If you have 98 grams of sodium chloride, 47 grams of silver nitrate, and 59 grams of silver
chloride, then how many grams of sodium nitrate will you have?

145 grams
86 grams
18 grams
101 grams

Answers

Based on the mass ratio of reactants, 23.5 g of sodium nitrate is produced from the reactants.

What is mass ratio of a chemical reaction?

The mass ratio of a reaction is the ratio of the masses of reactants wilhich combine to form products.

The mass of sodium nitrate is determined from the mass ratio.

The equation of the reaction gives the mass ratio as follows:

NaCl + AgNO3 ----> AgCl + NaNO3

Molar mass of NaCl = 58.5 g

Molar mass of AgNO3 = 170 g

Molar mass of AgCl = 143.5

Molar mass of NaNO3 = 85 g

There are 98 grams of sodium chloride, 47 grams of silver nitrate, therefore silver nitrate is the limiting reactant.

47 grams of silver nitrate will produce 85/170 × 47 = 23.5 g of sodium nitrate.

Therefore, 23.5 g of sodium nitrate is produced from the reactants.

The difference between the amount of heat actually released upon the hydrogenation of benzene and that calculated for the hydrogenation of an imaginary cyclohexatriene is called the _________ of benzene.

Answers

From what we know, we can confirm that the difference measured by the experiment in the heat released when compared to the hydrogenation of an imaginary cyclohexatriene is called the stabilization energy of benzene.

What is stabilization energy?

This is a term used to describe the difference in measured energy of a chemical structure compared to the theoretical energy amounts expected to be measured. In this experiment, the heat that was released did not match the calculated energy expected, which is a prime example of stabilization energy at work.

Therefore, we can confirm that the difference measured by the experiment is called the stabilization energy of benzene.

It should be noted that to calculate Kf for t butyl alcohol, we need to calculate molality.

How to calculate Kf

Your information is incomplete as the figures are not given. Therefore, an overview will be given. To calculate Kf for t butyl alcohol, we need to calculate molality.

Molality will be calculated as:

= mass of solute / (molar mass of solute × mass of solvent)

For example, if the solution has a molality of 0.455 that freezes at 3.17 degrees Celsius, then Kf would be equal to 3.17 divided by 0.455 which is 6.96 degrees Celsius.

There are 31.1 grams (g) in 1 troy ounce (ozt). How many ozt of gold are extracted from 1 short ton of average Nevada ore

Answers

This problem is providing us with the mass equivalent to one troy ounce. Thus, the troy ounces of gold in one short ton of average Nevada ore is required and found to be the 0.103 otz according to the following dimensional analysis.

Dimensional analysis

In chemistry, a raft of problems do not always provide an equation in order to be solved yet dimensional analysis can be applied, so as to obtain the desired amount in the required units.

Thus, since this problem asks for try ounces in an average Nevada ore,  which has 3.2 grams of gold per short ton of ore, one can solve the following setup in order to obtain the required answer in otz:

[tex]\frac{3.2gAu}{1short-ton}*1short-ton*\frac{1otz}{31.1g} \\[/tex]

Lead is a toxic metal that affects the central nervous system. A Pb-contaminated water sample contains 0.0011 %Pb by mass. How much of the water (in mL) contains 160 mg of Pb? (Assume a density of 1.0 g/mL.)

Answers

In 145.45 grams of water there are 160mg of 0.0011% Pb.

Solution concentration

To resolve this issue, it is necessary to use the concentration of solutions, which indicates the percentage amount of one solvent or solute in relation to the other.

In the case of the question, we have that Pb is at a concentration of 0.0011%, that is, for every 100 grams of water we have 0.0011 grams of Pb.

So, to calculate the amount of water that we have 160mg of Pb, we will make the following expression:

                                           Pb           H2O

                                            [tex]\frac{0.0011g}{160\times 10^ {-3}g} =\frac{1g}{x}[/tex]

                                            [tex]x = 145.45g[/tex]

So, in 145.45 grams of water there are 160mg of 0.0011% Pb.

Balance the following equation and express the rate in terms of the change in concentration with time for each substance: NO(g) O2(g) LaTeX: \longrightarrow N2O3 (g) When N2O3 is forming at 0.221 M/s, at what rate is NO decreasing

Answers

The balanced equation is:

4 NO(g) + O₂(g) ⇒ 2 N₂O₃(g)

The expression of the rate in terms of change in concentrations are:

[tex]v = \frac{-\Delta [NO]}{4\Delta t } = \frac{-\Delta [O_2]}{1\Delta t } = \frac{\Delta [N_2O_3]}{2\Delta t }[/tex]

When N₂O₃ is forming at 0.221 M/s, NO is disappearing at 0.442 M/s.

What is the reaction rate?

The reaction rate is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.

Step 1: Write the balanced equation.

4 NO(g) + O₂(g) ⇒ 2 N₂O₃(g)

Step 2: Express the rate in terms of the change in concentration with time for each substance.

We will need to consider the stoichiometric coefficient of each species.

[tex]v = \frac{-\Delta [NO]}{4\Delta t } = \frac{-\Delta [O_2]}{1\Delta t } = \frac{\Delta [N_2O_3]}{2\Delta t }[/tex]

Step 3: Given the rate of formation of N₂O₃ is 0.221 M/s, calculate the rate of disappearance of NO.

The molar ratio of NO to N₂O₃ is 4:2.

[tex]\frac{0.221molN_2O3}{L.s} \times \frac{4molNO}{2molN_2O_3} = \frac{0.442 molNO}{L.s}[/tex]

The balanced equation is:

4 NO(g) + O₂(g) ⇒ 2 N₂O₃(g)

The expression of the rate in terms of change in concentrations are:

[tex]v = \frac{-\Delta [NO]}{4\Delta t } = \frac{-\Delta [O_2]}{1\Delta t } = \frac{\Delta [N_2O_3]}{2\Delta t }[/tex]

When N₂O₃ is forming at 0.221 M/s, NO is disappearing at 0.442 M/s.

What is the amount in grams of EDTA needed to make 315.1 mL of a 0.05 M EDTA solution. The molar mass of EDTA is 374 g/mol

Answers

Answer:

58.92 g EDTA

Explanation:

315.1 mL = .3151 L    

M = Moles / Liter

.3151 L  x 0.5 mol EDTA  x  374 g EDTA  =  58.92 g EDTA

                1 L EDTA             1 mol EDTA

The amount in grams of EDTA needed to make 315.1 mL of a 0.05 M is equal to 5.89 g.

Molar concentration

In a 0.05M solution, there are 0.05 moles of the substance per 1 liter, that is, in 315.1 ml we have:

                                        [tex]\frac{0.05 mol}{xmol}= \frac{1000ml}{315.1ml}[/tex]

                                           [tex]x = 0.016 mol[/tex]

Thus, 0.016 mol EDTA of  is needed to prepare the solution.

Mass calculation

To calculate the mass in an amount of moles, we use the molar mass, so that:

                                          [tex]m = MM \times mol[/tex]

                                         [tex]m = 374 \times 0.016[/tex]

                                             [tex]m = 5.89 g[/tex]

So, the amount in grams of EDTA needed to make 315.1 mL of a 0.05 M is equal to 5.89 g.
