The limiting reactant is chlorine (Cl2).

Explanation:

Limiting reactant is the amount of product formed which gets limited by the reagent without continuing it.

2 Al + 3 Cl2 ==> 2 AlCl3 represents the balanced equation.

Number of moles Al present = 34 g Al x 1 mole Al / 26.98 g

= 1.260 g moles of Al

Number of moles Cl2 present = 39 g Cl2 x 1 mole Cl2 / 35.45 g

= 1.10 g moles of Cl2

Dividing each reactant by it's coefficient in the balanced equation obtains:

1.260 moles Al / 2 = 0.63 g moles of Al

1.11 moles Cl2 / 3 = 0.36 g moles of Cl2

The reactant which produces a lesser amount of product is called as limiting reactant.

Here the Limiting reactant is Cl2.

What is the formula of the hydride formed by germanium?

Nadusha1986 [10]

The atoms combine to form compounds to attain stability in nature. The combination of atoms takes place by sharing of electrons between the atoms or complete transfer of electrons from one atom to another. Generally, atoms combine to complete their octet, that is to possess eight electrons in their outer most shell (noble gas configurations) except hydrogen which can attain stability by two electrons in its outer most shell.

Since germanium has 4 electrons in its outer most shell so it needs 4 more electrons to complete its octet and attains the stability. Hydrogen has 1 electron in its outer most shell and it needs only 1 electron to attain stability so, each germanium will combine with 4 hydrogen atoms and thus forming $GeH_4$ molecule which is stable in nature.

Hence, $GeH_4$ is the formula of the hydride formed by germanium.

Sort the following elements in order from least reactive to most reactive.

SVEN [57.7K]

Sorting the chemical elements in order from least reactive to most reactive, we have:

1. Fluorine (F).

2. Arsenic (As).

3. Antimony (Sb).

4. Silicon (S).

Given the following chemical elements:

Antimony (Sb).

Silicon (S).

Fluorine (F).

Arsenic (As).

Reactivity can be defined as a chemical property which determines how readily a chemical element bonds with other chemical elements, in order to form a new chemical compound.

Generally, the ability of a chemical element to bond with other chemical elements is largely (highly) dependent on the number of valence electrons it has in the outermost shell of its atomic nucleus.

As a general rule, chemical elements that are having fewer number of valence electrons are the most reactive while those having higher valence electrons are least reactive.

Also, chemical reactivity decreases down a group on the periodic table.

Based on the periodic table, the valency for the given chemical elements are:

Antimony (Sb): 5 valence electrons.

Silicon (S): 4 valence electrons.

Fluorine (F): 7 valence electrons.

Arsenic (As): 5 valence electrons.

In conclusion, sorting the chemical elements in order from least reactive to most reactive, we have:

1. Fluorine (F).

2. Arsenic (As).

3. Antimony (Sb).

4. Silicon (S).
