Chemistry
1 answer:
kumpel [21]3 years ago
6 0

Answer:

Mass number is indicative of the number of protons and neutrons in the nucleus of Fez. The number of protons present in a neutral atom is equal to that of the number of electrons. Hence the number of neutrons present = 56- number of electrons.

Which direction does the decimal move from mega meters to meters
Temka [501]

To solve this problem, let us first understand what does mega meters mean. Now by definition, mega means a factor of one million which is a unit prefix in Metric Systems of units. It is denoted by the unit symbol M.

So for example if we have a mega of something, it means a million of something. So in this case, if we have 1 mega meter, what it means is 1 million meter, which is written as:

1 mega meter = 1,000,000 meter

 

To show the decimal points:

1.0 mega meter = 1,000,000.0 meter

 

So we see that the decimal point move 6 zeroes to the right, therefore the direction is to the right.

 

Answer:

<span>6 places to the right</span>

Predict the products of each of the following reactions and then balance the chemical equations.
Nookie1986 [14]

<u>Answer:</u> The chemical equations are given below.

<u>Explanation:</u>

  • <u>For a:</u> Fe is heated in an atmosphere of steam.

The chemical equation follows:

3Fe(s)+4H_2O(g)\rightarrow Fe_3O_4(s)+4H_2(g)

By Stoichiometry of the reaction:

3 moles of iron reacts with 4 moles of steam to produce 1 mole of iron (II,III) oxide and 4 moles of hydrogen.

  • <u>For b:</u> NaOH is added to a solution of Fe(NO_3)_3

The chemical equation follows:

Fe(NO_3)_3+3NaOH\rightarrow Fe(OH)_2+3NaNO_3

By Stoichiometry of the reaction:

1 mole of iron nitrate reacts with 3 moles of sodium hydroxide to produce 1 mole of iron hydroxide and 3 moles of sodium nitrate.

  • <u>For c:</u> FeSO_4 is added to an acidic solution of KMnO_4

The chemical equation follows:

10FeSO_4+2KMnO_4+8H_2SO_4\rightarrow 5Fe_2(SO_4)_3+K_2SO_4+2MnO_4+8H_2O

By Stoichiometry of the reaction:

10 moles of iron(II) sulfate reacts with 2 moles of potassium permangante and 8 moles of sulfuric acid to produce 5 moles of iron(III) sulfate, 1 mole of potassium sulfate, 2 moles of manganese oxide and 8 moles of water.

  • <u>For d:</u> Fe is added to a dilute solution of H_2SO_4

The chemical equation follows:

Fe+H_2SO_4\rightarrow FeSO_4+H_2

By Stoichiometry of the reaction:

1 mole of iron reacts with 1 mole of sulfuric acid to produce 1 mole of iron sulfate and 1 mole of hydrogen gas.

  • <u>For e:</u> A solution of Fe(NO_3)_2 and HNO_3 is allowed to stand in air.

The chemical equation follows:

3Fe(NO_3)_2+4HNO_3\rightarrow 3Fe(NO_3)_3+NO+H_2O

By Stoichiometry of the reaction:

3 moles of iron(II) nitrate reacts with 4 moles of nitric acid to produce 3 moles of iron(III) nitrate, 1 mole of nitric oxide and 1 mole of water.

  • <u>For f:</u> FeCO_3 is added to a solution of HClO_4

The chemical equation follows:

FeCO_3+2HClO_4\rightarrow Fe(ClO_4)_2+CO_2+H_2O

By Stoichiometry of the reaction:

1 mole of iron(II) carbonate reacts with 2 moles of perchloric acid to produce 1 moles of iron(II) perchlorate, 1 mole of carbon dioxide and 1 mole of water.

  • <u>For g:</u> Fe is heated in air

The chemical equation follows:

2Fe+O_2\rightarrow 2FeO

By Stoichiometry of the reaction:

2 moles of iron reacts with 1 mole of oxygen gas to produce 2 moles of iron(II) oxide.

Hence, the chemical equations are given above.
