What type of reaction is 2C6H6 15O2 12CO2 6H2O?
balanced combustion reaction for C6H6 Equation: 2C6H6(l)+15O2(g)–> 12CO2+6H2O(l)_6542 KJ.
How many grams of CO2 is formed in the chemical reaction?
So, to convert between moles and grams, use the molar mass of the two compounds. If one mole of carbon monoxide has a mass of 28.01 g and one mole of carbon dioxide has a mass of 44.01 g , it follows that the reaction produces 44.01 g of carbon dioxide for every 28.01 g of carbon monoxide.
What does a balanced chemical equation allows one to determine?
A balanced chemical equation gives the identity of the reactants and the products as well as the accurate number of molecules or moles of each that are consumed or produced.
What are the products of a combustion reaction?
Combustion reactions always have two products: carbon dioxide and water.
What is the product of the combustion of hydrogen?
water vapor
The combustion of hydrogen gas produces water vapor. Notice that this reaction also qualifies as a combination reaction.
What is the stoichiometric factor between CH4 and H2O in the following balanced equation CH4 2o2 CO2 2h2o?
2.81g. Explanation: The coefficients in the balanced chemical equation can be used as the stoichiometric factor between CH4 and H2O.
Why must a chemical equation be balanced to solve stoichiometry problems?
All stoichiometric calculations begin with a balanced equation. Balanced equations are necessary because mass is conserved in every reaction. The number and kinds of atoms must be the same in the reactants and products.
How is hydrogen gas produced from fossil fuels Mcq?
5. How is hydrogen gas produced from fossil fuels? Explanation: Hydrogen gas is produced from fossil fuels by different techniques like partial oxidation of methane, steam reforming and coal gasification. Biomass gasification and electrolysis produce hydrogen gas in small quantities.
What is the balanced chemical equation for photosynthesis?
Carbon dioxide + Water → Glucose + oxygen.
Is CH4 O2 → CO2 H2O balanced?
They are not balanced. There are 4 H atoms on the left side and 2 H atoms on the right. Place a coefficient of 2 in front of the H2O . We now have 4 H atoms on both sides.
What are the basic steps in balancing chemical equations?
