The product of the complete combustion of any fuel (in this case, acetylene) are indeed water and carbon dioxide.
Balancing the combustion reaction,
C2H2 +(5/2) O2 --> 2CO2 + H2O
The number of moles of C2H2 will be,
(12 g) x (1 mole/26 g) = 6/13 mole
Then, the number of moles of O2 is,
(12 g) x (1 mole/32 g) = 3/8 mole
Therefore the limiting reaction is the O2. Getting the amount of CO2 and H2O produced from balancing,
CO2 = (3/8 moles) x (2 moles CO2/ 5/2 mole O2)(44 g/ 1 mole) = 52.8 g
H2O = (3/8 moles) x (1 mole / 5/2 mole O2)(18 g / 1 mole) = 2.7 g

URGENT PLEASE HELP!! Earth science!!
What stages of development are represented by the Group 2 and Group 3 stars? Describe these
groups in terms of their relative age, size, brightness, and temperature.
Answer:
In a nonpolar covalent bond, the atoms share electrons equally with one another.
Explanation:
Nonpolar covalent bonds are a type of bond that occurs when two atoms share a pair of electrons with each other. These shared electrons glue two or more atoms together to form a molecule.
Aluminum has three electrons in its valence shell. if you look at the periodic table, there are numbers at the top. in column 2, the elements have 2 valence electrons, in column 3 they have 3 valence electrons etc.
Being at the beach: Joyous, thrilled - Smiling, jumping (for joy)
Seeing a tornado nearby: Terror, despair - Crying, shaking
Crossing paths with a grizzly bear: Doom, hopelessness - Frozen, sweating
Skydiving: Anxious, excited - Fidgeting, nervous laughter
Noticing a suspicious figure...: Suspicious, frightened - Observing, running
Seeing a neighbors house on fire: Pity, distress - Frowning, shaking
Seeing two dogs..: Affectionate, happiness - Smiling, giggling
Receiving money: Surprised, relieved - Jumping for joy, crying
Fight or flight response, tornado, grizzly bear, fire, suspicious figure, - maybe skydiving if you chicken out?
These are all opinions though hopefully this helps.
