Write the reduction reaction of glucose to form sorbitol. List and explain the side effects caused by too much sorbitol consumption.
Answer:
The product of reduction of glucose is sorbitol
The side effects caused by too much sorbitol consumption include: Diarrhea, Nausea, stomach discomfort
Explanation:
Please find attached the reaction of glucose with NADPH to produce sorbitol
Answer:
Glycytols or alditols (also called alcoholic sugars) are characterized by being a set of sweet-tasting organic chemical compounds of the polyol family. These compounds are chemically considered hydrogenated carbohydrates whose carbonyl group (aldehyde, ketone, sugar reducer) has been reduced to a primary or secondary hydroxyl group (i.e. an alcohol). Alcoholic sugars have the general formula H (HCHO) n + 1H, while sugars have H (HCHO) nHCO. Food applications are used in modifications as sweeteners to replace sugar (sucrose). Glycytols contain very low calorie contents, and their low fermentability makes them non-cariogenic, that is why it can be found in the package leaflet of some pediatric toothpastes, or Asian chewing gum itself.
Explanation:
When taking too much sorbitol (between 20 to 50 grams) it can have many negative effects by causing gas and abdominal pain and even become a very powerful laxative that even causes diarrhea.
In diabetic patients, it is usually used as a sweetener and prevents spikes in blood glucose because it generates the accumulation of water in the walls of the intestines, delaying the absorption of glucose

Write the balanced COMPLETE ionic equation for the reaction when Na₂CO₃ and AgNO₃ are mixed in aqueous solution. If no reaction occurs, write only NR.
Final answer:
The balanced complete ionic equation for the reaction between Na₂CO₃ and AgNO₃ in aqueous solution is 2Na+ + 2NO₃- + CO₃²- + 2Ag+ → 2Na+ + 2NO₃- + Ag₂CO₃. The sodium and nitrate ions can be eliminated from the equation since they appear unchanged on both sides. The net ionic equation is CO₃²- + 2Ag+ → Ag₂CO₃.
Explanation:
Balanced Complete Ionic Equation:
2Na+(aq) + 2NO3-(aq) + CO32-(aq) + 2Ag+(aq) → 2Na+(aq) + 2NO3-(aq) + Ag2CO3(s)
In this reaction, the sodium ion (Na+) and the nitrate ion (NO3-) appear unchanged on both sides of the equation, so they can be eliminated from the reaction.
Net ionic equation:
CO32-(aq) + 2Ag+(aq) → Ag2CO3(s)

What state of matter has the strongest intermolecular forces?
A) solid
B) none of these choices
C) liquid
D) gas
Answer:
Solid
Explanation:
As the temperature continues to drop, the matter forms a solid. Due to the solid's low kinetic energy, particles have no "time" to move around, the particles have more "time" to be attracted. Therefore, solids have the strongest intramolecular forces (because they have the strongest attraction).

Elements with an oxidation number of one include which of the following
The answer is C. Potassium and D. Lithium.
The correct answers to which elements have an oxidation number of 1 are C. Potassium and D. Lithium, as both are group 1 alkali metals that typically form ions with a +1 charge.
Both potassium and lithium belong to the group 1 elements of the periodic table, also known as the alkali metals. These metals typically have a +1 oxidation state when forming compounds. Potassium (K) for example, readily loses one electron to form a K+ ion, also known as a monovalent cation. Similarly, lithium (Li) will also lose one electron to form an oxidation state of +1.
Magnesium (Mg) and Calcium (Ca), on the other hand, form ions with a 2+ charge, indicating an oxidation state of +2. For instance, in [tex]MgCl_2[/tex], magnesium has an oxidation number of +2. Therefore, options A. Magnesium and B. Calcium do not have an oxidation number of 1 and are not correct answers to the question.
What groups of elements do not have a charge and why
Answer:
Noble gases because they have a full outer shell of electrons.
Explanation:
Noble gases usually called inert gases are generally non reactive gases. They belong to group 18 elements.They tend to not gain the electron or not give up a electron as they have full valence shells. Because they already have full valence shell and therefore full outer energy level, they are very stable and hardly react with any other elements.
If 27.9 grams of calcium carbonate reacts with excess HCl, how many moles of calcium chloride are produced
Answer:
[tex]\large \boxed{\text{0.2797 mol}}[/tex]

a solid sample of oil is warmed until it turns into a liquid. which property of the oil will decrease?
I think the answer is it turnes into a gas. Hope it helps! :) Asnwer is density.
A solid sample of oil is warmed until it turns into a liquid. Density is the property of the oil will decrease.
What do you mean by density ?Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume. Density Symbol: D or ρ Density Formula: ρ = m/V, where ρ is the density, m is the mass of the object and V is the volume of the object.
As temperatures rose, the density of all oils decreased. The temperature coefficients of density change differed slightly between oils. The density differentials between oil and water, as well as their temperature coefficients, varied significantly between oils.
Oil is denser than alcohol but denser than water. Because the molecules that make up oil are larger than those that make up water, they cannot pack as tightly as water molecules can. They occupy more space per unit area and have a lower density.
Thus, Density is the property of the oil will decrease.

Baking Soda Acidic, alkaline, or neutral?*
O
Acidic
Alkaline
Neutral
Answer:
Baking soda, also known as sodium bicarbonate, is a base
Baking soda, or sodium bicarbonate, is an alkaline substance with a pH greater than 7, indicating its basic properties. It reacts with acids in baking to produce carbon dioxide, helping the dough to rise. The correct answer is B) Alkaline.
Sodium bicarbonate, commonly known as baking soda, is a chemical compound with the formula [tex]NaHCO_3[/tex]. It is a white solid that is crystalline but often appears as a fine powder. Baking soda is not neutral or acidic; it has alkaline properties.
When baking soda is dissolved in water, it slightly raises the pH of the solution, making it basic. The pH scale, which measures how acidic or alkaline a substance is, typically ranges from 0 (very acidic) to 14 (very alkaline), with 7 being neutral. Sodium bicarbonate usually has a pH greater than 7; therefore, it can help neutralize acids.
When used in baking, baking soda acts as a base and usually reacts with an acidic ingredient (like lemon juice or buttermilk).
This reaction produces carbon dioxide gas, which causes dough or batter to expand and "rise," giving baked goods their porous texture. The equation for its reaction with an acid is as follows: [tex]NaHCO_3(s) + H^+[/tex] → [tex]Na^+ + H_2O + CO_2[/tex]. This demonstrates baking soda’s role as a base in neutralizing acids and producing carbon dioxide and water.
