Give the medical uses of silver nitrate

The rusting of iron is a spontaneous and it's accompanied by a decrease in the entropy of the system(the iron and officer. What can we conclude about the entropy change of surrounding

Use electronic and stability factors to account for the acidity of each hydrogen in

the 3-hydroxybenzoic acid. Label each from increasing to decreasing acidity.

A 0.205 g sample of CaCO3 (Mr = 100.1 g/mol) is added to a flask along with 7.50 mL of 2.00 M HCl.

CaCO3(aq) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)

Enough water is then added to make a 125.0 mL solution. A 10.00 mL aliquot of this solution is taken and titrated with 0.058 M NaOH.

NaOH(aq) + HCl(aq) → H2O(l) + NaCl(aq)

How many mL of NaOH are used?

Ammonium nitrate is produced when ammonia is combined with concentrated nitric acid as shown in the following balanced equation: NH,(aq) + HNO,(aq) — NH,NO)(aq) In an experiment, 404.2 g of ammonium nitrate is produced when 112.5 g of ammonia and excess nitric acid are combined. Determine the percentage yield of the product.

Assuming no change in temperature and pressure, calculate the volume of O₂ (in liters) required for the complete combustion of 17.6 L of butane (C₄H₁₀):

2C₄H₁₀(g) + 13O₂(g) → 8CO₂(g) + 10H₂O(l)

Assuming no change in temperature and pressure, calculate the volume of O₂ (in liters) required for the complete combustion of 17.6 L of butane (C₄H₁₀):

2C₄H₁₀(g) + 13O₂(g) → 8CO₂(g) + 10H₂O(l)

Calculate the amount of water (in grams) that must be added to 15.0 g of sucrose (C12H22O11) to make a solution with a concentration of 7.50 mass %.

Choose three objects in your home that are considered as organic compounds. (whether it is an alkane, alkene, alkyne, alcohol, carboxylic acid, ether, aldehyde, ketone, ester, amine), structure, functional group (group found in homologous series such as hydroxyl [-OH], carboxyl [-COOH], etc.), at least three properties, and other examples of the organic compounds in real life (Note: These other examples must be for each functional group identified). Please answer accurately any 3 basic objects
