Chemistry

Answer:

The correct answer for the reverse reaction is the third option starting from top.

Explanation:

If we examine the given chemical equation:

2SO2 + O2 ⇌ 2SO3

The double arrow indicates that the reaction goes in both directions:

2SO2 + O2 -> 2SO3

2SO3 -> 2SO2 + O2

However, the closest option for the real situation would be the product from the semirreaction reacting in turn with oxygen:

2SO3 + O2 -> 2SO2

Thus, the correct answer is the third.

Answer:

2SO3 -> 2SO2 + O2 (not shown in the options)

Explanation:

In a reversible reaction, reactants react to produce products and products react to produce reactants, simultaneously.

Given the reversible reaction:

2SO2 + O2 ⇌ 2SO3

It has a forward reaction:

2SO2 + O2 -> 2SO3

and a reverse reaction:

2SO2 + O2 <- 2SO3

Calculate the average atomic mass of a
Vesna [10]

Answer: 207.217 amu

Work:

203.973 amu *(0.014) = 2.855 amu

205.974 amu *(0.241) = 49.639 amu

206.976 amu *(0.221) = 45.741 amu

207.977 amu *(0.524) = 108.979 amu

2.855 + 49.639 + 45.741 + 108.979 = <em><u>207.217amu</u></em>

How do the numbers of metal and non-metal elements compare? Estimate an approximate percentage difference.
Lerok [7]

Answer:

metal to non metal ratio is 97/21 = 4.62 or

82.2% metals, 17.8% non metals

Explanation:

How do the numbers of metal and non-metal elements compare? Estimate an approximate percentage difference. (learning about the periodic table if...

of 118 elements in the periodic table , 21 are non metals (even H has metallic properties when approching 0 degrees K)

this means there ar 21 nonmetals and 118-21=97 metals.

The possible products of a double displacement reaction in aqueous solution are SrSO4 and NaCl. Which of these possible products
madam [21]

Answer:

SrSO4

Explanation:

According to solubility rules, we know that the sulphates of the elements of group two are insoluble in water. The solubility rules describe what chemical species are soluble in water and what species are not soluble in water.

Generally, all chlorides are soluble in water with exception of chlorides such as silver chloride. The chlorides of group one elements are usually highly soluble in water.

Since SrSO4 is a sulphate of a group two element (strontium) it will be the insoluble solid product of the double displacement reaction described in the question.
