The coefficient of Oxygen in the balanced reaction : 3
<h3>Further explanation</h3>
Given
Reaction(unbalanced)
C2H4+ O2--> CO2+H2O
Required
The coefficient of Oxygen
Solution
C₂H₄+ aO₂⇒ bCO₂+cH₂O
C, left=2, right=b⇒b=2
H, left=4, right=2c⇒2c=4⇒c=2
O, left=2a, right=2b+c⇒2a=2b+c⇒2a=2.2+2⇒2a=6⇒a=3
The equation becomes :
<em>C₂H₄+ 3O₂⇒ 2CO₂+2H₂O</em>
Answer:
Explanation:
Speed of light = Wavelength x Frequency.
605 nm x Frequency = 3x10^8 m/s
6.05 x 10^-7 m x Frequency = 3x10^8 m/s
Frequency = 4.96 x 10^14 Hz
Maybe 47.999 g if I can’t I’m sorry.
Hey there !
Answer BChemical properties are
characteristic behaviors of a substance when it is found in the presence of
another substance. To investigate chemical properties we will have to carry out
chemical transformations (performing chemical tests) and it is generally not
possible to recover the sample used (because it suffers changes giving rise to
other substances).
