What else can I help you with?
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.
What does an universal indicator tell you about an acid that litmus doesn't?
Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.
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 three tests would you perform to determine what type of minerals are part of the rock?
To determine the types of minerals in a rock, I would perform a hardness test using the Mohs scale to assess scratch resistance. A streak test would reveal the color of the mineral's powder, helping to identify it. Lastly, I would conduct an acid test, applying a dilute hydrochloric acid solution to observe any reaction, which can indicate the presence of carbonates.
What is the presence of lactic acid in gastric juice indicate?
nothing, its a normal component of gastric juice like HCl.
How would you indicate 2 molecules of sulfuric acid?
The would be 2H2SO4
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.
What is litumus paper used to indicate?
litmus paper indicates wether a substance is an acid or a base if it is an acid the paper is turns red, if base it turns blue
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 would you prepare 24-dinitrobenzoic acid from p-nitrotoluene?
The reaction is possible in the presence of sodium dichromate and sulfuric acid.
How does the presence of an acid in water affect the pH of a solution?
The presence of an acid reduces the pH.
What does an universal indicator tell you about an acid that litmus doesn't?
Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.
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.
What color would litmus turn with hydrochloric acid?
Litmus paper would turn red in the presence of hydrochloric acid, indicating acidity.
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?
