Answer:
True I think... I hope I have helped you out a little bit :)
Explanation:
They are examples of elements because there's only one molecule in both
So in order to answer this we need the number of moles of oxygen and the right stoichiometry.
The balanced reaction should be 2HgO --> 2Hg + O2, therefore 2 moles of mercury are produced for every one mole of oxygen gas. Since we have the mass of O2 we can calculate the moles as moles = mass/RMM where RMM is the relative molecular mass of O2, which is 32 g/mol. Therefore the number of moles = 125/16 = 3.9 mol.
Since 2 moles of Hg are produced for every one mole of O2, the number of moles of Hg = 3.9*2 = 7.8 mol.
<span>Homeostasis occurs when the solute concentration is equal on either side of the cell barrier. This allows water to move in and out of the cell at equal rates. There is no net movement of water during homeostasis.</span>
Answer:
CH₃COO ⁻ + H₂O ⇔ CH₃COOH + OH⁻
Base Acid Conjugated weak acid Conjugated base
Explanation:
Acetate is a Bronsted-Lowry base because it can accept a proton from water.
This makes the solution be basic, because it release hydroxides.
CH₃COO ⁻ + H₂O ⇔ CH₃COOH + OH⁻
Base Acid Conjugated weak acid Conjugated base
Water becomes an acid, because it can release a proton, following the Bronsted-Lowry theory.
