After the addition of the iron, the test tube now contains iron (II) sulfate solution and copper
particles. The iron has become part of a
A
compound with the sulfate, which must be separated through chemical methods
B
compound with the sulfate, which can be separated through physical methods
C.
mixture with the sulfate, which must be separated through chemical methods
D. mixture with the sulfate, which can be separated through physical methods

Answers

The iron has become part of a A. compound with the sulfate, which must be separated through chemical methods.

Iron (II) sulfate is also referred to as ferrous sulfate is a reducing agent. The hydrates form is used for the treatment of iron deficiency.

It should be noted that a chemical change is involved in the formation of iron (II) sulfate. It can't be separated by physical means and isn't reversible.

In this case, iron (II) sulfate will be separated by chemical methods.

Iron sulfate is a compound which can be separated through chemical methods.

Iron is present in a compound form with the sulfate, which must be separated through chemical methods because both iron and sulfate reacts with each other through making of chemical bonds with each other. Those elements that combine with each other chemically at a fix ratio can be separated from each other through chemical methods.

While on the other hand, in mixture substances combine with each other physically so they can be separated from each other through physical methods so we can conclude that iron sulfate is a compound which can be separated through chemical methods.

The chemical equation below shows the amount of the reactants used and the amount of only one of the products formed. How much water (H2O) should be formed in this chemical reaction? CH4 mass 4 + 2O2 mass 16 CO2 11 + 2h2O mass ?

Answers

Answer:

CH4 + 2O2 → CO2 + 2H2O

Explanation:

This is all i could come up with im sorry.

The amount of water formed in the given chemical reaction is 9 grams.

What is Stoichiometry?

Stoichiometry is the calculation for the determination of the relative amount of reactants and products in chemical reactions. Stoichiometry is based on the law of conservation of mass where the total mass of the reactants in reaction equals the total mass of the products.

If the quantity of one reactant is known and the quantity of the product can be determined empirically, then the quantity of the other reactants can be calculated.

Given chemical equation is:

CH₄  +   2O₂  [tex]\longrightarrow[/tex]   CO₂   +   2H₂O

16g        32g         44g           32g        (from their molecular masses)

The amount of methane, oxygen, and carbon dioxide is 4g, 16g, and 32 g respectively.

16g of methane react with oxygen = 32g

4g of  methane will react with oxygen = 8g

It means here methane is the limiting reagent as the given amount of oxygen is more than reacted one.  So CH₄ will decide the amount of water.

16g of methane produces water = 32g

Then 4g of methane will produce water = (32/16) × 4 = 9 g

Therefore, 9 grams of water should be formed in this reaction.

How many moles are there in a 122 gram sample of nickel (Ni)?
7.16 x 103 moles
6.22 mol
2.08 mol
0.481 mol

Answers

the molecular weight of nickel is 58.69 g/mol. thus in a 122 gram sample of nickel there are 122/58.69=2.08 moles of nickel.

The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.

Nickel:

The atomic number of nickel is 28.The symbol of nickel is Ni.Density of a nickel 8.908 g/cm3.It is a d block element.It belongs to group 10 and period 4.It is also called transition metal.It is a metal and is located between groups 2 and 3.

Mass of nickel given: 122 grams.

Atomic mass of nickel: 58.71 g mol

Number of moles = Mass / molar mass

                             = 122/ 58.71

                              = 2.078

                              = 2.08 moles.

The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.

Answers

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Answer:

While covalent bonding involves sharing electrons between two atoms, ionic bonding involves the complete transfer of electrons from one atom to another, creating positive and negative ions. These ions are then held together by the attraction between their opposite charges.

What are subatomic particles?

An electron is defined as a subatomic particle which is charged negatively either bound to an atom or not it means free. The nucleus of an atom is made up of electron, proton and neutron. The electron is a basic particle and electron is not made of anything.

The nature of electron is free it means they are present freely in nature and consist of an atom.The main function of electron is that they play the role of negatively- charged component of an atom.

The electrons are primary source of current conducting and electrons number as well as atomic number of an element is always same or equal. There is no size of electron but the mass of electron is 9×10^-31.

Therefore,The subatomic particles are found in the nucleus of an oxygen atom are  Protons and Neutrons. Thus, option H is correct.
