Answer:
23.92 g
Explanation:
Molar mass of H2SO4 = (2×1)+32+(16×4)= 2+32+48= 82g/mol
H2SO4 + 2NaOH ---> Na2SO4 + 2H2O
I mole of H2SO4 = 2 moles of NaOH
24.5/82 = 24.5/82 × 2
= 0.598 moles of NaOH will neutralize
Mass= mole× molar mass
Molar mass of NaOH= 23+16+1 = 40g/mol
Mass= 0.598 × 40 = 23.92g of NaOH
a)
26C5 -> 26 choices of 5 things
b)
15C1 × 11C4
c)
11C1 × 15C4
d)
11C2 × 15C2
e)
11C4
or
15C4
These are the factor that you observe or measure.
Lewis acid and Lewis base are most closely associated with ELECTRON TRANSFER.
A Lewis acid is any substance which can accept a pair of non bonding electron. A good example of a Lewis acid is hydrogen ion, H+. A Lewis base on the other hand is any specie which can donate a pair of electron. Thus, in Lewis theory of acid and base reaction, bases donate pairs of electrons and acids accept the pairs of electrons. Ammonia is a good example of a Lewis base.
