Explanation:
it's gotta be because... let me get back on it.
Answer: B
Explanation:
According to Ohm's Law, the answer is B.
Ohm's Law states that power is equal to volume x current.
If volume x current equals power, that means they are both 50% of power.
Ohm's Law:
power = voltage x current
current = voltage x power
voltage = power x current

Answer:
0.67mol/Kg
Explanation:
The following were obtained from the question:
Mole of solute = 0.50mol
Mass of solvent = 750g = 750/1000 = 0.75Kg
Molality =?
Molality = mole of solute /mass of solvent
Molality = 0.5/0.75
Molality = 0.67mol/Kg
Water. The energy from the fission reaction is used to heat water. The water vaporizes which causes pressure rise. The pressure is used to drive a turbine which runs a generator.
I hope this helps.
First, we have to calculate the number of moles of H2SO4 in the solution:
V=60 mL = 0.06 L
c=5.85 mol/L
n=V×c=0.06×5.85=0.351 mol
Then we need to find the molar mass of H2SO4:
2×Ar(H) + Ar(S) + 4×Ar(O) =
=2 + 32 + 64 = 98 g/mol
Finally, we need to find the mass of H2SO4:
m=0.351 × 98 = 34.398 g
