Metabolic acidosis would be the result of ketosis. A buildup of ketones in the body that is too great leads to metabolic acidosis.

An excess of acids in the blood can lead to metabolic acidosis. When our kidneys find it difficult to sufficiently eliminate acid from human blood, this occurs.

Because there is an excessive amount of ketone bodies in the blood, ketoacidosis would be a metabolic acidosis with a significant anion gap (keto-anions). The liver releases ketone bodies (acetoacetate, beta-hydroxybutyrate, and acetone) into the blood when the state of the liver's lipid metabolism shifts to one of greater ketogenesis.

In addition to assisting with fat loss, ketosis can reduce your appetite. It also aids in maintaining muscle. Ketosis typically begins to occur in healthy individuals who do not have diabetes and are not pregnant after 3 to 4 days of consuming just under 50 grams of carbohydrates each day.

Therefore, the outcome of ketosis will be Metabolic acidosis

Using the ideal gas law equation and the given information about the volume and molar mass of nitrous oxide, we can calculate the mass of the sample to be approximately 28.6 g.

To answer this question, we need to use the ideal gas law equation: PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature. At STP, the pressure is 1 atm and the temperature is 273 K. We know that the volume of the nitrous oxide sample is 16.5 L, and the molar mass of N2O is 44.013 g/mol.
First, we need to find the number of moles of N2O using the equation: n = PV/RT. Plugging in the values, we get: n = (1 atm)(16.5 L)/(0.0821 L•atm/mol•K)(273 K) = 0.6666... mol.
Next, we can find the mass of the sample by multiplying the number of moles by the molar mass: mass = n x molar mass = 0.6666... mol x 44.013 g/mol = 29.341 g.
Therefore, the answer is closest to c. 28.6 g. It's important to note that we need to round our answer to the correct number of significant figures, which in this case is three.

Using significant figures 0.00296 moles of helium can be calculated to be contained in the balloon.

You might have learnt in school that at STP (Standard Temperature and Pressure), the temperature is 273.15 K and the pressure is 1 atm. The molar volume of any given gas at STP will always be 22.4 L/mol. This will perhaps be known to you as Avogadro's Law.

You are having 75.000 mL of helium, which is 0.075 L. To find the number of moles of helium, you will make use of the ideal gas law:

PV = nRT

The notations are commonly known as P for pressure, V for volume, n is for number of moles, R for gas constant, and T for temperature in Kelvin scale.

At STP, P = 1 atm and T = 273.15 K. The gas constant R is 0.08206 L·atm/mol·K.

So you will then have:

n = PV/RT = (1 atm)(0.075000 L)/(0.08206 L·atm/mol·K)(273.15 K)

n = 0.00296 mol

Using significant figures, you can then round this to three significant figures:

n = 0.00296 mol

The numbre of moles is 0.00296. This is your final answer.

   Percent composition of H: (8 x 1.01 g/mol) / 96.09 g/mol x 100% = 8.41%

   Percent composition of C: 12.01 g/mol / 96.09 g/mol x 100% = 12.50%

   Percent composition of O: (3 x 16.00 g/mol) / 96.09 g/mol x 100% = 50.95%

Therefore, the correct percent composition for (NH4)2CO3 is:

   N = 29.14%

   H = 8.41%

   C = 12.50%

   O = 50.95%

At the end of glycolysis, one can find the energy that was contained in the chemical bonds of glucose in ATP, NADH and pyruvate molecule.

The process of glycolysis takes place in the cytosol of a cell. It can be broken down into two phases viz. energy requiring phase and energy releasing phase.

Energy requiring phase: The starting molecule i.e glucose is at first rearranged and two phosphate groups are attatched to it, which comes from ATP.  The phosphate groups form the sugar- fructose-1,6-biphosphate. This splits into three-carbon sugars

Energy releasing phase: The three carbon-sugars are converted into three-carbon molecules i.e two ATP molecules and one NADH molecule and pyruvate.

Thus, in ATP, NADH and pyruvate we can find the energy contained in chemical bonds of glucose.

The best option to be a recrystallization solvent for sodium benzoate is water. Recrystallization is a purification technique that involves dissolving an impure sample in a solvent and then allowing the solute to slowly crystallize out of the solution under controlled conditions. The pure crystals can be separated from the remaining liquid through filtration.

The most effective solvent for recrystallization is one in which the compound is only slightly soluble at low temperatures but very soluble at high temperatures. By dissolving the compound in a hot solvent and then allowing the solvent to cool, the compound will slowly crystallize out of the solution while any impurities remain dissolved. These impurities are then removed by filtration.

Benzene is no longer used as a solvent because of its toxicity. Ethanol is not the best solvent for recrystallizing sodium benzoate, as it does not have a large enough temperature range to allow for sufficient crystallization and purity. Hexane is non-polar, whereas sodium benzoate is polar, making it ineffective as a solvent for recrystallization. Therefore, the best option to be a recrystallization solvent for sodium benzoate is water.

The theoretical yield of triphenylmethanol is: 1.028 g and the percent yield is: 20.9%.

To calculate the theoretical and percent yields of the reaction between benzophenone and triphenylmethanol, given that benzophenone is the limiting reagent, follow these steps:

1. Calculate the moles of benzophenone:
moles = mass (g) / molar mass (g/mol)
moles = 0.72 g / 182.217 g/mol
moles = 0.00395 mol benzophenone

2. Assume a 1:1 molar ratio between benzophenone and triphenylmethanol. The moles of triphenylmethanol produced will be the same as the moles of benzophenone.

3. Calculate the theoretical mass of triphenylmethanol produced:
molar mass of triphenylmethanol = 260.33 g/mol (you will need to look this up or calculate it from its molecular formula)
mass (g) = moles × molar mass (g/mol)
mass = 0.00395 mol × 260.33 g/mol
mass = 1.028 g (theoretical yield)

4. Calculate the percent yield:
percent yield = (actual yield / theoretical yield) × 100
percent yield = (0.215 g / 1.028 g) × 100
percent yield = 20.9%

Explanation:

The compound is named 2,3-dibromo-2,4-hexadienedioic acid, which consists of a six-membered ring with alternating single and double bonds.

The line-angle formula describes a six-membered ring with alternating single and double bonds. To name the compound, we need to consider the functional groups and substituents present.

The carboxylic acid group, -COOH, is attached to the first vertex of the ring. This group is named as "hexanedioic acid" because it contains six carbon atoms in a linear chain. The prefix "hexa-" indicates the presence of six carbons, and the suffix "-dioic acid" denotes the presence of two carboxylic acid groups.

The bromine atom, represented by "Br," is attached to the third vertex in a clockwise direction. Since there are two bromine atoms present, the prefix "di-" is used. Thus, the compound is named "dibromo-hexanedioic acid."

To specify the positions of the bromine atoms, we start numbering the ring from the vertex where the carboxylic acid group is attached, which is the first vertex. Moving clockwise, the second vertex has a double bond, the third vertex has a bromine atom, and the fourth vertex has a double bond. Therefore, the compound is named as "2,3-dibromo-2,4-hexadienedioic acid." The numbers indicate the positions of the substituents in the ring.

In summary, the compound is named 2,3-dibromo-2,4-hexadienedioic acid, which represents a six-membered ring with alternating single and double bonds, a carboxylic acid group attached to the first vertex, and a bromine atom attached to the third vertex in a clockwise direction.

The weight of magnesium chloride required to prepare the 200 ml solution that is 5.0 M is approximately 48 grams.

To calculate the weight of magnesium chloride (\(MgCl_{2}\)) required to prepare a 200 ml solution that is 5.0 M, we need to use the formula: Weight (in grams) = Volume (in liters) × Concentration (in moles/liter) × Molecular Weight (in grams/mole)

First, we convert the volume from milliliters to liters by dividing it by 1000: Volume = 200 ml ÷ 1000 = 0.2 L. Next, we multiply the volume, concentration, and molecular weight: Weight = 0.2 L × 5.0 mol/L × 95.3 g/mol = 47.65 grams

Rounding to the nearest whole number, the weight of magnesium chloride required to prepare the 200 ml solution that is 5.0 M is approximately 48 grams.

This calculation ensures that the desired concentration is achieved by accurately measuring the appropriate amount of magnesium chloride, taking into account its molecular weight and the desired volume of the solution.

Answer:

Explanation:

C + O2 → CO2

Mole of C = 24 g/(12 g/mole)

Mole of C = 2 mole

Mole of molecular O2 = 74 g/(32 g/mole)

Mole of molecular O2 = 2.3125 mole

Since mole of C < mole of O2, then C being the limiting reagent.

From the reaction, it shows that mole ratio between C and O2 = 1 : 1.

So, 2 moles of C will stoichiometrically react with 2 moles of O2 to generate 2 moles of CO2.

Avogadro's law states that :"equal volumes of all gases, at the same temperature and pressure, have the same number of molecules i.e. 6.02 x 10^23 molecules/mole.

Therefore, 2 moles of CO2 contain 2 moles x 6.02 x 10^23 molecules/mole = 1.204 x 10^24 molecules of CO2 is formed.
