Answer:
So, graphene is fundamentally one single layer of graphite; a layer of sp2 bonded carbon atoms arranged in a honeycomb (hexagonal) lattice.

<span>Answer:
We heated up the liquid CFC from 11.05 degrees celsius to its boiling point (47.6 degrees)
That means we heated it up 36.55 degrees
The formula to solve this is C = Q / M x dT
where
C is the specific heat of the liquid CFC (.91 J/G/C)
Q is the amount of heat required (what we're trying to find out)
M is the mass (52.5 grams)
and dT is the temperature difference (36.55 degrees)
Now put in the values and find out what Q is
.91 = Q / 52.5 x 36.55
.91 = Q / 1918.875
Q = 1746.17 joules to heat up the liquid CFC</span>

Explanation:
5 moles because molarity signifies number of moles dissolved in One litre of water
Answer:
Acid + Oxide or Hydroxide
Many oxide, hydroxide and carbonate compounds
are insoluble in water, but do react with acid.
Acid + Oxide → Salt + Water
Acid + Hydroxide → Salt + Water
MgO (s) + HNO3 (aq) → Mg(NO3)2 (aq) + H2O (l)
CuOH (s) + HCl (aq) → CuCl (aq) + H2O (l)
Explanation:
lead compounds are the oxides: lead monoxide, PbO, in which lead is in the +2 state; lead dioxide, PbO2, in which lead is in the +4 state; and trilead tetroxide, Pb3O4. Lead monoxide exists in two modifications, litharge and massicot. Litharge, or alpha lead monoxide, is a red or reddish…
