Choose the name of the compound formed by the ions Sn4+ and I1-

1 answer:

6 0

This question is providing two ions, Sn⁴⁺ and F¹⁻ so that the compound they form is asked to be named. At the end, according to the IUPAC rules, the name will be B: Tin (IV) fluoride.

<h3>Nomenclature:</h3>

In chemistry, nomenclature is used to assign the proper name of a chemical compound, so that it can be recognized in any part of the world. In this particular case, since this is a binary salt with a cation that has two oxidation states, Sn⁴⁺ and Sn²⁺, we should assign the correct roman numeral, which is tin (VI).

On the other hand, since fluorine takes a negative charge when forming binary salts, as a 1-, its assigned name would be fluoride. In such a way, by combining them, we find the name as B: Tin (IV) fluoride.

<h3>Further explanation</h3>

Given

1.72 moles of NOCI

1.16 moles of NOCI remained

2.50 L reaction chamber

Reaction

2NOCI(g) = 2NO(g) + Cl2(g).

Required

the equilibrium constant, Kc

Solution

ICE method

2NOCI(g) = 2NO(g) + Cl2(g).

I 1.72

C 0.56 0.56 0.28

E 1.16 0.56 0.28

Molarity at equilibrium :

NOCl :

$\tt \dfrac{1.16}{2.5}=0.464$

NO :

$\tt \dfrac{0.56}{2.5}=0.224$

Cl2 :

$\tt \dfrac{0.28}{2.5}=0.112$

$\tt Kc=\dfrac{[NO]^2[Cl_2]}{[NOCl]^2}\\\\Kc=\dfrac{0.224^2\times 0.112}{0.464^2}=0.026$

The periodic table is an important but rather dry scientific tool. It lists all the chemical elements, ordered by their atomic numbers. Elements with similar behavior are grouped in the same column (called a group), with metals generally on the left and non-metals (gases) on the right. Rows are called “periods” - hence, periodic table.

Is this what you looking for ???

Answer:

15g

Explanation:

The equation for the reaction is given below:

CaO + SO2 —> CaSO3

Molar Mass of CaO = 40 + 16 = 56g/mol

Molar Mass of CaSO3 = 40 + 32 + (16x3) = 40 + 32 + 48 = 120g/mol

From the equation,

56g of CaO produced 120g of CaSO3.

Therefore, 7g of CaO will produce = (7 x 120)/56 = 15g of CaSO3

Therefore, 15g of CaSO3 is produce
