False because I think it’s supposed to be photoheteroterotrophs
Answer:
c and d, are you supposed to check 3? or only 2?
Mole ratio:
<span>2 H2 + O2 = 2 H2O
</span>
2 mol H2 ---------- 1 mol O2
1.67 mol H2 ------ ??
1.67 x 1 / 2 => 0.835 moles of O2
<span>If a psychoactive substance is used or abused over a long period of time, a person may be unable to function properly without it. An abuser can suffer extreme withdrawals.</span>
Molality is simply defined as the number of moles of
solute over the mass of the solvent.
In this case the solute is NaCl and the solvent is water,
therefore:
moles solute = 0.630g/ 58.44 g/mol = 0.0108 mol
So the molality is:
m = 0.0108 mol / (0.525 kg)
<span>m = 0.0205 molal</span>
