Nitroglycerin is a dangerous powerful explosive that violently decomposes when it is shaken or dropped. The Swedish chemist Alfr
marshall27 [118]

<u>Answer:</u> The balanced chemical equation for the decomposition of nitroglycerin is written below.

<u>Explanation:</u>

Decomposition reaction is defined as the reaction in which a single large substance breaks down into two or more smaller substances.

Every balanced chemical equation follows law of conservation of mass.

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

The balanced chemical equation for the decomposition of nitroglycerin follows:

4C_3H_5N_3O_9(l)\rightarrow 12CO_2(g)+10H_2O(g)+6N_2(g)+O_2(g)

By Stoichiometry of the reaction:

1 mole of liquid nitroglycerin decomposes into 12 moles of carbon dioxide gas, 10 moles of gaseous water, 6 moles of dinitrogen gas and 1 mole of dioxygen gas.

Hence, the balanced chemical equation for the decomposition of nitroglycerin is written above.

The number of neutrons in an atom affects the atomic what of the atom?
Zigmanuir [339]
The number of neutrons in a nucleus affects the mass of the atom but not its chemical properties. Thus, a nucleus with six protons and six neutrons will have the same chemical properties as a nucleus with six protons and eight neutrons, although the two masses will be different.

What does h20 mean on the periodic elements chart
Paladinen [302]

Answer:

The compound, H₂O, will not be found on the periodic table. This is because the periodic table only consists of individual elements. That being said, the elements found within H₂O are located on the periodic table. H₂O consists of hydrogen, denoted by the symbol "H", and oxygen, denoted by the symbol "O". The subscript (the 2) tells us that there are 2 hydrogen atoms located in the H₂O molecule.

Hydrogen is the first element listed on the periodic table and can be found in the top leftmost position. Oxygen is the eighth element on the periodic able and is located in the second row at the top right.

A 20.00 mL Ba(OH)_2 solution of unknown concentration was neutralized by the addition of 47.67 mL of a 0.1236 M HCl solution. Wr
dalvyx [7]

Answer:

- Balanced chemical reaction:

2HCl(aq) + Ba(OH)_2(aq) \rightarrow BaCl_2(aq) + 2H_2O(l)

- Concentration of the initial barium hydroxide solution:

M_{Ba(OH)_2}=0.1473M

- Concentrations of barium and chloride ions:

M_{Ba^{2+}}=0.04353M\\M_{Cl^-}=0.08707M

Explanation:

Hello,

In this case, the balanced chemical reaction with the proper physical states is:

2HCl(aq) + Ba(OH)_2(aq) \rightarrow BaCl_2(aq) + 2H_2O(l)

Moreover, it is convenient to perform the titration analysis in terms of normalities, therefore, HCl's normality becomes equal to its molarity as it is monoprotic (only one hydrogen in its formula), thus, we find barium hydroxide's normality:

N_{Ba(OH)_2}=\frac{N_{HCl}V_{HCl}}{V_{Ba(OH)_2}}=\frac{0.1236N*47.67mL}{20.00mL}=0.2946N

Hence, for the molarity, since two hydroxiles are in the barium hydroxide, 2 grams-equivalents are 1 mole, thus, its molarity is:

M_{Ba(OH)_2}=0.2946\frac{eq-g}{L}*\frac{1mol}{2eq-g}=0.1473\frac{mol}{L}=0.1473M

Then, after mixing and carry out the neutralization reaction the resulting volume is:

V_{final}=20.00mL+47.67mL=67.67mL=0.067L

In addition, the moles of both barium and chloride ions are:

n_{Ba^{2+}}=0.02L*0.1473\frac{molBa(OH)_2}{L} *\frac{1molBa^{2+}}{1molBa(OH)_2} \\n_{Ba^{2+}}=2.946x10^{-3}mol Ba^{2+}\\\\n_{Cl^-}=0.04767L*0.1236\frac{molHCl}{L} *\frac{1molCl^-}{1molHCl} \\n_{Cl^-}=5.892x10^{-3}mol Cl^-

Finally, the concentrations of such ions are:

M_{Ba^{2+}}=\frac{2.946x10^{-3}molBa^{2+}}{0.06767L}= 0.04353M\\M_{Cl^-}=\frac{5.892x10^{-3}molCl^-}{0.06767L}= 0.08707M

Best regards.
