How many grams of oxygen gas will react with 77.28 grams of ethane in 2 C2H6 plus 7 O2 equals 4 CO2 plus 6H2O?
First, find out how many moles of C2H6 that you have: Carbon is 12 grams per mole, and H is 1 gram per mole, so C2H6 is (2*12 + 6*1)grams = 30 grams per mole. So you have (77.28/30 = 2.58) moles. Every 2 moles of C2H6 reacts wilth 7 moles of O2 so it will react with 7/2*2.58 moles = 9.02 moles of O2.O2 is 32 grams per mole, so (9.02 moles)*(32 grams/mole) = 288.64 grams.
How many atoms in 6O2?
There are 12 atoms in 6 O2 molecules.
How many atoms are in O2 2H2 2H2O?
2 oxygen,4 hydrogen, 4 hydrogen, and 2 oxygen so overall 12
The are 6 grams of carbon and 20 grams of oxygen if 22 grams of carbon dioxide are produced and all the carbon is used how many grams of oxygen are left?
If 12 grams of carbon were used to form the 22 grams of carbon dioxide, this implies that 12 grams of oxygen were consumed in the reaction. Since 20 grams of oxygen were initially available, only 8 grams of oxygen are left unused.
How many moles of oxygen are needed to completely react with 6 moles of hydrogen?
The balanced chemical equation for the reaction between hydrogen and oxygen is: 2H2 + O2 -> 2H2O This equation shows that 1 mole of O2 reacts with 2 moles of H2. So, to completely react with 6 moles of H2, you would need 3 moles of O2.

When carbon is burned in the presence of oxygen the carbon and oxygen combine to prodon dioxide if you start w 6 grams of carbon and 16 grams of oxygen and they react completely how many grams of car?
the equation of this reaction is C + O2 = CO2 (s) (g) (g) according to this reaction 1mol of Carbon react with same number of moles of Oxygen. and this combination gives 1mol of CO2 as result. so first we have to find the number of moles in the weight we are going to use. 12 grams of carbon contains 1mol so 6 grams of carbon contains ( 1/12 )*6 = 0.5mol 32 grams of Oxygen contains 1mol 16 grams of Oxygen contains ( 1/36 )*16 = 0.5mol as 1mol of C react with 1mol of O2,0.5mol of C react with 0.5mol of O2. this produces equal number of moles (0.5mol) of CO2.

What does subscription?
The subscript on an element indicates how many atoms of the element are present: ex: O2 - the 2 shows there are two oxygen's present C6H12O6(sugar)- there are 6 carbon 12 hydrogen and 6 oxygen
How many moles are present in 288 grams of oxygen?
Oxygen is a diatomic gas, so a molecule of oxygen contains two oxygen atoms.One oxygen atom has an atomic weight of 16.00 amu (atomic mass units), so diatomic oxygen has a molecular weight of 16.00 × 2 or 32.00 amuamu (a.k.a., molar mass) are in units of grams/mol, so by dividing:8.0 g O2 ÷ 32.00 g/mol O2 = 0.25 mol O2One mol contains 6.022 × 1023 molecules (Avogadro's number), which can be multiplied by our 0.25 mol O2 to get the number of moles in 8.0 grams O2:0.25 mol O2 × (6.022 × 1023) = 1.5055 × 1023 moleculesDon't forget to round to two significant figures (limited in precision by the 8.0 grams given):There are 1.5 x 1023 molecules of O2 in 8.0 grams of O2
