Answer:

13.672

Explanation:

2 moles of OH in Ba(OH)₂

0.235 M × 2 mol OH = 0.47 M OH

pOH = -log[OH-] ; pOH = -log[0.47 M OH] ; 0.328 = pOH (consider significant figures)

14 - pOH = pH because pH + pOH = 14

14 - 0.328 = 13.672 [there are three decimal places after the OH concentration, so there should be in the answer as well - 13.672]

We have 1.77 moles of sulfur in 56.8 g of sulfur.  It is a fundamental unit of measurement in the International System of Units (SI) and is defined as the amount of substance that contains the same number of entities as there are in 12 grams of carbon-12.

First, we need to use the formula:
Number of moles = Mass / Molar mass
In this case, the mass of sulfur is 56.8 g, and the molar mass of sulfur is 32.06 g/mol. Substituting these values into the formula, we get:
Number of moles = 56.8 g / 32.06 g/mol
Number of moles = 1.77 mol (rounded to two decimal places)

Therefore, we have 1.77 moles of sulfur in 56.8 g of sulfur. It is important to note that the number of moles is a measure of the amount of substance and is used extensively in chemistry calculations.The entities can be atoms, molecules, or ions, depending on the substance being measured.

Precision relates to the consistency and reproducibility of measurements, while accuracy reflects how close measurements are to the true value.

Precision and accuracy are two important concepts in the context of errors in measurements. While they both pertain to the quality of data, they refer to different aspects.

Precision refers to the degree of consistency or reproducibility in a series of measurements. It reflects the scatter or spread of data points around the average value. If the measurements have low scatter and are tightly clustered, they are considered precise. On the other hand, if the measurements have a high scatter and are widely dispersed, they are considered imprecise.

Accuracy, on the other hand, refers to the closeness of measurements to the true or target value. It represents how well the measured values align with the actual value. Accuracy is achieved when measurements have a small systematic or constant error, which is the difference between the average measured value and the true value.

Errors in measurements can be classified into two types: random errors and systematic errors.

Random errors are associated with the inherent limitations of measurement instruments or fluctuations in the measurement process. They lead to imprecise data and affect the precision of measurements. Random errors can be reduced by repeating measurements and calculating the average to minimize the effect of individual errors.

Systematic errors, on the other hand, are caused by consistent biases or inaccuracies in the measurement process. They affect the accuracy of measurements and lead to a deviation from the true value. Systematic errors can arise from factors such as instrumental calibration issues, environmental conditions, or experimental techniques. These errors need to be identified and minimized to improve the accuracy of measurements.

In summary, precision refers to the degree of consistency or reproducibility of measurements, while accuracy refers to the closeness of measurements to the true value. Random errors affect precision, while systematic errors affect accuracy. To ensure high-quality measurements, both precision and accuracy need to be considered and appropriate techniques should be employed to minimize errors.

Explanation:

Based on the heat of reaction, if 123 kJ of heat is evolved when the reaction described below is carried out, the mass of HCl gas (36.46 g/mol) produced is 23.6 g.

The heat of a reaction is the amount of heat energy given off or absorbed in the reaction.

During a reaction, energy changes occur as a result of the breaking of bonds in the reactants as well as the formation of bonds in the products.

The sum of the overall energy change that accompanies the formation of products from the reactants gives the heat change of a reaction.

Considering the heat change of the given reaction below:

3 Cl₂ (g) + PH₃ (g) → PCl₃ (g) + 3 HCl (g)     ∆H = - 570.4 kJ

The formation of 3 moles of HCl results in the evolution of 570.4 kJ of heat.

If 123 kJ of heat are evolved, then the moles of HCl produced will be:

Moles of HCl produced = 123 kJ * 3 moles / 570.4 kJ

Moles of HCl produced =  0.647 moles

Mass of HCl produced = 0.647 * 36.46

Mass of HCl produced = 23.6 g

Explanation:

The options which are not true of standard cell potentials are the anode are option B, C, and D.

The standard cell potential refers to the potential difference between the cathode and anode and measures the potential of equilibrium. The standard potentials are all measured at 298 K, 1 atm, and with 1 M solutions. In a galvanic cell, current is generated when electrons flow externally through the circuit from the anode to the cathode due to a difference in potential energy between the two electrodes in the electrochemical cell. A galvanic cell generates electric current spontaneously if its cell potential is positive. Standard cell potential is determined calculated as the standard reduction potential of the cathode minus the standard reduction potential of the anode. The cathode is always the species with the greater standard reduction potential, while the anode is the species with the lower standard reduction potential. The reduction potentials are not scaled by the stoichiometric coefficients when calculating the standard cell potential.
