Is burning octane exothermic or endothermic?
Burning octane is an exothermic reaction because it releases energy in the form of heat and light as it reacts with oxygen to form carbon dioxide and water.
What is produced when hydrocarbons combust?
CO, CO2, H2O and more comlicated structures.
What weight of water is produced burning 19.8grams of octane?
The formula for normal octane is C8H18. Its molar mass is 114.23 g mol−1 The formula for its combustion is 2C8H18 + 25O2 --> 16CO2 + 18H2O So 1 mole of octane gives 9 moles of water. One mole of water has a mass of 18 g 19.8 g of octane is 114.23/19.8 moles so its combustions gives ((114.23/19.8) x 9 x 18 ) = 934.61 g of water
Why does carbon get produced when a Bunsen burner is on a safety flame?
The oxygen necessary for burning is not sufficient.
What is produce in photosynthesis?
OxygenFood (glucose)Starch (excess food/glucose)
Word equation for the reaction for the burning of octane in air?
octane + oxygen --> water + carbon dioxide
Is burning octane exothermic or endothermic?
Burning octane is an exothermic reaction because it releases energy in the form of heat and light as it reacts with oxygen to form carbon dioxide and water.
What colour flame would indicate ethane burning in excess oxygen?
A blue flame would indicate ethane burning in excess oxygen. Blue flames are typically associated with complete combustion and sufficient oxygen supply during the burning process.
What is the mass of heavy water produced when 7.00grams of oxygen reacts with excess D2?
The mass of heavy water produced when 7,00grams of oxygen reacts with excess D2 is 7,875 g.
What is produced when hydrocarbons combust?
CO, CO2, H2O and more comlicated structures.
What is the word equation for octane plus oxygen?
Octane + oxygen ---> carbon dioxide + water Lulu
What element is black and is produced when there is incomplete burning?
Carbon is the element that is black and is produced when there is incomplete burning.
What are two products formed when lavandulol is burnt in excess oxygen?
Carbon Dioxide & Water, Complete burning with excess of oxygen gives out Carbon Dioxide(CO2) + Water , While incomplete burning with limited amount of oxygen gives out Carbon monoxide (CO) + Water
What weight of water is produced burning 19.8grams of octane?
The formula for normal octane is C8H18. Its molar mass is 114.23 g mol−1 The formula for its combustion is 2C8H18 + 25O2 --> 16CO2 + 18H2O So 1 mole of octane gives 9 moles of water. One mole of water has a mass of 18 g 19.8 g of octane is 114.23/19.8 moles so its combustions gives ((114.23/19.8) x 9 x 18 ) = 934.61 g of water
When oxygen is available sulfur dioxide is produced from the burning of sulfur.what is the equation for this?
The equation for the burning of sulfur in the presence of oxygen to produce sulfur dioxide is: S (sulfur) + O2 (oxygen) --> SO2 (sulfur dioxide).
Why does carbon get produced when a Bunsen burner is on a safety flame?
The oxygen necessary for burning is not sufficient.
0.400mol of octane is allowed to react with 0.800mol of oxygen Which is the limiting reactant?
To determine the limiting reactant, compare the moles of each reactant to the stoichiometry of the balanced. In this case, the balanced equation is: 2 C8H18 + 25 O2 → 16 CO2 + 18 H2O The moles ratio between octane (C8H18) and oxygen (O2) is 2:25. Calculate the ratio for each reactant: Octane: 0.400 mol * (25 mol O2 / 2 mol C8H18) = 5.00 mol O2 needed Oxygen: 0.800 mol O2. Since the actual moles of oxygen available (0.800 mol) are greater than the moles needed for the reaction with octane (5.00 mol), oxygen is in excess and octane is the limiting reactant.
