Answer:
0.027 moles of carbon dioxide produced by the reaction of 0.085 mol of oxygen.
Explanation:
Moles of oxygen gas = 0.085 mol
According to reaction, 50 moles of oxygen gives 16 moles of carbon dioxide gas, then 0.085 moles of oxygen gas will give:
of carbon dioxide
0.027 moles of carbon dioxide produced by the reaction of 0.085 mol of oxygen.
Explanation: Pollution in urban streams (commonly caused by improperly disposed waste and/or acid rain) always has a negative effect on the environment. <em>Urban rivers are extremely polluted in some areas</em>, such as India. Actions have been taken to clear the streams, and progress has been made.
Hope this helps!
Number of moles of CO2 =
Mass /Ar
= 50.2 / (12 + 32)
1.14 mols
For every 1 mol of gas, there will be
24000 cm^3 of gas
Vol. = 1.14 x 24 dm^3
= 27.36 dm^3
Answer:
16 g/mol
Explanation:
In CO2, it means we have 1 mole of carbon and 2 moles of oxygen.
However, we want to find the molar mass of just a single mole of oxygen.
Now, from tables of values of elements in electronic configuration, the molar mass of oxygen is usually approximately 16 g/mol.
In essence the molar mass is simply the atomic mass in g/mol
Hydrogen Bonding will effect the boiling point the most. Let's take an example Butane a four carbon unsaturated organic compound with molecular formula C₄H₁₀ and boiling point -1 °C.
H₃C-CH₂-CH₂-CH₃
Now, replace one hydrogen on terminal carbon with -OH group and convert it into Butanol.
H₃C-CH₂-CH₂-CH₂-OH
The Boiling point of Butanol is 117.7 °C. This increase in boiling point is due to formation of hydrogen bondings between the molecules of Butanol.
