What is C3H8 plus O2CO2 plus H2O? The balanced form of this equation is: C3H8 + 5 O2 = 3 CO2 + 4 H2O If you mean how you would read this, it would be: Propane combined with oxygen produces carbon dioxide and water vapor.C3H8. Molar MassSo, you must not balance the C3H8 (1 mole of C3H8). Try multiples of 3 on the CO2..You then need 8 H's on both sides so try a 4 on the H2O..Then, we take ratio between C3H8 : CO2 to find the number of mole of CO2 produced. They have 1:3 ratio, so we will get (0.159 * 3 = 0.477)moles of CO2. For final answer, we need to convert moles to grams.CO2 + H2O. Выполните умножение: 1)-2c²d^4(4c²-c³d+5d^4) 2)(5m³n-8mn²-2n^6) *(--4m²n^8).

Наверное, так: C3H8 + 5 O2 = 3 CO2 + 4 H2O Удачи!In this video we'll balance the equation C3H8O + O2 = CO2 + H2O and provide the correct coefficients for each compound.To balance C3H8O + O2 = CO2 + H2O you'...Under certain circumstances, carbon dioxide, CO2(g), can be made to react with hydrogen gas, H2(g), to produce methane, CH4(g), and water vapor, H2O(g): CO2(g)+4H2(g)→CH4(g)+2H2O(g).The first step would be to balance out the carbons on the products side by multiplying CO2 by 3. The new equation will be C3H8 + 02 ----> 3CO2 + H20. Now, the carbons are balanced, we will look at the hydrogens. We can multiply the number of waters on the product side by 4, to make 4 H20 molecules.

How can I balance this C3H8 + O2 -> CO2 + H2O + heat?

The answer is : C3H8 + 5O2 ==> 3CO2 + 4H2O The total number of atoms one element contains on the reactant side should add up to the total number I learnt this way for combustion of hydrocarbons from my teacher. Make the number of C and H atoms the same as the left side C3H8 + O2 -----> 3...If there is an insufficient amount of oxygen or air, then incomplete combustion occurs. Incomplete combustion will occur if C3H8 burns in the presence of 4O2 instead of 5O2. The products of this reaction are water, carbon monoxide and carbon. Carbon is released into the air as soot and carbon...C_3 H_8 + 5O_2 ->3CO_2 +4H_2 O This equation represents the combustion of proprane (a 3 carbon alkane) and it it highly exothermic, gives off heat, delta H < 0.C3H8 + 5O2 ---> 3CO2 + 4H2O O2 - Limiting Reactant How Many Molecules Of CO2, H2O, C3H8, And O2 Will Be Present If The Reaction Goes To Completion? how many molecules of CO2, H2O, C3H8, and O2 will be present if the reaction goes to completion?Химия. Баланс C_3H_8+O_2=CO_2+H_2O.

First, we need to convert grams of each reactant to moles.

When we convert grams to moles or moles to grams, we use molar mass.

The molar mass of O2 is 16.0g/mol, C3H8 is 44.1g/mol

-> O2 : 98.0g / (16.0 g/mol) = 6.Thirteen mol

-> C3H8 : 7.00g / (44.1g/mol) = 0.159 mol

Now, we want to find which one is restricting reactant.

From balanced equation, we get 1:Five ratio between C3H8 : O2.

If we assume C3H8 is restricting reactant, we will be able to eat 0.159 moles (all) and (0.159moles * 5 = 0.795)moles of O2. Since we've sufficient amount of O2 for this reaction, our assumption used to be proper.

Therefore, C3H8 is limiting reactant and O2 is excess reactant.

Then, we take ratio between C3H8 : CO2 to find the choice of mole of CO2 produced.

They have 1:Three ratio, so we can get (0.159 * 3 = 0.477)moles of CO2.

For final answer, we want to convert moles to grams.

The molar mass of CO2 is 44.01g/mol.

-> 0.477mol * 44.01g/mol = 21.Zero g

Answer : 21.0g of CO2

Hope that is helpful! :)
