250 x 0.2 = V x 11.7
Therefore V = 250 x 0.2 /11.7 = 4.27 say 4.3 ml
so take 4.3 ml of 11.7 M acid and dilute to 250 ml in a volumetric flask, you will get 250 ml of 0.2M HCl.
To determine the limiting reagent in a chemical reaction, compare the amount of each reactant used to the stoichiometry of the balanced equation. The reactant that produces the least amount of product is the limiting reagent because it is fully consumed first, limiting the amount of product that can be formed.
To find the amount of AgCl formed, we first need to calculate the limiting reagent. This is done by converting the given masses of AgNO3 and BaCl2 to moles, determining the mole ratio between them, and then the limiting reagent based on the smaller value. Once the limiting reagent is determined, use the mole ratio from the balanced chemical equation to find the moles of AgCl formed and then convert that to grams.
I'm unable to view or interpret images. However, relative humidity is a measure of the amount of moisture in the air compared to the maximum amount it can hold at a given temperature. It is typically expressed as a percentage.
To make a 6 N solution of ammonium hydroxide, you would mix the appropriate amount of concentrated ammonium hydroxide solution with water to achieve the desired concentration. The specific volumes of each component would depend on the concentration of the concentrated solution you are starting with. It is important to handle ammonium hydroxide with caution due to its caustic nature.
Ammonium hydroxide can be disposed of by diluting it with a large amount of water to reduce its concentration before flushing it down the drain. It should not be mixed with other chemicals or poured down storm drains. It is always best to check local regulations for proper disposal methods.
no it doesn't.dissolving or making a solution of an acid makes a more dilute solution of the acid.
To prepare Seliwanoff's reagent, dissolve resorcinol in concentrated hydrochloric acid, then add a small amount of acetaldehyde. Mix well and dilute with water if needed. This reagent is used for differentiating between aldose and ketose sugars based on the color developed upon heating.

No, the excess reagent does not determine the amount of product formed in a chemical reaction. The amount of product is determined by the limiting reagent, which is the reactant that is completely consumed first. The excess reagent will remain in excess after the reaction is complete.
The amount of product formed will be limited by the amount of the limiting reagent.

A suitable reagent blank for measuring the absorbance of a protein solution mixed with Bradford reagent at 595nm would be a blank containing all components of the reaction except the protein sample, such as water or buffer mixed with the Bradford reagent. This blank will account for any background absorbance contributed by the reagent itself, allowing for a more accurate measurement of the protein concentration.
To determine the limiting reagent in a chemical reaction, compare the amount of each reactant used to the stoichiometry of the balanced equation. The reactant that produces the least amount of product is the limiting reagent because it is fully consumed first, limiting the amount of product that can be formed.
To find the limiting reagent in a chemical reaction, you calculate the amount of product that each reactant can produce. The reactant that produces the least amount of product is the limiting reagent. You can then use this information to determine the amount of product that can be formed in the reaction.
The amountof product form will be limited by the amount of the limiting reagent
