what is the cation and the anion of VCl3?
The cation is [tex]V^3^+[/tex] and the anion is [tex]Cl^-[/tex] in [tex]VCl_3[/tex].
An ionic compound is a chemical compound made up of charged ions called cations and anions that are held together by electrostatic forces.
Cations are elements with one or more positive charges because they have more number of protons than electrons.
Anions are elements with one or more negative charges because they have more number of electrons than protons.
An ion which has lost electrons and now has a positive net charge is said to be a cation. An atom's cation is smaller than the neutral atom because electrons are taken out to produce a cation.
An ion which has acquired electrons and now has a negative net charge is called an anion. The anion of an atom is larger than the neutral atom because electrons have been added to produce it.
In Vanadium (III) chloride, vanadium gives 3 electrons and become +3 charge and chlorine gains 1 electron and become -1 charge. Since 3 electrons are given by vanadium, 3 chlorine atoms are bonded, thus the compound is [tex]VCl_3[/tex].

I need these 3 questions answered with work shown :( I’m so bad at chem
Explanation:
3.)The given values:
Mass, m = 100.0 g
Density, d = 1.59 g/mL
As we know,
→ D = m/v
By substituting the given values, we get
v = m/d = 100/1.59
v = 62.89 ≈ 63mL
4.)The experiment makes use of Archimedes' principle, where the volume of a liquid displaced by an object, is equal to the volume of said object.
Thus, the volume displaced by the object is:
46.9 mL - 25.0 mL = 21.9 mL
The volume of the object is 18.9 mL
Density is equal to the mass divided by the volume, so:
D = m/V = 53.5 g/21.9 mL
D = 2.44 g/mL
5.)For water,
ρ density = 1.0 g/mL
v = 425 mL
d = m/v
m = d × v
m = 1 × 425 = 425 g
Which relationship is NOT correct?

O 1.6 J/gºC
The specific heat capacity of the metal rod weighing 123g is 0.14 J/gºC (option B).
How to calculate specific heat capacity?The specific heat capacity of a metal substance can be calculated using the following formula:
Q = mc∆T
Where;
Q = heat absorbed or releasedm = mass of substancec = specific heat capacity∆T = change in temperatureHowever, in a calorimeter, the metal and water relationship is given as follows:
Q (water) = - Q (metal)
mc∆T (water) = - mc∆T (metal)

4. Consider Limitations Students were given the following sets of items and asked, for each set, to identify which item had greater thermal energy. For which set would this task be most difficult? Explain. Set 1: 5 g of iron at 45°C and 10 g of iron at 45 °C Set 2: 10 g of water at 30°C and 10 g of water at 50°℃ Set 3: 32 g of copper at 50°C and 32 g of nickel at 50°C
Set 1 is difficult.
The formula for thermal energy is given as:
Q = mcΔT
Where m is the mass of the item, c is specific heat capacity and ΔT is the change in temperature when the item is heated.
For Set 1:
5 g of iron at 45°C and 10 g of iron at 45 °C
In this case, the mass of iron is different at the same temperature. Since there is no change in temperature hence the metal is not heated. Another reason is that the mass of iron is different in this case. Hence, this set will be difficult to find thermal energy.
Set 2:
10 g of water at 30°C and 10 g of water at 50° C
The mass of water at both temperatures is the same, and the water is heated from 30°C to 50° C The thermal energy can be easily calculated using the formula Q = mcΔT.
Set 3:
2 g of copper at 50°C and 32 g of nickel at 50°C
The mass of copper remains unchanged, also the temperature doesn't change. Since copper is not heated and the temperature remains constant. Hence the thermal energy will be zero.

While the air temperature drops underneath its dew factor, excess moisture can be released in the form of condensation. Condensation problems are maximumly probable to occur in climates in which temperatures regularly dip to 35°F or colder over a prolonged time period.
The dew factor is the temperature to which air needs to be cooled to emerge as saturated with water vapor, assuming steady air stress and water content. while cooled beneath the dew point, moisture potential is reduced and airborne water vapor will condense to form liquid water known as dew.

It takes a total of 56 days for the mass of the chromium-51 to be reduced from 12.0 μg to 3.00 μg.
What is the half life?The half life of a radioactive sample refers to the time taken for only half of the radioactive substance that is originally present to decay. Now we know that radioactivity has to do with the spontaneous disintegration of a substance. This implies that the amount of the substance would continue to decreases as the time goes on.
Having said this, let us consider the question as we have it above. We all know that; the half-life of radioactive chromium-51 is 28 days then the sample of chromium-51 has a mass of 12.0 μg. We are to now obtain the number of days it will take for the mass to be reduced to 3.00 μg .

Therefore, ΔT = T₂ - T₁ = 64.9 - 5.5 = 59.4° C
The heat energy is given as:
Q = m × C × ΔT
Q = (5.95 g ) × ( 4.2 J g⁻¹ C⁻¹ ) × ( 59.4° C )
Q = 1484.406 J
The energy released on heating 5.95 g of water from 5.5° C to 64.9° C is 1484.406 J.

Proton moving at 3.97 X 10 8 m/s (mass of a proton = 1.673 x 10 -27 kg) what is its wavelength in nm??
The wavelength of the proton is9.9 * 10⁻⁷ nm.
What is the wavelength of the proton?The wavelength of a particle or wave is the distance between successive point in phase in the particle or the wave.
It can be said to be distance between successive crests or troughs.
The wavelength of a moving particle is given by the De Broglie's equation as follows:
λ = h/mvwhere h is Planck's constant = 6.63×10⁻³⁴ Js
m = mass of particle = 1.673 x 10⁻²⁷ kg
v is velocity of proton = 3.97 x 10⁸ m/s
λ = 6.63×10⁻³⁴/1.673 x 10⁻²⁷ * 3.97 x 10⁸
λ = 9.9 * 10⁻⁷ nm

What qualities do you think are important for a scientist to have? Give an example of how one of these qualities is shown in your own approach to your schoolwork. Answer in two to three paragraphs. (10 points) Think about what a scientist does in order to obtain reliable information. Do you do any of these things?
Important qualities for scientists to have are curiosity, patience, creativity, persistence, communication, and intelligence.
Hard effort, intelligence, and the ability to effectively manage your time and tasks are, in my opinion, some crucial characteristics for a scientist to possess. Being a scientist will need you to spend a lot of time in a lab or out in nature. It takes skill to meticulously record vital and fascinating information. Additionally, you'll need to be diligent because it's crucial for scientists to put in a lot of effort and produce reliable results.
I believe that hard work is a quality that comes through in my academic performance. I always give my tasks my best effort. I make a consistent effort to get ahead and complete my task on schedule. I have to work less as I work harder. I keep myself busy, which causes me to become less busy.
