The balanced equation for the above reaction is as follows;
4HCl + O₂ ---> 2H₂O + 2Cl₂
stoichiometry of HCl to O₂ is 4:1
number of HCl moles present - 63.1 g / 36.5 g/mol = 1.73 mol
number of O₂ moles present - 17.2 g / 32 g/mol = 0.54 mol
if HCl is the limiting reactant; then number of O₂ moles = 1.73/4 = 0.43 mol
There are 0.54 mol present and only 0.43 mol are required to react. Therefore HCl is the limiting reactant and O₂ is in excess.
Answer:
180º
Explanation:
Carbon has 4 valence electrons and to complete the octet requires 4 more , so it will share with the oxigen atoms 4 more, forming a single and a pi bond similar to CO2
Since the carbon does not have lone pairs, the geometry around this central atom will be linear and the angle will be 180 , S = C = S
0.625 moles of ge X 6.02x10^23 atoms/ 1 mol of ge equal to 3.76x10^23 atoms of ge, just times with Avogadro.
The answer would be 200000 J. the equation for kinetic energy is 1/2 mass times velocity squared. 1/2 of 1,000 is 500. and 20*20 is 400. So, multiply 400 by 500, and that gives you your answer,
