Answer:
120.44 × 10²³ molecules
Explanation:
Given data:
Moles of C₃H₈ = 5.0 mol
Molecules of water produced = ?
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Now we will compare the moles of C₃H₈ and water.
C₃H₈ : H₂O
1 ; 4
5 : 4×5 = 20 mol
Molecules of water:
1 mole = 6.022 × 10²³ molecules
20 mol×6.022 × 10²³ molecules / 1 mol
120.44 × 10²³ molecules
Chlorine gas, or dichlorine, is composed of 2 chlorine atoms and has a molar mass of 70.96, or about 71 g. So the answer is the molar mass is 71 g.
Hope this helps!
Answer:
Natural gas combustion equation:
CH4 + O2 ==> CO2 + 2 H2O + HEAT
Octane or oil combustion equation:
2C8H18 + 25 O2 ===> 16CO2 + 18 H2O.
If these fuels were replaced by self-sustaining energy sources, the contamination of the environment would be less, since their combustion generates toxic compounds that damage the ozone layer, promoting the greenhouse effect, increasing the Earth's temperature and also promoting the increase in the passage of ultraviolet radiation.
Explanation:
The combustion reactions are exothermic, and irreversible, they can be complete and incomplete combustions.
They always consist of oxygen as a reagent and water and carbon dioxide as a product (complete), in the case of the incomplete the difference is that the products vary and there may be waste or chemical compounds that failed to burn.
I believe the closest possible answer to this question are:Gas A effuses faster than gas B.The molar mass is directly proportional to the rate of effusion.Thank you for your question. Please don't hesitate to ask in Brainly your queries
