Answer:

Lets Write Down the Given Initial Conditions.

P_1 = 751mmHg           P_2 = --

V_1 = 63.2ml                V_2 = 47.6ml

T_1 = 42C                     T_2 = 77

In Order to Solve for the Unknown: P_2

we must use the Ideal Gas Law to Solve for the Second Unknown pressure:

\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}

Then Rearrange this equation in a form where P2 can be solved from:

P_2 = \frac{P_1V_1T_2}{T_1V_2}

Then Insert the Values from above to solve:

P_2 = \frac{(751 mmHg)(63.2ml)(77C)}{(47.6ml)(42C)}

The Answer is : 1830 mmHg considering sig figs

Understanding how much of a product is produced in a reaction is referred to as ________ understanding the reaction?
777dan777 [17]
Hello!

Understanding how much of a product is produced in a reaction is referred to as Stoichiometrically understanding the reaction.

Stoichiometry is the calculation of the quantitative relationships between reactants and products in a chemical reaction. The first to talk about stoichiometry was Jeremias Benjamin Ritcher, who said that "Stoichiometry is the science that measures the quantitative proportions or mass ratios of chemical elements that are involved in a chemical reaction".

To calculate how much of a product is produced in a reaction, Stoichiometry is used, applying the law of conservation of mass. That means that the amount of product can be calculated from the amounts of reactants if they are known.

For the chemical reaction , I identify the reactant and the products .
svetlana [45]

The reactant is Mercury (II) Oxide while the products are Mercury and Oxygen separately.

This is because the reactants are typically always on the left side of the yields symbol. In this decomposition reaction, it would still be the same as at the end of the reaction, there were to products produced: Mercury and Oxygen.

Products tend to always be on the right side of the yields symbol, they're what comes out of a reaction no matter what type.

Hope this helps!

A 0.24g sample of compound of oxygen and boron was found by analysis to contain 0.144g of Oxygen.calculate the percentage compos
oksano4ka [1.4K]

Answer:

Mass of compound = 0.24 g and, mass of boron = 0.096 g percentage of boron in the compound = mass of boron / mass of compound * 100 = 0.096/0.24 * 100 = 40% mass of oxygen = 0.144 g again, mass of compound = 0.24 g percentage of oxygen in compound = mass of oxygen/mass of of compound * 100 = 0.144/0.24 * 100 = 60%

The mass defect for the formation of lithium-6 is 0.0343 g/mol. The binding energy for lithium-6 nuclei is ________ kJ/mol. Ente
Sholpan [36]

<u>Answer:</u> The binding energy for lithium-6 nuclei is 3.09 E+11

<u>Explanation:</u>

Binding energy is defined as the energy which holds the nucleus together. It is basically the product of mass defect and the square of the speed of light.

This energy is calculated by using Einstein's equation, which is:

E=\Delta mc^2

where,

E = Binding energy of the atom

Delta m = Mass defect = 0.0343g/mol = 0.0343\times 10^{-3}kg/mol     (Conversion factor: 1kg=10^3g )

c = speed of light = 3\times 10^8m/s

Putting values in above equation, we get:

E=0.0343\times 10^{-3}kg/mol\times (3\times 10^8m/s)^2

E=3.09\times 10^{14}J/mol=3.09\times 10^{11}kJ/mol     (Conversion factor: 1kJ=10^3J )

Hence, the binding energy for lithium-6 nuclei is 3.09 E+11
