Arturiano [62]3 years ago

the balanced equation for the reaction is

N₂ + 3H₂ --> 2NH₃

since number of moles of gas is directly proportional to volume of gas once all other parameters are kept constant

the volume ratio of reactant gases is equal to molar ratio

therefore volume ratio of H₂ to NH₃ is 3:2

so 3 L of H₂ reacts to produce 2 L of NH₃ assuming N₂ is in excess

when 3.6 L of H₂ reacts  - 2/3 x 3.6 L = 2.4 L of N₂ is formed

So 2.4 L of NH₃ is produced

Answer:

2.4 L is the correct answer

Explanation:

volume ratio= 2NH3/3H2

3.6*2/3=2.4 L

I this isn't clear enough the other person has a really good explanation.

2. Choose the atom from each of the following pairs with the greater ionization energy: a. Be and Ba b. Al and Ar c. Ca and Cl
beks73 [17]

Considering the definition of ionization energy, the highest ionization energy belongs to the element:

a. Be

b. Ar

c. Cl

Electrons are held in atoms by their attraction to the nucleus, which means that energy is needed to remove an electron from the atom.

You should keep in mind that the electrons of the last layer are always lost, because they are the weakest attracted to the nucleus.

Ionization energy, also called ionization potential, is the necessary energy that must be supplied to a neutral, gaseous, ground-state atom to remove an electron from an atom. When an electron is removed from a neutral atom, a cation with a charge equal to +1 is formed.

In a group, the ionization energy increases upwards because when passing from one element to the bottom, it contains one more layer of electrons. Therefore, the valence layer electrons, being further away from the nucleus, will be less attracted to it and it will cost less energy to pluck them.

In the same period, in general, it increases as you shift to the right. This is because the elements in this way have a tendency to gain electrons and therefore it will cost much more to tear them off than those on the left which, having few electrons in the last layer will cost them much less to lose them.

Considering all the above, from each of the pairs, the highest ionization energy belongs to the element:

a. Be

b. Ar

c. Cl

Elements that have the following qualities: Lustrous, Solid at Room Temperatures, They react and form Basic Compounds, Great con
Tatiana [17]

Answer:

They are classified as METALS.

Explanation:

Elements are simple substances that cannot be chemically broken down into smaller substances. Based on different characteristics, they are classified into 3 namely:

- metals

- non metals and

- metalloid( mainly act as semi- conductor).

METALS are the type of elements that loses electrons to form positive ion, that is, they are electropositive elements. They are distinguished by the following characteristics:

- LUSTROUS: they have the ability to reflect light from its surface.

- At room temperature: Metals are solid are room temperature with the exception of Mercury which is liquid at room temperature.

- They react and form Basic Compounds

- Great conductor: most metals are great conductors of heat and electricity because they possess free electrons.

- Melting Point: they have high melting points.
