Answer:
nitrogen compounds in the air
Explanation:
The element is Chromium because it contains 26 protons
The mass chloride is 3.456 grams
calculation
Step:1 calculate the moles of TiCl3
moles = molarity x volume in liters
volume in liters = 100 ml /1000 = 0.1 L
molarity = 0.325 M = 0.325 mol / L
moles is therefore = 0.1 L x 0.325 mol /L = 0.0325 moles
step 2: find the moles of Cl
since there is 3 atoms of cl in TiCl3 the moles of Cl
= 3 x 0.0325 =0.0975 moles
Step 3: calculate mass of cl
mass= moles x molar mass
=0.0975 moles x 35.45 g/mol = 3.456 g
Answer:
15.71g
Explanation:
The general combustion equation for all hydrocarbons is
CxHy + (x+y/4) O2 = xCO2 + (y/2) H2O
For octane, C8H18 :
C8H18 + ( 8 + 18/4 ) O2 = 8CO2 + 9H2O
C8H18 + 50/4 O2 = 8CO2 + 9H2O
C8H18 + 25/2 O2 = 8CO2 + 9H2O
2C8H18 + 25 O2 = 16 CO2 + 18H2O (balanced)
From the balanced equation,
2 x 22.4 L of octane produced 16 [ 12 + (16 x 2)] of carbon dioxide
That is,
44.8 L of octane produced 704g of carbon dioxide
So, 1L of octane will produce 1 L x 704g/44.8 L = 15.71g of carbon dioxide
Therefore, 15.71g of carbon dioxide will be produced by the complete combustion of 1 L of octane.
