Both feed into other bodies of water
Answer:
180.845 mol
Explanation:
Molar mass of Ca: 40,078 g/mol
Molar mass of C: 12,0107 g/mol
Molar mass of O: 15,999 g/mol
Molar mass of CaCO3: (40,078+12,0107+3×15,999) 100,0857 g/mol
The number of moles= mass of bag in g ÷ molar mass of CaCO3
⇒ n= (18.1×1000)÷100,0857 = 180.845 mol
Answer:
Normally, it explains that matter cannot be created or destroyed. It demonstrates different chemical reactions that help show the different transformations of the matter but will never destroy it or create it.
The balanced chemical
reaction will be:
C3H8 + 5O2 = 3CO2 +4H2O
We are given the amount of propane gas to be burned. This will be
our starting point.
<span>0.025 g C3H8 ( 1 mol C3H8 / 44.1 g C3H8 ) ( 5 mol O2/1
mol C3H8)(32 g O2 / 1 mol O2) = 0.09 g O2</span>
