Answer:

The answer to your question is SO₂ + 3H₂ ⇒ H₂S + 2H₂O

Explanation:

Reaction

SO₂ + H₂ ⇒ H₂S + H₂O

Reactants Elements Products

1 Sulfur 1

2 Hydrogen 4

2 Oxygen 1

This reaction is unbalanced so we need to balance it.

SO₂ + 3H₂ ⇒ H₂S + 2H₂O

Reactants Elements Products

1 Sulfur 1

6 Hydrogen 6

2 Oxygen 2

Now, the reaction is balanced

Intermolecular forces allow which of the following substances to be the least fluid?

slava [35]

Out of the options, glass is the least fluid. The proof of this also lies in the fact that glass is the most difficult to melt out of all of the mentioned substances, and melting point gives us a rough estimate of the strength of intermolecular forces.

Calculate the percent by mass of water is Copper (II) Fluoride tetra hydrate. You must show all of your work to earn credit. Ato

lara [203]

Answer:

41.4%

Explanation:

The salt copper II fluoride tetrahydrate is a hydrated salt. A hydrated salt is a salt that has some molecules of water of crystalization attached to its structure. The formula of the salt is CuF2.4H2O

The first step is to calculate the molecular mass of the compound as follows

[64 + 2(19) + 4((2×1) + 16)] = [64 + 38 + 72]= 174gmol-1

Mass of water of crystallization= 4((2×1) + 16) = 72 g

Percentage by mass of water of crystallization= 72 / 174 ×100

Percentage by mass of water if crystalization = 41.4%

In a molecule of fluorine, the two shared electrons give each fluorine atom how many electron(s) in the outer energy level

timofeeve [1]

Answer:

8 electrons

Explanation:

As per the <u>octet rule</u>, the atoms possess a tendency to bond in a manner that every atom must have at least eight(8) electrons in its outermost/valence shell. It can be done either by sharing, gaining, or losing electrons from one atom to another. According to this rule, flourine would have 8 electrons in its outer shell after two shared electrons are given to it.

Each of the following names is wrong. Draw structures based on them, and correct the names:(b) 1,1,1-trimethylheptane

devlian [24]

The correct IUPAC name of 1,1,1-trimethylheptane is 2,2-dimethyloctane.

<h3>IUPAC NAME:</h3>

It is systematic way of nomenclature of organic compounds.

It is based on the position of functional groups, preference of the functional group, long or short chain of carbon, preference of double bond, single and triple bond, branching of carbon chain, etc.

The given compound is 1,1,1-trimethylheptane.

The given name is wrong according to IUPAC name because the numbering of carbon atom should be done in that way in which the carbon atom chain is largest.

Here, in this case the numbering is done from right side. Thus the largest carbon chain have 8 carbon atom.

If the numbering is done according to the question, number of carbon atom in straight chain is 7.

Thus, we concluded that the Correct IUPAC name of 1,1,1-trimethylheptane is 2,2-dimethyloctane.
