Is this equation completely balanced? 2C8H8 + 25O2 8CO2 + 18H2O No, because the number of carbon, hydrogen & oxygen atoms on
Sergio039 [100]
<span>So to make it clear let's break the equation down species by species and assess the number of each species on bothe sides of the equation:
                   2C</span>₈H₈  +  25O₂   →   8CO₂ +  18H₂<span>O
LHS:  C - 16                                           RHS:  C - 8
          H - 16                                                     H - 36
          O - 50                                                    O - 34

Thus based on that it is evident that the equation is not quite balanced.  This therefore means a "</span><span>No, because the number of carbon, hydrogen & oxygen atoms on both sides of the equation are not equal."

</span>The actual balance equation would be C₈H₈  +  10O₂   →   8CO₂ +  4H₂O

Red lights on a traffic light have a frequency of 4.3 X 10^15 Hz. What is the red light’s wavelength in meters? (Speed of light
Juliette [100K]

Answer:

The correct answer to this problem is B. 7.0 X 10^-8 meters

Explanation:

To solve this problem, we have to use the following equation:

c = λν, or speed of light = wavelength*frequency

If we substitute in the values we are given by the problem, we get:

3.00 * 10^8 m/s = (4.3 * 10^15 Hz)*(wavelength)

wavelength = 6.98 * 10^-8 m

Since the given value has 2 significant figures, our answer should similarly include two significant figures since the operation in the problem was multiplication.

Therefore, the answer is B. 7.0 X 10^-8 meters.

Hope this helps!

How many particles are in chemicals
stepan [7]

Answer:

6.022 x 10^23 particles

Explanation:

Chemists have chosen to count atoms and molecules using a unit called the mole (mol), from the Latin moles, meaning “pile” or “heap.”

One mole is 6.022 x 10^23 of the microscopic particles which make up the substance in question.

Hope this helped! :^)

If a microwave oven emits 1,100 J of energy every second, how long will it take for the microwave to emit 4650 J of energy? Expr
icang [17]

Answer:

Time = 4.2273 seconds

Explanation:

The amount of the energy emitted by the microwave = 1100 J/s

It means that :

1100 J of the energy is emitted in 1 second

Also,

1 J of the energy is emitted in [tex]\frac {1}{1100}[tex] second

To calculate:

Time for emitting 4650 J of energy

Thus,

4650 J of the energy is emitted in [tex]\frac {1}{1100}\times 4650[tex] second

<u>Time = 4.2273 seconds</u>
