Dowling paper also known as the “dao ling paper," was originally produced by the United States Dowling (Dowling), which is a kind of more advanced paper. The wood is the raw material of Dowling paper. According to the paper whether have luster or not, it is divided into rough dowling paper and smooth dowling paper. The formal name of Dowling paper is glazed paper or glazed printing paper, which is a special paper for glazed printing and also suitable for letterpress printing. Glazed printing paper is suitable for printing and making Monochrome or polychromatic book covers, more advanced text and the insert or pictures (such as various medical journals - China social medical journal), all kinds of colorful illustrated, map paper, Commercial paper or public welfare propaganda, color trademark and all kinds of packaging paper and so on. The glazed printing paper technology is complex, so the requirement of paper quality of printing paper is high. Glazed printing paper is made by  bleached chemical pulp, bamboo pulp, rag and straw pulp and it is also needed to add some padding (Talcum powder, clay,) and mucilage (chemical agent such as surface sizing agent ). It is made on   the long wire paper machine, and calender , finally form paper into storage.<span>

Which of the following acids is the WEAKEST? The acid is followed by its Ka value.HF, 3.5 × 10^-4HNO2, 4.6 × 10^-4HCN, 4.9 × 10^
Mila [183]

Answer:

HCN

Explanation:

There are several factors that can tell us when an acid is stronger than another, which are the following:

1. The Polarity of the X - H Bond

2. Size of the X atom.

3. Charge on the acid.

4. Oxidation state of the central atom

5. Values of Ka and pKa.

From all of this factors, we can see that the exercise is already giving us values of Ka, and also we have different types of acid, not only with the form H - X

So, we will base the force of an acid by it's pKa value.

The pKa value which is calculated with the expression:

pKa = -logKa

pKa is a value that indicates how strong is the acid you are working with. This value can vary depending on factors such the charge of the acid. I f this charge can be easily distributed in resonance structures, the compound is more acidic, and therefore the pKa value is lower.

The lower the pKa, the more acidic the compound is.

So calculating the pKa on every structure we have:

HF: pKa = -log(3.5x10^-4) = 3.46

HNO2: pKa = -log(4.6x10^-4) = 3.34

HCN: pKa = -log(4.9x10^-10) = 9.31

HCOOH: pKa = -log(1.8x10^-4) = 3.74

HClO2: -log(1.1x10^-2) = 1.96

So according to all this values, we can conclude that the weakest acid is the HCN
