The correct option is A.

The percentage error in the measurement of the density is about 12%.

The error in any measurement is the difference between the actual measurement of the substance and the estimated measurement of the substance.

The percentage error is obtained by dividing the error in the measurement by actual measurement and multiply the result by 100%.

The average density measurement = 6.5 g/mL

error = actual measurement - estimated measurement

error = 7.4 g/mL - 6.5 g/mL

error = 0.9 g/mL

percentage error = (0.9 / 7.4) x 100%

percentage error = 12.16 %

The theoretical yield of C that is obtained is 13.26 g.

We know that the theoretical yield has to do with the amount of the substance that is obtained as we can get it from the stoichiometry of the balanced reaction equation. Hence the first step that we have to carry out is to try to obtain the balanced reaction equation that can be used to describe the reaction as it has been shown.

The balanced reaction equation is;

6 A(aq) + 7 B(aq) → 7 C(s) + 6 D(g)

Number of moles of A = 4.0 L * 0.20 M = 0.8 moles

Number of  moles of B =  3.0 L * 0.20 M = 0.6 moles

Now;

6 moles of A reacts with 7 moles of B

0.8 moles of A reacts with 0.8 moles * 7 moles/6 moles

= 0.93 moles

Thus B is the limiting reactant.

If  7 moles of B yleds 7 moles of C

Amount of C obtained = 0.6 moles

Mixing an acid and a base does not necessarily neutralize them. Neutralization refers to the situation where equal parts of acid and base are mixed.

If equal parts of a strong acid and a strong base are mixed, the pH of the resulting solution will be very close to 7 depending on factors such as temperature. However, if a strong base is used to neutralize a weak acid the resulting solution will have a pH greater than 7 basic and if a weak base is used to neutralize a strong acid, the resulting pH will be less than 7.

It is therefore not entirely correct to say that all acid-base reactions are examples of neutralization only those where acids and bases are mixed in stoichiometrically equal amounts. Hazardous material spills must be absorbed, neutralized, or controlled in the event of an accident to ensure workplace safety.

The temperature reading on Fahrenheit scale is related to the The temperature reading on Celsius scale by a linear equation F = 9/5 C + 32

Data for Fahrenheit temperature scale:

Water freezing point = 32⁰

Water boiling point = 212⁰

Therefore, the scale is divided into 212 - 32 = 180 scales.

Data for Celsius temperature scale:

Water freezing point = 0⁰

Water boiling point = 100⁰

Therefore, the scale is divided into 100 - 0 = 100 scales.

Scale ratio:

C : F = 100 : 180 = 5 : 9

It means each increment of 1⁰ on Celsius scale is equal to an increment of 9/5 degree on Fahrenheit scale. However, we need to add an offset 32⁰ on Fahrenheit scale.

Hence,  the reading C⁰ on Celsius scale is equivalent to:

Answer:

gram (g), kilogram (kg) and tonne (t).

Explanation:

Answer: 26g

Explanation:

First, write the correctly balanced equation for the reaction taking place:

HBr(aq) + NaOH(s) ==> NaBr(aq) + H2O(l) ...  balanced equation

Next, find out which reactant is limiting. An easy way is to just divide the moles of each reactant by the corresponding coefficient in the balanced equation (1 for both in this case):

HBr:  46.1 g HBr x 1 mol HBr / 80.9 g = 0.570 moles

NaOH:  10. g NaOH x 1 mol NaOH / 40. g = 0.25 mols NaOH

NaOH is limiting and will determine the maximum amount of product that can form.

Maximum amount of NaBr that can form:

0.25 mols NaOH x 1 mol NaBr / 1 mol NaOH x 103 g NaBr / mol = 25.75 g NaBr = 26 g NaBr (2 s.f.)

The mass of water produced is 35.27g in the given chemical reaction.

A chemical reaction is the chemical change of one set of chemical components into another. A chemical reaction is the process through which two or more molecules combine to create a new product(s). Compounds that combine to make new compounds are referred to as reactants, while the newly produced compounds are referred to as products. When chemical bonds between atoms are established or destroyed, chemical reactions occur. Breaking chemical bonds between reactant molecules and establishing new bonds between atoms in product particles are examples of chemical reactions. The number of atoms is the same before and after the chemical transition, but the number of molecules changes.

Given:

Mass of hexane = 43g

Mass of oxygen = 85.1g

To find:

Mass of water formed = ?

Calculations:

According to the balanced equation, 2 moles of hexane react with 19 moles of oxygen to form 12 moles of carbon dioxide and 14 moles of water.

Molar mass of hexane = 86.118g/mol

Molar mass of oxygen = 32g/mol

(2 x 86.118)g of hexane required = (19 x 32)g of oxygen

43g of hexane required = (19 x 32) / (2 x 86.118) x 43

= 151.79g of oxygen

But we have only 85.1g of oxygen, thus it is a limiting reagent

Now,

(19 x 32)g of oxygen reacts to produce = (14 x 18)g of water

85.1g of oxygen reacts to produce = (14 x 18) / (19 x 32) x 85.1

= 35.271g of water

Result:

35.27g of water is produced.

Based on the balanced reaction equation, 9 moles of carbon dioxide are formed when 3 moles of propane are combusted.

From the balanced reaction equation we can see that 3 moles of carbon dioxide are formed upon the combustion of a single mol of propane:

C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O

These molar ratios are constant and enable us to set up a simple proportion:

1 mol of propane : 3 mol of carbon dioxide = 3 mol of propane : X

X = 3 mol of carbon dioxide * 3 mol of propane / 1 mol of propane

X = 9 mol of carbon dioxide

Because red and its complementary hue, green, are communicated, we see CoCl2 as a red color. Green, however, is its complementary color and is what is absorbed. The only color that can be seen is the color that is communicated. Red is what we can see, not green.

The logarithm of the ratio of incident to transmitted radiant power through a sample is known as absorbance. As an alternative, absorbance can be defined as "the negative logarithm of one minus absorptance, as measured on a homogeneous sample," for samples that scatter light.

As opposed to absorption, which occurs when electrons move up to a higher energy state from a lower energy state, emission occurs when electrons move down to a lower energy state, giving rise to a negative energy. When electrons undergo an energy change that is positive and migrate from one state of lower energy to another, this is called absorption.

Based on Beer's law and the data provided (molar absorptivity, number of moles, volume of the solution, cell dimension) we can calculate that the absorbance of the sample will be 0.42336.

According to Beer's law, the measured absorbance is proportional to the molar absorptivity of the substance, its molarity in the sample, and the pathlength of the cell:

A = ε * c * l

ε - molar absorptivity (252 M⁻¹cm⁻¹)

c - molarity of the sample

l - pathlength (6.00 mm = 0.6 cm)

To calculate the absorptivity we need to calculate the molarity of the sample:

c = n/V = 0.00140 mol / 0.5000 L = 0.00280 M

A = 252 M⁻¹cm⁻¹ * 0.00280 M * 0.6 cm = 0.42336
