Data:
M (molarity) = ? (M or Mol/L)
m (mass) = 13.50 g
V (volume) = 250 mL → 0.25 L
MM (Molar Mass) of Lead(IV) Nitrate
Pb = 1*207 = 207 amu
N = (1*14)*4 = 14*4 = 56 amu
O = (3*16)*4 = 48*4 = 192 amu
------------------------------------
MM of
= 207+56+192 = 455 g/mol

Answer:
<span>
B. 0.119 M</span>
<span>The correct answer is( A) blood.
when the buffer solution its PH value changes very little when a small amount
of strong acid or base is added to it, and here the bicarbonate buffering system is used to regular the PH of the blood that keeping the PH at nearly constant value by maintaining the original acidity or basicity of the solution.</span>
the products formed from the reaction
all of the above
Answer:
Compass - Gps
Explanation:
I belive the pro's and cons are
GPS you are trusting a little man made device
the direction you to give you directions
are going on and that it won't break or die
a device not a paper map
Compass
You can see north east south and it is usually carefully crafted for o outdoors but it has no roads and
west on the compass and if given no directions, extremely
you can see the roads follow directions confusing until you learn it
like go south then east.
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe.
