Answer: longer wavelength and lower energy.

Explanation:

1) The wavelength is inversely related to the frequency. So, an electromagnetic wave with lower frequency will have longer wavelength.

This is the formula for electromagnetic waves:

λ = c / ν

where λ is the wavelength, c is the speed of light, and ν is the frequency.

2) Energy is directly related to the frequency.

This is the formula E = hν,

where E is the energy, h is Planck constant, and ν is the frequency.

So, the lower the frequency the lower the energy.

3) Conclusion:
<span>An electromagnetic wave that has a lower frequency than infrared radiation will have longer wavelength and lower energy than the infrared radiation</span>

Two substances, A and Z, are to be identified. Substance A can not be broken down by a chemical change. Substance Z can be broke
Kisachek [45]

Answer;

(3) Substance A is an element and substance Z is a compound.

Explanation;

-A compound is a substance formed when two or more chemical elements are chemically bonded together, such as water, carbon dioxide, methane, etc while an element is a pure chemical substance made of same type of atoms, such includes, oxygen, potassium, hydrogen, carbon, etc.

- Compounds can be broken down or decomposed into simpler substances: elements cannot be broken down chemically into simpler substances .

GarryVolchara [31]

In light reactions there is successful photosynthesis due to the fact one of the primary reactants for photosynthesis in the first place. At the end of the light reaction, there will be the normal photosynthesis products formed which are glucose and oxygen. For the dark reaction no products will be formed

The vapor pressure of a substance is measured over a range of temperatures. A plot of the natural log of the vapor pressure vers
Gala2k [10]

Answer:

28.7664 kJ /mol

Explanation:

The expression for Clausius-Clapeyron Equation is shown below as:

\ln P = \dfrac{-\Delta{H_{vap}}}{RT} + c

Where,

P is the vapor pressure

ΔHvap  is the Enthalpy of Vaporization

R is the gas constant (8.314×10⁻³ kJ /mol K)

c is the constant.

The graph of ln P and 1/T gives a slope of - ΔHvap/ R and intercept of c.

Given :

Slope = -3.46×10³ K

So,

- ΔHvap/ R = -3.46×10³ K

<u>ΔHvap = 3.46×10³ K × 8.314×10⁻³ kJ /mol K = 28.7664 kJ /mol</u>

Which of the following changes would decrease the rate at which a solid solute dissolves in a liquid solvent?
andriy [413]

Answer:

Decreasing surface area of the solid in the liquid.

Explanation:

I don't know how to explain this without using. an example. So, here it is: If you were dipping bread in water, the bread would be completely soaked if you dipped the whole thing, but if you only allowed one part of the bread to be in the water, it would take longer for the water to soak all the way into it. The amount of surface area that is allowed to touch what is making the solid dissolve determines how quickly the whole thing will be dissolved.

ExtremeBDS [4]

Answer:

Lost pigment of marker when dipped in alcohol

Explanation:

dependent viable = output

so it's the output of what happens after the input.

  • she put the marker in the water which is the independent variable, that's the input
  • the output or the result of that decision is having lost pigment in the marker
