What is IUPAC Nomenclature?

The IUPAC system of nomenclature is a set of logical rules framed which are mainly aimed at giving an unambiguous name to an organic compound.

IUPAC stands for International Union of Pure and Applied Chemistry

A prefix to the name comes before the molecule. The prefix of the molecule's name is based on the number of carbon atoms.

For example, a chain of six carbon atoms would be named using the prefix hex-.

The suffix to the name is an ending that is applied that describes the types of chemical bonds in the molecule.

The molecule has 6 carbon atoms and a methyl group at the second position.

Therefore, The molecule is 2-methylhexane and the correct option is option B.

Which of the following is an example
of a chemical property?
A. Iron has a tendency to rust.
B. The boiling point of water is 100°C.
C. Salt will dissolve in water.
D. Chlorine does not conduct
electricity

Answers

Answer:

Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.

A is the answer because when iron rusts, the iron atoms combine with oxygen atoms to form a different chemical substance. Rusting is therefore a chemical change and the tendency of iron to rust is a chemical property

Explanation:

If 348 grams of Mg(OH)2 reacts with excess HCl (this is CL chlorine, not C and I), how many moles of MgCl2 (this is CL chlorine, not C and I) are produced?

Answers

Answer:

moles MgCl₂ = 5.97 moles

Explanation:

First, let0s write the overall reaction that is taking place here:

Mg(OH)₂ + HCl ----------> MgCl₂ + H₂O

Now, we need to balance this reaction:

Mg(OH)₂ + 2HCl ----------> MgCl₂ + 2H₂O

Now, the exercise already stated that the HCl is in excess, so we can assume the magnesium hydroxide is the limiting reactant. If this is true, then, to get the moles of MgCl₂ produced, all we need to do is calculate the moles of Mg(OH)₂ that reacted, using the following expression:

moles = mass / MM

The atomic weights for Mg, O and H are:

Mg: 24.305 g/mol;  H: 1 g/mol;  O = 15.999 g/mol

Let's determine the molar mass of Mg(OH)₂:

MM = 24.305 + (2 * 15.999) + (2 * 1) = 58.303 g/mol

Now, let's determine the moles:

moles = 348 g / 58.303 g/mol = 5.97 moles of Mg(OH)₂

As we can see in the overall reaction, there is a mole ration between Mg(OH)₂ and MgCl₂ of 1:1, that's why we can conclude that the moles of Mg(OH)₂ would be the same moles of MgCl₂:

moles Mg(OH)₂ = moles MgCl₂ = 5.97 moles

Hope this helps

Answers

A dry cell is one type of electric battery which is generally used for the home and portable electronic devices. A battery is a device which consists of one or more electrochemical cells. The site of oxidation occurs in solid zinc layer. The correct option is A.

What is a dry cell?

A dry cell is defined as an electrochemical cell which consists of low moisture immobilized electrolytes in the form of a paste which restricts it from flowing. It is developed by the German scientist Carl Gassner which converts chemical energy into electrical energy.

A dry cell consists of a metal container in which a low moisture electrolyte paste covers the graphite rod or a metal electrode. Generally, the metal container will be zinc whose base perform as the negative electrode (anode).

For a dry cell battery to operate, oxidation  will occur from the zinc anode and reduction will take place in the cathode.

Thus the correct option is A.

How many moles of nitrogen are required to produce 13.5 g of NH 3?

Answers

Answer:

number of moles of (N) = 0.794 moles

Explanation:

From the given information:

no of moles of nitrogen (N) = (unknown)???

mass of nitrogen = 13.5 g

molar mass of NH3 = 14 +( 1 × 3) = 17 g/mol

To calculate the no of moles of N, we have:

number of moles of (N) = mass of N/molar mass

number of moles of (N) = 13.5 g/17 g/mol

number of moles of (N) = 0.794 moles

How many liters of chlorine are needed to produce 5.64 moles of aluminum chloride? Need help ASAP

Answers

Answer:

190 L

Explanation:

Given that:

Number of moles = mass/molar mass

number of moles = 5.64

molar mass of aluminum chloride = 133.34 g/mol

The balanced equation is:

2 Al + 3 Cl2 --> 2AlCl3.

From above reaction:

5.64 mole of  AlCl3 reacts with 3 mole Cl2  to give 2 mole AlCl3

i.e

[tex](5.64 \ mole \ AlCl3) \times (3 \ mole \ Cl2 \ / \ 2 \ mole \ AlCl3)[/tex]

= 8.46 mole Cl2 gas.

At Standard temperature and pressure:

= (22.4 L/1 mole gas) * (8.46 mole Cl2)

= 190 L chlorine gas
