The mass of solid AgBr that is produced when 100.0 ml of 0.150 M AgNO3 is added to 20.0 ml of 1.00 M NaBr 2.82g.
To find the mass of AgBr formed, first calculate the moles of AgNO3 in 35.5 mL of 0.184 M solution. Then, use the mole ratio from the balanced chemical equation between AgNO3 and AgBr to find the moles of AgBr formed. Finally, multiply the moles of AgBr by its molar mass to get the mass. Note that since HBr is in excess, AgNO3 will be the limiting reagent.

Aqueous means large excess of water. when we write the worf aq with a substance in a chemical reaction it means that the substance formed is dissolved in water. For eg- CaO(s) + H2O(l) -------> Ca(OH)2 (aq)
To address excess problems in stoichiometry, start by determining the limiting reactant based on given quantities. Then calculate the amount of product formed from this limiting reactant. Next, subtract this amount from the excess reactant quantity to find the remaining excess reactant. Finally, determine if there is any new product formed from the excess reactant.
Yes, an acidic solution has an excess of hydrogen ions (H+). This is because acids donate protons (H+) in aqueous solutions, resulting in a higher concentration of hydrogen ions compared to hydroxide ions (OH-) which are found in basic solutions.
Zinc hydroxide dissolves in excess dilute sodium hydroxide because it forms a complex ion, [Zn(OH)4]^2-, which is soluble in aqueous solution. This complex ion helps stabilize the zinc hydroxide and prevents it from precipitating out of solution.
To calculate the pH of the resulting solution when mixing HCl and NaOH, you need to determine the moles of each reactant. Use these values to find the limiting reagent and the excess reagent. Then, calculate the concentration of the excess reagent left in solution. Finally, use the concentrations of the excess reagent and water to determine the pH of the resulting solution.
The white precipitate of silver chloride will dissolve when aqueous ammonia is added.
excess consumption of soft drinks may lead to excess stomach acid.Why? and how is this treated

The precipitate of salicylic acid dissolves in excess sulphuric acid due to the formation of a complex between salicylic acid and sulphuric acid, which increases the solubility of the precipitate. This reaction results in the formation of a colorless solution, as the salicylic acid is converted into its conjugate base form.
You would have to do a count of all the inventory. Have all the managers submit the information so you can determine the excess.
Phlebotomy, or blood removal, has been used with some success. Iron chelation using drugs such as desferrioxamine help patients excrete excess stores of iron.
To address excess problems in stoichiometry, start by determining the limiting reactant based on given quantities. Then calculate the amount of product formed from this limiting reactant. Next, subtract this amount from the excess reactant quantity to find the remaining excess reactant. Finally, determine if there is any new product formed from the excess reactant.
The molar mass of BaSO4 is 233.4 g/mol. From the given data, the number of moles of BaSO4 formed can be calculated as 0.0891 g / 233.4 g/mol = 3.82 x 10^-4 moles. Since 1 mole of BaSO4 contains 1 mole of Ba, the number of moles of Ba in the sample is also 3.82 x 10^-4. The percentage of Ba in the original sample is then (3.82 x 10^-4 moles / molar mass of Ba) x 100%.
These include medicines to help with depression , excess saliva production, sleep disturbances, and constipation
The molar mass of BaSO4 is 233.4 g/mol. Therefore, 0.0891 g of BaSO4 corresponds to 0.000382 moles of BaSO4. Since BaSO4 contains 1 mole of Ba for every 1 mole of BaSO4, the original sample contained 0.000382 moles of Ba. The percentage of barium in the compound is calculated as (mass of Ba / total mass of the compound) * 100, which equals approximately 0.143%.
The three "Ds"--diuretics, digitalis, and diet--are frequently prescribed for medical conditions that result in excess fluid volume.
