Which of these would indicate that the respiration reactions occurring are anaerobic?
Presence of byproducts such as lactic acid or ethanol, absence of oxygen, lower energy yield compared to aerobic respiration.
How would you prepare 24-dinitrobenzoic acid from p-nitrotoluene?
The reaction is possible in the presence of sodium dichromate and sulfuric acid.
If you have discovered a new virus and have isolated its nucleic acids What feature could you look for to determine if the nucleic acids of this virus are RNA or DNA?
One way to determine if the nucleic acids of the virus are RNA or DNA is to check for the presence of thymine in the nucleic acid sequence. Thymine is only found in DNA, so its presence would indicate that the virus has a DNA genome. Conversely, the presence of uracil instead of thymine would indicate an RNA genome.
What does an universal indicator tell you about an acid that litmus doesn't?
An universal indicator provides a range of colors to indicate the strength of an acid or base, while litmus paper only turns red in the presence of an acid and blue in the presence of a base. This means that an universal indicator can give more detailed information about the acidity or alkalinity of a solution compared to litmus paper.
What turns red in the presence of acid and blue in presence of alkali?
It is Litmus Paper.
What is the presence of lactic acid in gastric juice indicate?
nothing, its a normal component of gastric juice like HCl.
What is litumus paper used to indicate?
Litmus paper is used to indicate whether a substance is acidic or basic. Blue litmus paper turns red in the presence of an acid, while red litmus paper turns blue in the presence of a base.
Which of these would indicate that the respiration reactions occurring are anaerobic?
Presence of byproducts such as lactic acid or ethanol, absence of oxygen, lower energy yield compared to aerobic respiration.
How would you indicate 2 molecules of sulfuric acid?
The would be 2H2SO4
What would happen if you ate hydrochloric acid?
It would very much depend on the strength of the acid, which you do not indicate. Your stomach is already full of hydrochloric.
What symbol would a dilute acid be?
A dilute acid would be represented by the chemical symbol for the specific acid, followed by "(aq)" to indicate that it is in aqueous solution. For example, a dilute solution of hydrochloric acid would be represented as HCl(aq).
How does the presence of an acid in water affect the pH of a solution?
The presence of an acid reduces the pH.
How would you prepare 24-dinitrobenzoic acid from p-nitrotoluene?
The reaction is possible in the presence of sodium dichromate and sulfuric acid.

A substance used to indicate the presence of an acid base or neutral?
An indicator is a substance that changes color in response to the presence of an acid or a base. It helps to determine the acidity or alkalinity of a solution by changing color based on the pH level.
Is hydrochloric acid in stomach acid alkali or neutral?
Hydrochloric acid in stomach acid is an acidic substance, not alkaline or neutral. Stomach acid has a low pH level, usually around 1-3, due to the presence of hydrochloric acid, which aids in digestion by breaking down food and killing bacteria.
