Answer:

Jenna should: Verify the data by running the experiment several more times

Explanation:

Verifying your data can be done by running multiple trials to ensure that the results that come out was not due to other errors such as calculation mistakes, procedural errors, and the like. This will rule out other extraneous factors that could have unintentionally influenced the outcome of the experiment.

Answer:

Verify the data by running the experiment several more times is the correct answer.

Explanation:

If Jenna wants to support her current theory, it is necessary that she checks every step of the procedure at least one more time. To make sure that she doesn't miss anything, it is necessary that she repeats the experiment one or several times in order to verify that she is following the procedure as she should.

What is an extensive property that can be calculated?

padilas [110]

Answer: The property which depends on the quantity of the substance is called an extensive property. The free energy change for a reaction (Δ G) depends on the quantity of the substance and is therefore an extensive property. It shows the additive nature. The extensive property Δ G is easily calculated from the formula, ΔG = -nFE cell.

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

<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.
