The percentage yield of the new production technique is 82.8%
What is the percentage yield?Production is the procedure by which finished products are obtained form the raw materials. The production process involves the passing of raw materials through a certain procedure that involves the use of certain machines and equipment to give us the required products.
We are told in the question that there are three shifts;
Shift 1 produces 4562 grams
Shift 2 produces 5783 grams
Shift 3 produces 5247 grams
Average production from the three shifts = 4562 grams + 5783 grams + 5247 grams/3 = 5197 grams
The theoretical average yield is = 7000 grams + 7000 grams + 7000 grams/3 = 7000 grams
Now the percentage yield = actual yield/ theoretical yield * 100/1
percentage yield = 5197 grams/7000 grams * 100/1

The reaction between an alcohol and an anomeric carbon of a carbohydrate forms a _____ bond.
What is the pressure in atm exerted by 1.8 g of H_{2} gas exert in a 4.3 L balloon at 27°C? R =; 0.821(L^ * atm)/(mol^ * K)
Answer:
5.12 atm
Explanation:
Before you can use the Ideal Gas Law to find the pressure, you need to convert grams to moles (via molar mass).
Molar Mass (H₂): 2(1.008 g/mol)
Molar Mass (H₂): 2.016 g/mol
1.8 grams H₂ 1 mole
---------------------- x ---------------------- = 0.893 moles H₂
2.016 grams
The Ideal Gas Law equation looks like this:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = moles
-----> R = Ideal Gas Constant (0.0821 L*atm/mol*K)
-----> T = temperature (K)
After converting Celsius to Kelvin, you can plug the given values into the equation and simplify to find the pressure.
P = ? atm R = 0.0821 L*atm/mol*K
V = 4.3 L T = 27 °C + 273.15 = 300.15 K
n = 0.893 moles
PV = nRT
P(4.3 L) = (0.893 moles)(0.0821 L*atm/mol*K)(300.15 K)
P(4.3 L) = 22.0021
P = 5.12 atm
**Based on my past experiences, I believe the constant (R) you provided may have been mistyped. Instead of 0.821, I used 0.0821.**
Draw the major product formed in the reaction involving an acid anhydride dissolved in alcohol.
Ester is the major product formed in the reaction involving an acid anhydride dissolved in alcohol.
What is the chemistry of acid anhydrides?Acid chlorides and anhydrides both go through a number of similar reactions when subjected to nucleophilic action. Anhydrides react with water to generate carboxylic acids, with alcohols to form esters, and with amines to form amides, though they do so more slowly than acid chlorides. By using hydride reduction, anhydrides can also be converted to primary alcohols. As many anhydrides are created by coupling two carboxylic acids, one equivalent of the carboxylic acid is lost in anyhydride reactions as a leaving group. As a result, reactions are often only carried out using affordable, widely accessible anhydrides, such as acetic or benzoic. The advantage of anydrides over acid chlorides is that they are simpler to work with.Learn more about acid anhydride here:

The penny coin was removed from circulation in Canada
In February of 2014. The United States may soon do the
same. The major reason for this move was the rising value
of copper metal. When copper’s value increased, pennies
were produced as a zinc slug with a thin layer of copper
plated over top. Zinc reacts readily with hydrochloric acid,
while copper does not. A triangular file is used to nick the
edge of a penny to expose the zinc slug below the layer
of copper. The zinc reacts with the acid releasing bubbles
from the nicked area until nothing remains but a thin shell
of copper. If 0.948 L of hydrogen gas is collected over water
at 20.0°C and a total pressure of 752 mm Hg, determine the
percentage by mass of the copper in the 2.586 g penny.
As a result, the dry gas volume at STP is 45.58 cm 3.
Water vapor is present in the gas. Since H2 is created during the reaction and water vapor is irrelevant when determining the equivalent weight, we only need the dry gas. As a result, the volume of H2 gas can be calculated using the ideal gas law.
P 1 = 750 mm Hg, 14 mm Hg, 736 mm Hg V = 50 cm 3 T = 17 0 C = 290 K
P = 760mmHg, V =?cm3, T = 0 0 and C = 273K.
The Gas equation follows.
P 1V 1/ T1 = P 2V 2/ T2
290/73650 = 273/760V 2
= 290760V 2

The buffer capacity can be defined as the amount of strong base needed to change the pH of 1 liter of solution by 1 pH unit.
To increase buffer capacity to modify buffer solution-
The buffer capacity of a buffer, consisting of a weak acid and its conjugated base is given by the following equation:
π=㏑ 10 [{H⁺} + K ÷ H⁺ + CKα [H⁺] ÷ [H⁺] + Kα]
With [H^+] the concentration of the H^+ ion ; C the total buffer concentration (i.e. acid + conjugated base) and Kα the acidity constant.
It is clear from this equation that the buffer capacity is directly proportional to the concentration.
So the only way increase the buffer capacity is to increase the total concentration of the system (conjugated acid + base).

Explanation:
The condition of acidosis can cause ____________ because the higher h concentration diffuses to the icf, pushing k towards the ecf
Acidosis is a disorder in which there is excess acid in the body. This condition can lead to hyperkalemia due to the diffusion of hydrogen ions in the intracellular fluid.
What is hyperkalemia?Hyperkalemia is an increased concentration of the fluid potassium level than normal. Though potassium (K) is needed by the body for various functions of the nervous system and muscles their excess can lead to diseases.
It can also be caused by acidosis, where the concentration of the hydrogen ion increases in the intracellular fluid which leads to a large movement of potassium ions toward the extracellular fluid.
Therefore, the condition of acidosis can cause hyperkalemia.

A body was found lying face up in a residence. The body had 4 incised wounds on the trunk centered in the area around the heart and center of the abdomen. The wounds were all about 1.2 inches wide and varied in depth from 4 inches to 6.5 inches. The temperature in the residence was found to be 70° F by both a thermometer and the thermostat setting. The body temperature was measured to be 70°. No rigor mortis was noted in the body. Livor mortis was found on the back and remained dark when pressed. A wound measuring 3 inches by 0.5 inches was found next to a yellow bruise on the eyebrow bone area. Tissue bridges were found in 2 areas of this wound.
Why do you not need to perform the titration while the sample is at its original temperature?
We do not perform the titration while the sample is at its original temperature because reaction is too slow at original temperature and requires high activation energy.
A titration is a method where the concentration of an unknown solution is ascertained by comparing it to a solution of known concentration. The analyte (the unknown solution) is typically added in a known amount to the titrant (the known solution) from a buret until the reaction is finished.
The slow energy step in the reaction process may require a high activation energy, and the proportion of activated molecules needed to reach this reaction at room temperature or original temperature is too low, so most molecules cannot cross this peak. As a result, the reaction at room temperature proceeds very slowly (the final product is not reached). Heat can enhance the proportion of active molecules and catalyse a larger-scale reaction.
