The balanced chemical equation for this chemical reaction between solid sulfur and oxygen gas is: $2S_{(s)} + 3O_2_{(g)}$ $--- 2SO_3_{(g)}$

A balanced chemical equation can be defined as a chemical equation wherein the number of atoms on the reactant (left) side is equal to the number of atoms on the product (right) side.

Hence, both the charge on each atom and sum of the masses of the chemical compounds or elements in a chemical equation are properly balanced.

In order to use a chemical equation to conduct stoichiometric analysis, the chemical equation must be properly balanced.

Note: The chemical element sulfur (S) in its solid state reacts with oxygen gas ( O_2 ) to form SO_3 gas.

Therefore, balanced chemical equation for this chemical reaction between solid sulfur and oxygen gas is:

$2S_{(s)} + 3O_2_{(g)}$ $--- 2SO_3_{(g)}$

The given question is incomplete. The complete question is:

Elemental S reacts with O_2 gas to form SO_3 gas according to the reaction depicted here.

Before a chemical equation can be used to conduct stoichiometric analysis, it must balanced. Type the balanced chemical equation for this reaction between solid sulfur and oxygen gas.

Express your answer as a chemical equation including phases.

$2S(s)+3O_2(g)\rightarrow 2SO_3(g)$

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas. Liquids are represented by (l) and gases are represented by (g).

The balanced chemical reaction will be:

$2S(s)+3O_2(g)\rightarrow 2SO_3(g)$

Answer from: Quest

assuming that your periodic table has eighteen columns, you should highlight the four elements in the third column from the left of the table.

explanation

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the $3d$ have energy higher than those in the $4 s$ orbital while lower than those of the $4 p$ orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the $4s$ orbital is therefore filled right after $3p$ orbitals and before $3 d$ orbitals.

potassium has electron configuration $[\text{ar}] 4 s^{1}$ and calcium $[\text{ar}] 4 s^{2}$ . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration $[\text{ar}] 4 s^{2} \; 3d^{1}$ and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the $ns^{2} \; (n-1) p^{1}$ and should be highlighted as well.
