Can somebody explain step by step how to solve decomposition reactions?

SVEN [57.7K]

A decomposition reaction occurs when one reactant breaks down into two or more products. It can be represented by the general equation:

AB → A + B
In this equation, AB represents the reactant that begins the reaction, and A and B represent the products of the reaction. The arrow shows the direction in which the reaction occurs.

A 6.26 g sample of a solid containing ni is dissolved in 20.0 ml water. a 5.00 ml aliquot of this solution is diluted to 100.0 m

saveliy_v [14]

Concentration of Ni in 20mL = 5.28ppm x dilution factor = 5.28 x 100/5 = 105.6 ppm = 105.6 mg/L

molar mass of Ni = 58.6934 g
<span>Molarity of Ni = 100.40 x 10^{-3} / 58.6934 = 1.71 x 10^{-3} M = 1.71 mM. </span>

Carbon monoxide is 1. an atom, an element and a mixture. 2. a molecule, element and a pure substance. 3. an atom, a compound and

SSSSS [86.1K]

Answer:

The correct answer is option (6).

Explanation:

A molecule is group of atoms of same or different kinds of element.

In carbon monoxide there is a single carbon atom and single oxygen atom. Hence, a molecule.

Compound is defined as a chemical specie which is made by the combination of different atoms.

As we can see from the chemical formula of carbon monoxide is made up of two atom of different elements that is carbon and oxygen.

A pure substance is defined as the substance which is formed by same or different type of atoms which are chemically combined in a fixed ratio by mass. They have definite set of properties.

$C+\frac{1}{2}O_2\rightarrow CO$

1 mole of carbon combined with 0.5 moles of oxygen gas to give carbon monoxide gas.
