

Answer:

DeltaG0 = -(1) X 96485 X 0.034 = -3280.49 J /mole = -3.281 KJ / mole

Explanation:

E0cell = E0cathode - E0anode

the cathode will be with more reduction potential and anode will have low reduction potential

E0cell = 0.254 - 0.220 = 0.034 V

Now

DeltaG0 = -nFE0cell

E0cell = 0.034 V

F = 96485 C

n = 1

Putting values

DeltaG0 = -(1) X 96485 X 0.034 = -3280.49 J /mole = -3.281 KJ / mole
