Accordingly, the majority of the bonds in the molecule, tin (ii) sulfide, are covalent, accounting for around 90% of the bonds. An extremely thin anode interlayer is used in organic photovoltaics by the compound tin(II) thiocyanate, Sn(SCN)2.
Stannic sulfide, tin disulfide, and tin bis(sulfanylidene) are examples. EC number: 215-252-9; CAS number: 1315-01-1. A chemical compound is tin(II) sulfate. SnSO4 is its atomic number. Tin and sulfate ions can be found in it. The chemical element tin has the atomic number 50 and the letter Sn for its symbol. At room temperature, tin is solid and is categorized as a post-transition metal. In order to create Tin dioxide and two molecules of hydrogen gas, Tin combines with two molecules of water, which are really in the form of steam. A reminder: Acids and alkalis corrode tin.

Answer:
0.0097 mol·L⁻¹
Explanation:
The balanced equation is
2NOCl ⇌ 2NO₂ + Cl₂
Data:
Your value of Kc is incorrect. It should be
Kc =1.6 × 10⁻⁵
[NOCl] = 0.50 mol·L⁻¹
[NO] = 0.00 mol·L⁻¹
[Cl₂] = 0.00 mol·L⁻¹
Calculations:
1. Set up an ICE table.
2. Calculate the equilibrium concentrations
This is a cubic equation. Some calculators can solve cubic equations, but we can solve it by the method of successive approximations.
We will make changes to the right-hand side until the calculated value of x no longer changes,
(a) 1st approximation
Assume that 2x is negligible compared to 0.50. Then
(b) 2nd approximation
Assume that x= 0.010. Then
(b) 3rd approximation
Assume that x= 0.0097. Then
No change, so x = 0.0097.
[Cl₂] = x mol·L⁻¹ = 0.0097 mol·L⁻¹

It checks.
cu=1*63g=63g
n=2*14g=28g
o=6*16g=96g
total=187g/mol
122(1 mol/187)(6.02*10^23)= 3.92*10^23
Answer:
B.
Explanation:
When water separates into hydrogen and oxygen gas, a decomposition reaction is taking place (one substance breaking apart or breaking down into two or more substances).
The law of conservation of mass tells us that mass is not created or destroyed during a chemical reaction, so the total mass will remain the same. This is supported by the diagram on the page, which shows that in the reactants, there are four hydrogen atoms and two oxygen atoms, and this amount is the same on the product side.
