H₂SO4:
m=10g
M=98g/mol
n = m / M
n = 10g / 98g/mol = 0,102mol
V=0,1L
Cm = n / V = 0,102mol / 0,1L = 1,02M
The reaction of hydrogen gas (H2) with oxygen gas (O2) is a COMBINATION or SYNTHESIS reaction, because multiple substances combine to form fewer substances. Here, the two gases form one substance, water (H2O):
2H2 + O2 -- > 2H2O
