What is the particle unit for SO42-?

Chemistry
2 answers:
Helga [31]3 years ago
8 0

I believe that what is meant here to be particle unit is the elementary charge of the compound SO4^2-. In this case, the whole compound is raised to the power of 2-, therefore the elementary charge is 2-, this is the total electrons that the compound is carrying or sharing. These 2 electrons are being shared with 2 hydrogen atoms to form H2SO4.

Answer: The particle unit is an ion.

Explanation: The unit which is common used for the substances is Mole. 1 mole of anything equals to Avogadro number which is 6.022*10^2^3 .

For example, 1 mole of an electron equals to 6.022*10^2^3 electrons,

1 mole of an atom equals to 6.022*10^2^3 atoms.

So, 1 mole equals to 6.022*10^2^3 particles.

SO_4^-^2 is sulfate ion. So, the particle unit for this will be an ion.

If they were not repeatable people would think the experiment is not accurate. If it can be repeated than the data can prove a very valid point.

What is the wavelength (in nm) of
LenKa [72]

Answer:

λ = 0.45×10⁻⁶ m

Explanation:

Given data:

Wavelength of blue light = ?

Frequency of blue light = 6.69×10¹⁴ s⁻¹

Solution:

Formula;

Speed of wave = wavelength × frequency

Speed of wave = 3.00×10⁸ m/s

by putting vales,

3.00×10⁸ m/s = λ × 6.69×10¹⁴ s⁻¹

λ = 3.00×10⁸ m/s / 6.69×10¹⁴ s⁻¹

λ = 0.45×10⁻⁶ m

If the following weights have masses of 2, 4, 6 and 8 kg,
Marrrta [24]

Answer:

8 kg mass

Explanation:

As we can see in the image the weight of mass 8 kgs has a large surface area as compared to the surface area of other masses. In general, it has been observed that a wide surface area has more surface particle for heat conduction. Hence, the rate of heat transfer is directly proportional to the surface area of heat conducting surface. Thus, the larger the surface area, the faster is the rate of heat conduction.

Hence, weight of mass 8Kg wil transfer heat a fast rate.

Using the van der Waals equation, the pressure in a 22.4 L vessel containing 1.00 mol of neon gas at 100 °C is ________ atm. (a
svetoff [14.1K]

Answer:

The answer to your question is        P = 1.357 atm

Explanation:

Data

Volume = 22.4 L

1 mol

temperature = 100°C

a = 0.211 L² atm

b = 0.0171 L/mol

R = 0.082 atmL/mol°K

Convert temperature to °K

Temperature = 100 + 273

                      = 373°K

Formula

               (P + \frac{a}{v^{2}} )(v - b) = RT

Substitution

               (P + \frac{0.211}{22.4})(22.4 - 0.0171) = (0.082)(373)

Simplify

               (P + 0.0094)(22.3829) = 30.586

Solve for P

                           P + 0.0094 = \frac{30.586}{22.3829}

                           P + 0.0094 = 1.366

                                 P = 1.336 - 0.0094

                                P = 1.357 atm
