£ is not a molecule. It is a currency. That is pounds sterling, used in the U.K.
The balanced equation for the above reaction is as follows;
3NO₂ + H₂O --> 2HNO₃ + NO
stoichiometry of NO₂ to NO is 3:1
molar volume is where 1 mol of any gas occupies a volume of 22.4 L
volume of gas is directly proportional to number of moles of gas.
therefore stoichiometry can be applied for volume as well.
volume ratio of NO₂ to NO is 3:1
volume of NO₂ reacted - 854 L
therefore volume of NO formed - 854 L /3 = 285 L
volume of NO formed - 285 L
The type of cleaning agent that should be used to clean a laminar flow hood is 70% Isopropyl Alcohol.
Isopropyl alcohol is mixed with water for use as a rubbing-alcohol antiseptic. It is also utilized in aftershave creams, hand lotions, and other cosmetics. In enterprise, it is used as a less expensive solvent for cosmetics, drugs, shellacs, and gums, in addition to denaturing ethanol (ethyl alcohol).
Isopropyl alcohol is a colorless, flammable chemical compound with a robust alcoholic smell. As an isopropyl institution related to a hydroxyl group, it's far the handiest example of a secondary alcohol, wherein the alcohol carbon atom is connected to 2 other carbon atoms.
Isopropyl alcohol is pure alcohol and is a colorless liquid with a musty, sharp odor. There are no other components in a bottle of isopropyl alcohol. through assessment, rubbing alcohol consists of isopropyl alcohol among different components, including water. maximum rubbing alcohol manufacturers incorporate 70% isopropyl alcohol.

Answer:
Explanation:
The Law of Conservation of Mass states that mass cannot be created or destroyed.
In terms of a chemical reaction, the mass of the reactants has to equal the mass of the products.
The reactants are A and B. The mass of A is 19 grams and the mass of B is 24 grams. Add the masses.
This is the mass of the reactants.
The products and C and D. The mass of C is 15 grams. The mass of the products has to equal the mass of the reactants, which is 43 grams. Subtract 15 from 43 to find D's mass.
<u>28 grams</u> of D will be produced.
