Trinitrotoluene (TNT), C7H5N3O6, combines explosively with oxygen to produce CO2, water, and N2. Write a balanced chemical equat
Norma-Jean [14]

Answer:

2 C₇H₅N₃O₆ + 10.5 O₂ → 14 CO₂ + 5 H₂O + 3 N₂

73.96 g

Explanation:

Trinitrotoluene (TNT), C₇H₅N₃O₆, combines explosively with O₂ to produce CO₂, H₂O, and N₂. The balanced equation is:

2 C₇H₅N₃O₆ + 10.5 O₂ → 14 CO₂ + 5 H₂O + 3 N₂

The molar mass of C₇H₅N₃O₆ is 227.13 g/mol and there are 2 moles in the balanced equation. Then, 2 × 227.13 g = 454.26 g participate in the reaction.

The molar mass of O₂ is 31.998 g/mol and there are 10.5 moles in the balanced equation. Then, 10.5 × 31.998 g = 335.98 g participate in the reaction.

The mass ratio of C₇H₅N₃O₆ to O₂ is 454.26 g:335.98 g. The mass of O₂ that reacts with 100.0 g of TNT is:

100.0 g C₇H₅N₃O₆ × (335.98 g O₂/454.26 g C₇H₅N₃O₆) = 73.96 g O₂

Which of the following statements is NOT true?
maria [59]

Answer : The incorrect statements are:

(A) When two nonmetals react, the compound formed is ionic.

(B) Two nonmetals can undergo an oxidation-reduction reaction.

Explanation :

Covalent compound : It is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound.

The covalent compound are usually formed when two non-metals react.

The two nonmetals can not undergo an oxidation-reduction reaction.

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

Ionic compound are usually formed when a metal reacts with a non-metal.

The metal-nonmetal reaction can always be assumed to be an oxidation-reduction reaction.

For example : 2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)

In this reaction, sodium shows oxidation because the oxidation state changes from (0) to (+1) and and chlorine shows reduction because the oxidation state changes from (0) to (-1).

Hence, the incorrect statements are, (A) and (B)

Do electrons spin in the same direction within an orbital?​
tester [92]

Answer:

in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
