Annette [7]

Answer:  The precipitate formed is BaSO_4

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid or precipitated form are represented by (s) after their chemical formulas.  

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.  

The balanced chemical equation is:

K_2SO_4(aq)+BaCl_2(aq)\rightarrow BaSO_4(s)+2KCl(aq)

two solutions are made by mixing sugar and enough water to make a 1 liter solution. one contains 5% sugar and the other contains
Free_Kalibri [48]

Based on their percent concentration, the 5% sugar solution contains more water.

<h3>What is the concertation of a solution?</h3>

The concentration of a solution is the amount of solute dissolved or present in a given volume of solution.

Concentration of solutions can be expressed as either:

  • molar concentration
  • mass concentration
  • percentage concentration

The concentration of the sugar solutions are given as percent concentration.

The 5% sugar solution contains 5% sugar and 95% water

The 10% sugar solution contains 10% sugar and 90% water.

Therefore, the 5% sugar solution contains more water.
