Classify the following reaction according to the five basic reaction types:

Cd(s)+H2SO4(aq)→CdSO4(aq)+H2(g)

a. single replacement
b. combustion
c. double replacement
d. combination(Synthesis)

a. single replacement

Explanation:

Chemical equation:

Cd + H₂SO₄    →    CdSO₄ + H₂

In given reaction Cd replace the hydrogen and form cadmium sulfate and hydrogen gas.

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

Other options are incorrect because,

Combustion:

In combustion reaction substances are burn in the presence of oxygen and form carbon dioxide and water.

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

A + B  →  AB

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AC +BD

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
