Explanation:

yea Mami you know like for real I feel you you know iam seeing but tomorrow I see the equation for the last works positive AAAAA

The largest amount of CO₂ produced when 2 moles of C₂H₂ reacted with 1 mole of O₂ is 0.8 mole

We'll begin by writing the balanced equation for the reaction. This is given below:

       2C₂H₂ + 5O₂ —> 4CO₂ + 2H₂O

            2     :   5

            2     :   1    

From the balanced equation above,

We can see that O₂ is the limiting reactant as lesser amount of it is available.

Finally, we shall determine the largest amount of CO₂ produced by using the limiting reactant as illustrated below:

From the balanced equation above,

5 moles of O₂ reacted to produce 4 moles of CO₂.

Therefore,

1 mole of O₂ will react to produce = 4/5 = 0.8 mole of CO₂.

Thus, the largest amount of CO₂ produced from the reaction is 0.8 mole

Your answer→ The lighter side absorbs less of the incident light, reflecting some of the energy. Darker materials also emit radiation more readily than light-colored materials, so they cool faster.

To solve this we must be knowing each and every concept related to radiation. Therefore, dark surfaces absorb radiation better than light surfaces as dark surfaces absorbs light of all wavelengths.

According to the energy of the emitted particles, radiation is frequently classified as being either ionizing or non-ionizing. More than 10 eV is often carried by ionizing radiation, which is sufficient to ionize atoms as well as molecules and rupture chemical bonds.

The word refers to radiation having an energy level high enough to ionize atoms, or to remove electrons from atoms to produce ions. Whenever an electron is removed from an atom's electron shell, or, as we may say, when it is "tried to knock out," the action of ionization takes place. Dark surfaces absorb radiation better than light surfaces as dark surfaces absorbs light of all wavelengths.

Therefore, dark surfaces absorb radiation better than light surfaces as dark surfaces absorbs light of all wavelengths.

Answer:

5.9405*10^14 Hz

Explanation:

Remember the equation c=v*λ

v=frequency

λ=wavelength

By manipulating the equation, we can get it in terms of frequency:

c/λ=v

Now convert wavelength to meters (1nm=m*10^-9)

5.05*10^-7m (2 decimal places were shifted to make the number between 1-10, hence the -7 exponent)

Use the manipulated equation:

(3.00*10^8)/(5.05*10^-7), which yields:

5.9405*10^14 Hz (or s^-1)

The frequency of the photon will be "[tex]5.9405\times 10^{14} \ Hz[/tex]".

According to the question,

Wavelength,

or,

          [tex]= 5.05\times 10^{-7} \ m[/tex]

As we know the equation,

→ [tex]c = v\times \lambda[/tex]

or,

→ [tex]v = \frac{c}{\lambda}[/tex]

By putting the values, we get

     [tex]= \frac{3.00\times 10^8}{5.05\times 10^{-7}}[/tex]

     [tex]= 5.9405\times 10^{14} \ Hz[/tex]

Volume

Explanation:

Volume is how much of a substance something can hold!

Hope this helped, have a nice day! :)

The word that completes the sentence is "volume."The volume of a bottle refers to how much liquid it can hold, typically measured in liters or milliliters.

Knowing the volume of a bottle is important when you need to measure out or store a certain amount of liquid. Different types of bottles have different capacities, so it's important to check the label or specifications to determine the right size for your needs.

Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units (such as the gallon, quart, cubic inch). The definition of length (cubed) is interrelated with volume. The volume of a container is generally understood to be the capacity of the container; i.e., the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces.

Thus, the word that completes the sentence is "volume."

Answer:

Transmutation is the conversion of an atom of one element into an atom of a different element through nuclear changes.

An alpha particle is a particle composed of 2 protons and 3 neutrons. It results from transmutation because of the change in protons in a large nucleus.

A chemical equation is balanced accord to the number of atoms of each element before and after the change. This is also shows the Law of Conservation of Matter.

A nuclear equation is balanced according to mass number and charge (atomic number). These equations can’t be balanced like chemical equations because the identities of the atoms can change.  On the left of equation, the top number is the atomic mass and the bottom number is the atomic number. Take note that if you add the atomic mass (top number), you’ll get the the atomic mass of of the atom pre-transmutation. Same applies with atomic number. This shows a balanced nuclear equation.

The atomic number is the number of protons in a nucleus. The mass number is the sum of the protons and neutrons in a nucleus. Electrons have very small masses, so they are not accounted in atomic mass.

Answer:

density=20/8 g/cc=2.5 g/cc

Mercury is more dense, so aluminum will float on it. Water is less dense, so the aluminum will be below water.

Aluminum will float atop mercury because it is more dense than it. Due to water's lower density, the metal will lie below the surface.

Density is defined as the measure of how densely a material is packed together.

It can also be defined as the mass of a solid substance per unit volume.

Density is important because it enables us to predict which compounds will float and which will sink in a liquid, density is a crucial notion. As long as an object's density is lower than the liquid's density, it will often float.

The term "density" refers to the relationship between a substance's mass and the volume it takes up in space. The mass, size, and arrangement of an object's atoms influence its density.

Density can be expressed as

Density = mass / volume

There are two types of density.

Thus, aluminum will float atop mercury because it is more dense than it. Due to water's lower density, the metal will lie below the surface.
