Answer:

26.9L of SO2

Explanation:

The reaction between Sulphur and oxygen is as follows:

[tex]S_2 + 2O_2 \to 2SO_2[/tex]

This implies that:

2 moles of oxygen reacts with 1 mole of sulphur to produce 2 moles of SO₂

2 moles of oxygen also yields 2 moles of SO₂

The number of moles of oxygen given is determined as:

[tex]= 26.9 \ L \ of \ O _2 \times (\dfrac{1 \ mol \ of O_2 }{22.4 \ L}) \\\\ = 1.20 \ mol \ of \ O_2[/tex]

The number of moles of SO₂ by using the ratio is:

[tex]= 1.20 \ mol \ of \ O_2 \times (\dfrac{1 \ mol \ of \ SO_2 }{1 \ mol \ O_2}) \\ \\ = 1.20 \ mol \ of SO_2[/tex]

Finally, the volume by applying the new moles is computed as:

[tex]= 1.20 \ moles \ of \ O_2 \times ( \dfrac{1 \ mo \ of \ SO_2}{1 \ mol \ of O_2}) \times ( \dfrac{22.4 }{1 \ mol }) \\ \\ = 26.9 \ L \ of \ SO_2[/tex]

Transition metal ions tends to absorb light in the visible range.

Transition metal is defined as an element having a d subshell that is partially filled with electrons, or an element that has the ability to form stable cations with an incompletely filled d orbital.

The transition metals are located towards the middle of the periodic table between the highly reactive metals and the noble gases.

They are the only elements that may use electrons in the next to highest—as well as the highest—energy level as valence electrons.

Transition metals are unusual in having very similar properties even with different numbers of valence electrons.

Therefore, Transition metal ions tends to absorb light in the visible range.

Answer:

See Explanation

Explanation:

Metallic bonds involve attraction between electrons and positively charged metal ions. The metals are ionized and electrons form a sea of valence electrons. These loosely bound electrons surround the nuclei of the metals.

The presence of this sea of electrons explains the fact that metals conduct electricity and heat due to the free valence electrons.

Due to the nature of the bonding between metal atoms,metals are malleable and ductile.

Due to the strong electrostatic interaction between metal ions and electrons, the metallic bond is very strong and is very difficult to break thereby accounting for the greater strength of metals as the size of the metallic ion decreases.

Remark

Interesting que8stion. You have to figure out how many mols are present in each reactant. Since all periodic tables are different, I'm going to use rounded numbers. If it is too close, I will go further.

NaCl

Na = 23

Cl = 35.5

1 mol = 58.5 grams

given = 50.0 grams

Mols for the reaction = 50/58.5 = 0.855

H2SO4

H2       =    2*1        2

S          =   1 * 32   32

O4       =   4*16     64

1 mol  =               98   grams

mols  present = 50/98 = 0.510

MnO2

Mn     = 1 * 55    = 55

O2   =   2*16      = 32

1 mol =                  87 grams

mols available    = 50/87 = 0.5747

Discussion

Na Cl and H2SO4 both require 2 moles for every mol of Cl2 produces.

H2SO4  has 0.51 mols available for a reaction

NaCl has  0.855 moles available for a reaction

MnO2 has 0.575 moles available for a reaction.

Given those numbers 0.510 mols of H2SO4 will only produce 0.255 mols of chlorine and the rest will be reduced in a similar manner. H2SO4 is the limiting reagent (reactant).

In other words only 0.510 moles of NaCl will be used and 0.855 - 0.510 moles will be left over on the reactants side.

only 0.575 moles of MnO2 will be used and 0.065 moles will be left over.

The oddity in the result shows up because the balance numbers in the equation give a ratio of 2 to 1 for H2SO4 and NaCl The 2 belongs to the reactants and the 1 for the chlorine.

Answer:

melting point, 119.8 K, 0.72 atm, supercritical fluid, solid, gas, liquid.

Explanation:

Let's refer to the phase diagram (not to scale) for krypton.

At a pressure of 1 atm, the temperature 115.9 K is called the melting point of Kr, and it is the temperature at which it passes from solid to liquid.

The normal boiling point for Kr is at 119.8 K, which is, at 1 atm, the limit between the liquid and the gas state.

The triple point pressure for Kr is 0.72 atm, as can be seen in point C.

The critical pressure for Kr is 54.3 atm.

At temperatures above 209.4 K and pressures above 54.3 atm, Kr is a supercritical fluid, according to the region it is in the phase diagram.

Kr is a solid at 50.3 atm and 105 K, according to the region it is in the phase diagram.

Kr is a gas at 0.720 atm and 131 K, according to the region it is in the phase diagram.

Kr is a liquid at 1.00 atm and 118 K, according to the region it is in the phase diagram.

Answer:

[tex]28.037\ \text{s}[/tex]

Explanation:

[tex][A]_0[/tex] = Initial concentration = 1.28 M

[tex][A][/tex] = Final concentration = [tex]0.17[A]_0[/tex]

k = Rate constant = 0.0632 s

t = Time taken

For first order reaction we have the relation

[tex]kt=\ln\dfrac{[A]_0}{[A]}\\\Rightarrow t=\dfrac{\ln\dfrac{[A]_0}{[A]}}{k}\\\Rightarrow t=\dfrac{\ln\dfrac{[A]_0}{0.17[A]_0}}{0.0632}\\\Rightarrow t=28.037\ \text{s}[/tex]

Time taken to reach the required concentration would be [tex]28.037\ \text{s}[/tex].

I believe the answer is 18.

Answer:

Explanation:

From the given information:

The energy of photons can be determined by using the formula:

[tex]E = \dfrac{hc}{\lambda}[/tex]

where;

planck's constant (h) = [tex]6.63 \times 10^ {-34}[/tex]

speed oflight (c) = [tex]3.0 \times 10^8 \ m/s[/tex]

wavelength λ = 58.4 nm

[tex]E = \dfrac{6.63 \times 10^{-34} \ J.s \times 3.0 \times 10^8 \ m/s}{58.4 \times 10^{-9 } \ m}[/tex]

[tex]E =0.34 \times 10^{-17} \ J[/tex]

[tex]E = 3.40 \times 10^{-18 } \ J[/tex]

To convert the energy of photon to (eV), we have:

[tex]1 eV = 1.602 \times 10^{-19} \ J[/tex]

Hence

[tex]3.40 \times 10^{-18 } \ J = \dfrac{1 eV}{1.602 \times 10^{-19 } \ J }\times 3.40 \times 10^{-18 } \ J[/tex]

[tex]E = 2.12 \times 10 \ eV[/tex]

E = 21.2 eV

b)

The equation that illustrates the process relating to the first ionization is:

[tex]Hg_{(g)} \to Hg^+ _{(g)} + e^-[/tex]

c)

The 1st ionization energy (I.E) of Hg can be calculated as follows:

Recall that:

I.E  = Initial energy - Kinetic Energy

I₁ (eV) = 21.2 eV - 10.75 eV

I₁ (eV) = 10.45 eV

Since ;

[tex]1 eV = 1.602 \times 10^{-19} \ J[/tex]

∴

[tex]10.45 \ eV = \dfrac{1.602 \times 10^{-19 } \ J }{ 1 \ eV}\times 10.45 \ eV[/tex]

Hence; the 1st ionization energy of Hg atom = [tex]1.67 \times 10^{-18} \ J[/tex]

[tex]1.67 \times 10^{-21} \ kJ[/tex]

Finally;

[tex]I_1 \ of \ the \ Hg (kJ/mol) = \dfrac{1.67 \times 10^{-21 \ kJ} \times 6.02 \times 10^{23} \ Hg \ atom }{1 \ Kg \ atom }[/tex]

[tex]\mathbf{= 1.005 \times 10^3 \ kJ/mol}[/tex]

Answer: The pH of solution is 10.

The pOH of the solution is 4.

Explanation:

pH is the negative logarithm of concentration of hydrogen ion.

As given concentration of acidic solution is [tex]1.00 \times 10^{-10} M[/tex]. Therefore, pH of the solution is calculated as follows.

[tex]pH = -log [H^{+}]\\= -log (1.00 \times 10^{-10})\\= 10[/tex]

The relation between pH and pOH is as follows.

pH + pOH = 14

pOH = 14 - pH

= 14 - 10

= 4

Thus, we an conclude that pH of solution is 10 and pOH of the solution is 4.
