1/5 is the dilution of reagent A in water.

Explanation:

       [tex]D.F.=\frac{V_f}{V_i}[/tex]

       Where:

                 D.F = Dilution factor

                 [tex]V_f[/tex] = Final volume of the diluted solution

                 [tex]V_i[/tex]= Initial volume of the undiluted solution

Given:

4 parts of the reagent and 16 parts of water are mixed together to form a diluted solution.

To find:

The dilution of reagent A in water

Solution:

Parts of reagent A =[tex]V_i = 4[/tex]

Parts of water = 16

Final volume of solution = [tex]V _f = 4 + 16 = 20[/tex]

The dilution factor of reagent A:

[tex]D.F=\frac{20}{4}=5[/tex]

The dilution of the reagent A = [tex]1:5=\frac{1}{5}[/tex]

1/5 is the dilution of reagent A in water

Answer:

m=104000

Explanation:

by 1km=1000m

104km=?

Now

104km=104×1000m

=104000m

Therefore,m=104000 ans

104 kilometers is equal to 104,000 meters.

A conversion factor is a ratio that shows how two different units of measurement relate to each other. You can convert a value from one unit to another by multiplying or dividing the original value by a conversion factor.

For example,

Since there are 1000 meters in a kilometer, we need to multiply the distance in kilometers by 1000 to convert it into meters.

So, to convert 104 kilometers to meters:

104 Km * 1000 = 104,000 meters

Therefore, 104 kilometers is equal to 104,000 meters.

is the correct answer

_______________________________________________________

Answer:

_______________________________________________________

"Why?"

For instance, fluorine is the most reactive non-metal element on the periodic table. Due to it's small size, as well as it's strong electronegativity, fluorine has a strong tendency to accept electrons from other atoms and ions. But when Fluorine comes in contact with Hydrogen (a single valence electron element), for instance, it immediately reacts, resulting in an explosion.

Answer:

Both particles A and B

Explanation:

A nucleus contains both protons and neutrons .

But protons are positively charged whereas neutrons have no charge.

[tex].[/tex]

Both particles A and B are most likely present inside the nucleus of the atom. Therefore, option (c) is correct.

The nucleus of an atom contains the particles protons and neutrons. Both the solid particles in an atom are responsible for 99.9% of the mass in the nucleus.

The protons are the positively charged particles that lie inside the nucleus. Therefore, the nucleus of an atom has a positive charge on it while the negatively charged electrons rotate around the nucleus.

The neutrons do not carry any charge. So we can say that the neutrons are neutral. Therefore, the charge on the nucleus is only due to protons.

The atomic powers which are holding the protons and the neutrons inside the nucleus are also vast. The protons are prsent very close to each other inside the tiny nucleus, so the electrostatic forces of repulsion act in the nucleus.

Therefore, particles with no charge and positive charge are most present in the nucleus of the atom.

2) See below.

Explanation:

1) The warmer water vapour from the surroundings came into contact with the cooler inner surface of the glass jar and condensed, forming the water droplets (water vapour) on the inside of the glass jar.

2) As condensation occurs, condensed water vapour will drip into the water solution in the glass jar, causing the water to rise in the glass jar.

Answer:

Melting is an example of physical change.

Explanation:

Answer:

Relative dating is based on the positions of fossils in rock layers. Lower layers were laid down earlier, so they are assumed to contain older fossils. This gives the fossil an approximate age in years. Absolute dating is often based on the amount of carbon-14 or other radioactive element that remains in a fossil up until extinction.

Relative dating is a method of dating where the geologic events are arranged and the rocks are left behind in a sequence. They function on the basis of the stratigraphy and don't provide us with actual numeric data.

A photon is an elementary particle that has zero invariant mass and travels in a vacuum with a constant velocity. It is capable of generating electromagnetic phenomena since it carries all forms of electromagnetic radiation:

The photon presents wave and corpuscular properties, this means that it behaves as a wave in certain phenomena, such as refraction in a lens; and as a particle when it interacts with matter to transfer energy. The latter is expressed as follows:

[tex]E=\frac{hc}{lambda} = hv[/tex]

This means that each photon has energy that is proportional to the frequency of light.  In this case, the energy is quantized, which means that the energy of the photons is restricted to certain values. The energy at subatomic levels occurs in packets that refer to the photon, which are the packages of energy and each one correspond to different types of radiation.

This differs from classical waves, which can gain or lose arbitrary amounts of energy.

If we apply the equation and replace the information, we have:

[tex]E=\frac{6.63 x 10^{-34} J/s x 3 x 10^{8} m/s }{498 nm} = 3.99 x 10^{-28} J[/tex]

So 3.99 x 10^-28 J is the amount of energy of the photon of 498 nm emmited from a silicon atom.

Now we will show that the atomic levels are quantized. An atom has ground state (n=1) energy of 13.6 eV. Higher states means the atom is at an excited state. When this happens, an electron from an atom loses energy and makes a transition to a lower state. To avoid this and conserve energy, the atom emits a photon with an amount of energy that equals the difference of energy between a ground state and another state. So we can calculate the energy of the electron in different states.

[tex]E_{n} = \frac{-13.6 ev}{n^{2} }[/tex]

[tex]E_{1} = \frac{-13.6 ev}{1^{2} }=-13.6 ev[/tex]

[tex]E_{2} = \frac{-13.6 ev}{2^{2} }=-3.4 ev[/tex]

[tex]E_{3} = \frac{-13.6 ev}{3^{2} }=-1.511 ev[/tex]

N represents the principal quantum number, which is the overall energy of each orbital. This energy increases as its distance from the nucleus increases. Here we can se that the value of energy of n=1 is higher than energy of n=2, and this one is higher from the energy of n=3. This means each level has a specific energy and it is quantized according to the value of n.

So, a photon is an elementary particle which carries radiation and presents a wave-corpuscle duality, where particles may exhibit wave-like behavior in some experiments while appearing as particles in others. A photon is emmited when an atom loses energy, to conserve this energy and avoid a transition to a lower state.  The electron energy is quantized because it is restricted to characteristic values, only taking non-continuous values. In this question, the amount of energy of the photon emmited is 3.99 x 10^-28 J. And the atomic levels are quantized according to the principal quantum number.
