One hundred grams of water is saturated with NH CI at
Pepsi [2]

Answer:

  • About 18 g of NH₄Cl will precipitate.

Explanation:

The <em>table G</em> is the graph of the solubility curves for several solutes which is attached.

The second picture identifies the solubilities for the  NH₄Cl at 50ºC and 10ºC.

The solubility of NH₄Cl at 50ºC is about 52 g/ 100 g of water.

The solubility of NH₄Cl at 10ºC is about 34 g / 100 g of water.

Then, at 50ºC 100 g of water saturated with NH₄Cl contains about 52 g of NH₄Cl and 100 g of water saturated with NH₄Cl contains 34 g of NH₄Cl.

The difference, 52g - 34 g of NH₄Cl shall precipitate:

          52 g - 34 g = 18g ← answer

Write a balanced equation for the decomposition reaction described, using the smallest possible integer coefficients. When ammon
MAXImum [283]

Answer:

NH₄Cl  ------> NH₃  +  HCl

Explanation:

Ammonium Chloride =(NH₄Cl

Ammonia = NH₃

Hydrochloric Acid = HCl

NH₄Cl  ------> NH₃  +  HCl

In decomposition reaction, the reactant is breaking down into smaller parts. In this case, all of the coefficients are 1. The reaction is already balanced.

How many molecules are in 5 moles of C10H210?
Pavlova-9 [17]

Answer:

3.0 x 10²⁴molecules

Explanation:

Given parameters:

Number of moles of compound  = 5moles

Unknown:

Number of molecules  = ?

Solution:

A mole is substance that contains the Avogadro's number of particles;

   1 mole  = 6.02 x 10²³ molecules

   5 moles of the compound will give 5 x 6.02 x 10²³ molecules

                = 3.0 x 10²⁴molecules
