Where are the protons and neutrons and electrons located in an atom?

Answers

Answer 1

Answer: The protons and neutrons are located in the nucleus of an atom, while the electrons are located in the orbital cloud.

Answer 2

Answer:

Final answer:

Protons and neutrons are found in the nucleus of an atom while electrons are found in orbitals surrounding the nucleus. The number of protons determines the type of element the atom is.

Explanation:

In an atom, protons and neutrons are located in the nucleus, which is the central part of the atom. The electrons on the other hand, are situated in the areas around the nucleus called electron shells or orbits. Protons carry a positive charge, neutrons are neutral, and electrons carry a negative charge. The number of protons in an atom is what determines the atomic number and thus, the type of element it is.

In a synthesis reaction you start with 1.7L of hydrogen, how many liters of water will be produced

Answers

Answer:

1.7L of water.

Explanation:

Given parameters:

Volume of hydrogen gas = 1.7L

Unknown:

Volume of water produced = ?

Solution:

A synthesis reaction is one in which two compounds or molecules combines together to give a product or products.

Synthesis of water from hydrogen gas is represented by the equation below:

2H₂ + O₂ → 2H₂O

We clearly see that;

2 mole of hydrogen gas gives 2 mole of water as the product;

From Gay-lussac's law of combining volume "when gases react, they do so in volumes which bear a simple ratio to one another and to the volume of the product if gaseous, temperature and pressure remaining constant".

2H₂ + O₂ → 2H₂O

2 volumes of hydrogen gas will produce 2 volumes of water

1.7L of hydrogen gas will also produce ; 1.7L of water.

Which equation shows conservation of atoms?A) H2 + O 2 --> H2O
B) H2 + O 2 --> 2H2O
C) 2H2 + O2 --> 2H2O
D) 2H2 + 2O2 --> 2H2O

Answers

Answer: The equation showing conservation of atoms is $2H_2+O_2\rightarrow H_2O$

Explanation:

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This also means that total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.

For the given chemical equations:

Option A:

The given chemical equation follows:

$H_2+O_2\rightarrow H_2O$

There are 2 hydrogen atoms and 2 oxygen atoms on the reactant side and 2 hydrogen and 1 oxygen atom on product side.

So, this equation does not show conservation of atoms.

Option B:

The given chemical equation follows:

$H_2+O_2\rightarrow 2H_2O$

There are 2 hydrogen atoms and 2 oxygen atoms on the reactant side and 4 hydrogen atoms and 2 oxygen atoms on product side.

So, this equation does not show conservation of atoms.

Option C:

The given chemical equation follows:

$2H_2+O_2\rightarrow H_2O$

There are 4 hydrogen atoms and 2 oxygen atoms on the reactant side and 4 hydrogen atoms and 2 oxygen atoms on product side.

So, this equation shows conservation of atoms.

Option D:

The given chemical equation follows:

$2H_2+2O_2\rightarrow 2H_2O$

There are 4 hydrogen atoms and 4 oxygen atoms on the reactant side and 4 hydrogen atoms and 2 oxygen atoms on product side.

So, this equation does not show conservation of atoms.

Hence, the equation showing conservation of atoms is $2H_2+O_2\rightarrow H_2O$
