How many moles of O2 are needed to react completely with 35.0 mol C2h2
Wittaler [7]

Hey There!:


2 C2H2 + 5 O2 = 4 CO2 + 2 H2O


2 moles C2H2 ----------- 5 moles O2

35.0 moles C2H2 ------- moles O2


moles O2 = 35.0 * 5 / 2


moles O2 = 87.5 moles


hope this helps!

Which of the following is one part of a chemical formula for a molecule?
solniwko [45]

D

Explanation:

An example is a chemical formula of a compound NH₄NO₃

These subscript numbers mean that there four (4) hydrogen atoms and three (3) oxygen atoms in the molecules.

A Lewis dot diagram for the molecule is used to show the electrons of the atoms, and their interactions – such as in covalent bonding- in the molecule

calculate the volume of air in liters that you might inhale(and exhale)in 8.0 hours. Assume that each breath has a volume of 0.5
maks197457 [2]
Formula:
0.57 liters = 1 breath(17 breaths = 1minute)(60 minutes = 1 hour)(8 hours) = 4651.2 liters

each breath is 0.57 liters
He or she exhales 17(0.57) = 9.69 liters in a minute
in an hour, he or she exhales 9.69(60) liters in a minute = 581.4 liters
Answer = in 8 hours he or she exhales, 581.4(8) = 4651.2 liters in 8 hours


Hope that answers your question!!!!have a great day!!!

This type of fatty acid has at least one double bond in the carbon-to-carbon chain and also contains protective qualities
Sloan [31]
There are two general classifications of fatty acids according to their structure: saturated and unsaturated fatty acids. Unsaturated fatty acids are those that contain at least one of either a double or triple bond. Therefore, the answer to this questions is: unsaturated fatty acid. Its function is to protect the organs as a cushion, or as storage area for excess energy.

4.0 L of He(g), 6.0 L of N2(g), and 10. L of Ar(g), all at 0°C and 1.0 atm, are pumped into an evacuated 8.0 L rigid container,
lesantik [10]

Answer:

The final pressure in the container at 0°C is 2.49 atm

Explanation:

We apply the Ideal Gases law to know the global pressure.

We need to know, the moles of each:

P He . V He = moles of He . R . 273K

(1atm . 4L) / R . 273K = moles of He  → 0.178 moles

P N₂ . V N₂ = moles of N₂ . R . 273K

(1atm . 6L) / R . 273K = moles of N₂ → 0.268 moles

P Ar . V Ar = moles of Ar . R . 273K

(1atm . 10L) / R . 273K = moles of Ar → 0.446 moles

Total moles: 0.892 moles

P . 8L = 0.892 mol . R . 273K

P = ( 0.892 . R . 273K) / 8L = 2.49 atm

R = 0.082 L.atm/mol.K
