Answer:

[SO_2Cl_2] = 0.09983 M

Explanation:

Write the balance chemical equation ,

SO_2Cl_2((g) = SO_2(g) + Cl_2(g)

initial concenration of SO_2Cl_2((g)  =0.1M

lets assume that degree of dissociation=\alpha

concenration of each component at equilibrium:

[SO_2Cl_2] = 0.1-0.1\alpha

[SO_2] = 0.1\alpha

[Cl_2] = 0.1\alpha

Kc =\frac{0.1\alpha \times 0.1\alpha}{0.1-0.1\alpha}

Kc =\frac{0.1\alpha \times \alpha}{1-\alpha}

as \alpha is very small then we can neglect  1-\alpha

therefore ,

Kc ={0.1\alpha \times \alpha}

\alpha =\sqrt{\frac{Kc}{0.1}}

\alpha = 1.73 \times 10^{-3}

Eqilibrium concenration of [SO_2Cl_2] = 0.1-0.1\alpha = 0.1-0.1\times 0.00173

[SO_2Cl_2] = 0.09983 M

How would you prepare a 1 L solution of 3 M MgO?
oksano4ka [1.4K]

Answer:  175.35g

Explanation:  A 3 M solution has 3 moles of solute per litre.

The mass of one mole of NaCl equals the MW of NaCl MW =  35.45 + 23 =58.45 g/mol

The mass of 3 moles is 58.45 g/mol ×3 mol=175.35 g NaCl  or  200 g rounded to one sigfig.

Which subatomic particles had negligible mass and travels around outside the nucleus? A protons B neutron C electron D orbital ?
kap26 [50]
C. Electron. It’s a negatively charged particle that orbits around the nucleus. Usually, there are multiple electrons going around the nucleus in different orbitals (the circle around the nucleus in which the electron travels). The mass is much smaller compared to that of a proton or neutron and can be ignored when calculating the mass of an atom.

7. Interpret Data A company plans to make an electronic device. They need to use an element that has chemical behavior similar t
Goryan [66]

Germanium (Ge) is an element that has chemical behavior similar to that of silicon (Si) and lead (Pb). As it has an atomic mass greater than that of sulfur (S), but less than that of cadmium (Cd).

<h3>Why does the element of the same group have similar chemical behavior?</h3>

The chemical behavior of elements depends on the number of valence electrons in their outermost shell. Elements placed in the same group have the same number of valence electrons. Therefore, elements placed in the same group of the periodic table have similar chemical properties.

The elements having a similar outer electronic configuration in their atoms are arranged in the same group of the periodic table. These valence electrons are responsible chemical properties and reactivities of the elements.

Therefore, silicon and lead can be replaced by any element belonging to the same group in which Si and Pb are present. So we have germanium and tin. But germanium is the element that has an atomic mass greater than sulfur (S), but less than cadmium (Cd).
