What mass of silver chloride can be produced from 1.75L of a 0.293M solution of silver nitrate?
To determine the mass of silver chloride produced, we need to know the balanced chemical equation for the reaction between silver nitrate (AgNO3) and sodium chloride (NaCl) that produces silver chloride (AgCl) as a precipitate. Once we have the balanced equation, we can use the stoichiometry of the reaction to determine the number of moles of AgCl produced, and then convert that to mass using the molar mass of AgCl.
There is a plenty of salt deposit composed of Magnesium Chloride Calcium Chloride Magnesium Bromide and brine How can you separate magnesium chloride from calcium chloride after separating sodium?
Using fractional recrystallization.
What reagents may be used for the preparation of acetanilide?
Acetanilide can be prepared using aniline and acetic anhydride as reagents. The reaction typically requires the presence of a catalyst, such as zinc chloride, to facilitate the acetylation of aniline to form acetanilide. The reaction is usually carried out in the presence of a base, like sodium acetate, to neutralize the acidic byproduct formed during the reaction.
NAME THE COMpound using the stock system nal?
Sodium chloride, which is commonly known as table salt, is an ionic compound that can be named using the stock system as sodium(I) chloride.
What is balanced equation for reaction which methane obtained by reduction of chloroform?
The balanced equation for the reaction where methane is obtained by the reduction of chloroform is: 2CHCl3 + 6Zn -> 2CH4 + 6ZnCl2. This reaction involves the reduction of chloroform (CHCl3) using zinc (Zn) metal to produce methane (CH4) and zinc chloride (ZnCl2).

What is the equivalent weight of K2Cr2O7 fully explanation?
The equivalent weight of K2Cr2O7 is determined by the number of moles of electrons transferred in a redox reaction per mole of the substance. For K2Cr2O7, the equivalent weight is calculated using the total change in oxidation state divided by the number of moles of K2Cr2O7 involved in the reaction. This value is used to quantify the amount of K2Cr2O7 needed to gain or lose an equivalent amount of electrons in a redox reaction.
How prepare 0.1 n k2cr2o7?
To prepare a 0.1 N solution of K2Cr2O7 (potassium dichromate), you would need to dissolve 4.903 grams of K2Cr2O7 in enough water to make 1 liter of solution. Weigh out the exact amount of K2Cr2O7 using a balance, then dissolve it in water and make up the volume to 1 liter. This will give you a 0.1 N solution of K2Cr2O7.
.0306 mol of barium hydroxide are added to a 5.00 M solution of hydrochloric acid in a neutralization reaction that produces water and barium chloride How many grams of barium chloride mw equals 208.2?
First, calculate the moles of HCl in the reaction using the volume and molarity provided. Since it is a 1:1 neutralization reaction, the moles of Ba(OH)2 are equal to the moles of HCl. Next, calculate the mass of barium chloride using the molar mass provided and the moles of BaCl2 produced in the reaction.
How amonia gas is prepared?
Laboratory preparation of ammonia or NH3 requires using ammonium chloride and calcium hydroxide. The reaction equation is 2NH4Cl plus CaOH2 gives the products 2NH3 plus CaCl2 plus 2H2O. The ammonium chloride and calcium hydroxide are heated for this reaction.
Sodium chloride can cause allergic reaction?
Using sodium chloride as condiment and preservative in reasonable amounts (2-5 g/day) doesn't cause an allergy; but the sensitivity of peoples to NaCl is different.
How many grams of potassium are in 24.1 g of K2Cr2O7?
To find the amount of potassium in K2Cr2O7, we need to determine the molar mass of K2Cr2O7 and the molar mass of potassium. Molar mass of K2Cr2O7 = (239.10 g/mol) + (252.00 g/mol) + (7*16.00 g/mol) = 294.18 g/mol Molar mass of potassium = 39.10 g/mol Now, determine the amount of potassium in 24.1 g of K2Cr2O7 by first converting 24.1 g of K2Cr2O7 to moles, then calculating the grams of potassium is in that amount of K2Cr2O7 using the molar ratios determined by the chemical formula.
What mass of silver chloride can be produced from 1.99 L of a 0.104 M solution of silver nitrate?
To calculate the mass of silver chloride produced, we need to use the concept of stoichiometry. Firstly, write the balanced chemical equation for the reaction between silver nitrate and sodium chloride. Then, use the molarity of silver nitrate and the stoichiometry of the reaction to find the moles of silver chloride produced. Finally, convert the moles of silver chloride to grams using its molar mass.

How do you convert benzaldehyde to benzoyl chloride?
Benzaldehyde can be converted to benzoyl chloride by reacting with thionyl chloride (SOCl2) under reflux conditions. The reaction involves replacement of the aldehyde group with a chlorine atom to form the benzoyl chloride. Attention must be paid as thionyl chloride is a corrosive and toxic compound, so the reaction should be performed in a fume hood and with appropriate safety precautions.
How many potassium atoms are there in a sample of K2Cr2O7 having a mass of 24.43 g?
To find the number of potassium atoms in a sample of K2Cr2O7, you first need to calculate the number of moles of K2Cr2O7 using its molar mass. Then, you can determine the number of moles of potassium atoms since there are 2 potassium atoms in each molecule of K2Cr2O7. Finally, use Avogadro's number (6.022 x 10^23) to convert the number of moles of potassium atoms to the actual number of atoms.
What is the mechanism of synthesis of fluorescein by using pthalic anhydride resorcinol and zinc chloride?
Fluorescein is synthesized by heating phthalic anhydride and resorcinol in the presence of zinc chloride catalyst. The reaction involves the condensation of one molecule of phthalic anhydride and two molecules of resorcinol to form fluorescein. Zinc chloride acts as a Lewis acid catalyst, facilitating the reaction by promoting the dehydration and cyclization steps.
