The universe moves with the energy left off from the big bang. This is why the universe constantly expands.
Things rotate and revolve because of gravity.

Answer:
HPO42- (aq) + NH4+ (aq)
Explanation:
This is a conjugate acid-base pair. Please forgive if my answers are incorrect. I myself am quite unsure.
Answer:
see explanation
Explanation:
a. Molar Mass = ∑Atomic Masses = 12C + 22H + 11O = 12(12) + 22(1) + 11(16) = 144 + 22 + 176 = 342 g/mole
b. For 100ml of 0.10M solution => Molarity x Volume (liters) = moles needed x mole weight = grams solute needed for 100ml solution. This can be given by the expression ...
mass solute needed (g) = Molarity needed x Volume needed in liters x mole wt of solute = (0.10M)(0.100L)(342g/mole) = 3.42 grams solute.
mixing => Transfer 3.42 grams of solute (C₁₂H₂₂O₁₁) into mixing container and add solvent (water) up to but not to exceed 100 ml total volume.
c. mass needed for 100ml of 0.50M solution = M·V·f.wt. = (0.50M)(0.100L)(342g/mole) = 1.71 grams solute. => mix as in 'b'.
Well asexual isn't "as" sexual as sexual reproduction
hope this helps :P :)
