Answers

Answer:

D dark colors absorb the sun more cause the wants to make everything bright I hope I helped :)

The statement " Darker colors absorb more energy from electromagnetic waves than lighter colors do." is correct.

What is electromagnetic waves?

When an electric field collides with a magnetic field, electromagnetic waves are created. As a result, they're called electromagnetic waves.

What is light?

Light, often known as visible light, is electromagnetic radiation that falls within the region of electromagnetic wave or spectrum that the human eye can perceive.

White is a mixture of all seven colors found in the white light spectrum, including Violet, Indigo, Blue, Green, Yellow, Orange, and Red. This visible spectrum has a wavelength of 400 to 700 nanometers. When an object appears to be a particular color, such as red, it signifies that it is projecting the wavelength of red light  (620 to 750 nanometers) while absorbing all other wavelengths. Furthermore, because  light is a kind of energy, the more light a thing consumes, the more heat it consumes.

Which of the following does not apply to water molecules?

Water molecules are polar
Water has cohesive properties
Water is less dense as a solid than a liquid
Water is not a very good solvent

Answers

Answer:

It is the last one.

Explanation:

Water molecules are polar, they have cohesive properties, and water is less dense when it is solid than when it is a liquid, that is why ice floats in liquid water. However, water is a very good solvent, it can dissolve many solids, including sugar, salt, and other hydrophilic substances.

Las disoluciones comerciales de HCl (PF = 36.5 g/mol) típicamente son 39.0% P/P de este ácido en agua. Determine la molalidad de la disolución del HCl si la densidad de la misma es igual a 1.20 g/ml.

Answers

The translation of the question is

Commercial solutions of HCl (MP = 36.5 g / mol) are typically 39.0% W / W of this acid in water. Determine the molality of the HCl solution if its density is equal to 1.20 g / ml.

Answer:

Molality is 17.51 molal

Explanation:

We are given 39% w/w of HCl, this means for every 100g of this solution we have 39g of HCl in it.

to ease the calculation we assume we have 1L(1000ml) of this solution is present.

Density = mass /volume

1.20 = mass/1000

mass = 1200 g of solution

and we are given that 39% of this solution is will contain HCl

so

1200 * 39/100 = 468g of HCl present

no of moles of HCl = 468/36.5 = 12.82moles

mass of solution = mass of water + mass of acid

mass of water = mass of solution - mass of acid

Mass of water = 1200 - 468 = 732g of water

Molality = moles /masss of water in kg

             = 12.82 *1000/732  =17.51molal

When naming acids the prefix hydro- is used when the name of the acid anion ends in___

Answers

Answer:

hydrochloric acid

Explanation:

These anions usually have the ending “-ide.” As acids, these compounds are named starting with the prefix “hydro-,” then adding the first syllable of the anion, then the suffix “-ic.” For example, HCl, which is hydrogen and chlorine, is called hydrochloric acid. More complex acids have oxygen in the compound.

One isotope of oxygen differs from another isotope of oxygen in *

Answers

Each isotope of Oxygen has a different number of neutrons

Further explanation

The elements in nature have several types of isotopes

Atomic mass is the average atomic mass of all its isotopes

Isotopes are atoms has the same number of protons but has a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

Some of the isotopes of oxygen are:

[tex]\tt _8^{16}O,_8^{17}O,_8^{18}O[/tex]

Each isotope has 8 protons and 8 electrons but has a different number of neutrons

For O-16: number of neutrons = 16-8 = 8

For O-17: number of neutrons = 17-8 = 9

For O-18: number of neutrons = 18-8 = 10

Green light has a frequency of 6.01x10^14Hz what is the wavelength

Answers

Answer:

λ  = 0.5×10⁻⁶ m

Explanation:

Given data:

Frequency of light = 6.01 ×10¹⁴ Hz

Wavelength of light = ?

Solution:

Formula:

Speed of light = wavelength × frequency

Speed of light = 3×10⁸ m/s

3×10⁸ m/s = λ × 6.01 ×10¹⁴ Hz

λ  = 3×10⁸ m/s / 6.01 ×10¹⁴ Hz
