How many moles of oxygen gas react to yield 0.200 mole water? . . C5H12(g) + 8 O2(g) = 5 CO2(g) + 6H2O(g)

1 answer:

4 0

C5H12(g) + 8 O2(g) = 5 CO2(g) + 6H2O(g)
molar ratio of H2O to O = 6:8
we have 0.200 moles of H2O so we need 0.200 * 8/6 moles of O2 = 0.267 moles of O2

Therefore, there will be 0.267 moles of O2 gas required to yield 0.2 moles of H20.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

a compound has an empirical formula of CH2 what is the molecular formula if it's molar mass is 252.5 grams/mol

Goryan [66]

Empirical formula is the simplest ratio of components making up the compound. the molecular formula is the actual ratio of components making up the compound.

the empirical formula is CH₂. We can find the mass of CH₂ one empirical unit and have to then find the number of empirical units in the molecular formula.

Mass of one empirical unit - CH₂ - 12 g/mol x 1 + 1 g/mol x 2 = 12 = 14 g

Molar mass of the compound is - 252 .5 g/mol

number of empirical units = molar mass / mass of empirical unit

= $\frac{252.5 g/mol}{14 g}$

= 18 units

Therefore molecular formula is - 18 times the empirical formula

molecular formula - CH₂ x 18 = C₁₈H₃₆

molecular formula is C₁₈H₃₆

If a sample containing 2.00 mL of nitroglycerin (density=1.592g/mL) is detonated, how many total moles of gas are produced?

fgiga [73]

The overall balanced chemical reaction for this is:

Detonation of Nirtoglycerin 
4 C3H5N3O9 --> 12 CO2 + 6 N2 + O2 + 10 H2O

Therefore:

2.00 mL x 1.592 g/mL = 3.184 g 
3.184 g / 227.1 /mol = 0.0140 mol nitroglycerin
4 moles --> 12 + 6 + 1 + 10 = 29 moles of gas
0.0140 mol x (29/4) = 0.1017 moles of gases or (0.102 mol)

When are atoms considered to be stable?

Sergio [31]

Answer:

Atoms are at their most stable when their outermost energy level is either empty of electrons or filled with electrons.
