Which color of light has the greatest energy

1 answer:

ozzi3 years ago

4 0

Answer:

violet

Explanation:

Waves with a short wavelength have the most energy. Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter - roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy (google)

Which chemical equation best represents the Law of Conservation of

astra-53 [7]

2H₂ + O₂ ⇒ 2H₂O

<h3>Further explanation</h3>

Conservation of mass states that

<em>In a closed system, the masses before and after the reaction are the same</em>

So it can be concluded

mass of the reactants = mass of the products

mass cannot be created or destroyed

The number of atoms involved in a reaction remains the same⇒ number of moles also the same
chemical equation in balanced form

So let's see which of the several options , which one has the same number of atoms on both sides of the equation

2H₂ + O₂ ⇒ 2H₂O

H ⇒ left 4, right 4

O ⇒ left 2, right 2

so the equation is in balance and represents the Law of Conservation of

Now they feel it is best to have you identify an unknown gas based on its properties. Suppose 0.508 g of a gas occupies a volume

pishuonlain [190]

Answer: Option (b) is the correct answer.

Explanation:

The given data is as follows.

mass = 0.508 g, Volume = 0.175 L

Temperature = (25 + 273) K = 298 K, P = 1 atm

As per the ideal gas law, PV = nRT.

where, n = no. of moles = $\frac{mass}{\text{molar mass}}$

Hence, putting all the given values into the ideal gas equation as follows.

PV = $\frac{mass}{\text{molar mass}} \times RT$

1 atm \times 0.175 L = $\frac{0.508 g}{\text{molar mass}} \times 0.0821 L atm/ K mol \times 298 K$

= 71.02 g

As the molar mass of a chlorine atom is 35.4 g/mol and it exists as a gas. So, molar mass of $Cl_{2}$ is 70.8 g/mol or 71 g/mol (approx).

Thus, we can conclude that the gas is most likely chlorine.
