In which state does the precipitate exist in a precipitation reaction?

Answer: solid.


Explanation:


Precipitate is the solid substance produced during a chemical reaction carried out in a solution.


The precipitate is formed when the reactants in a chemical reaction, which are in solution, form a compound that is insoluble, and so it cannot stand dissolved but precipiates, normally going to the bottom of the vessel, in solid form.


The phases in a chemical equation are indicated using letters inside parenthesis placed to the right of the chemical formula of each compound or element.


These are the common uses: s for solid, aq for aqueous solution, l for liquid, and g for gaseous.


This is an example:


2 NaOH (aq) + CuCl₂ (aq) → 2 NaCl (aq) + Cu (OH)₂ (s)


The phases are:

  • Reactant side: NaOH and CuCl₂ are dissolved in water, which is indicated by the the word aq, meaning aqueous.
  • Product side: NaCl is aqueous, and Cu(OH)₂ is in solid form, meaning that it is a precipitate.

What is the molarity of a solution prepared by dissolving 8 grams of BaCl2 in enough
olga55 [171]

Answer:

Explanation:

molar mass of BaCl2 = 208.23

mol of BaCl2 = 8/208.22

mol of BaCl2 = 0.03841905

Molarity = 0.03841905/0.450

Molarity = 0.085 M

A gold-colored ring has a mass of 17.5 grams and a volume of 0.82 mL. What is the density of this ring?
max2010maxim [7]

Answer:

21 g/mL

Explanation:

To solve this problem, first look at the density equation, which is D=M/V, which D stands for density, M stands for mass, and V stands for volume. When you substitute in the variables, you get D=17.5/.82, which is equivalent to 21.34. However, since we need to pay attention to the sig fig rules for multiplying, we need to have the same amount of sig figs as the value with the least amount of sig figs, which is the number .82. .82 has two sig figs, so you round down. Your answer will be 21 g/mL.

The products of a chemical reaction have different properties than the reactants.
Marta_Voda [28]

Answer:

Explanation:

The products of a chemical reaction have different properties than the reactant because they underwent a chemical change by definition of a chemical reaction. The products are new combinations atoms forming different molecules.
