A solution of K2SO4 and KCl is added to a solution of Ba(NO3)2. BaS0₄ (s) will precipitate out of this combined solution.
Molecular equation
K2SO4(aq) + Ba(NO3)2(aq) → BaSO4(s) + 2 KNO3(aq)?
This equation represents a double displacement (replacement) reaction, also called a metathesis reaction, in which the reactant ions exchange places to form new products. The general equation is:
A-B + C-D → A-D + C-B;
where A and C are cations, and B and D are anions.
Complete ionic equation: Includes all ions and the precipitate.
2K^+(aq) + SO4^2-(aq) + Ba^2+(aq) + 2[NO3]^-(aq) → 2K^+(aq) + 2[NO3]^- + BaSO4(s)
In an aqueous solution, precipitation is the process of transforming a dissolved substance into an insoluble solid from a super-saturated solution.
The solid formed is called the precipitate. In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant.

A Hydrogen bond will stablish between the protons of the water and the free electron pairs of the electronegative atoms on asparagine, so:
a) can make up to 2 hydrogen bonds, since it has 2 free electron pairs.
b) can make up to 3 hydrogen bonds, since the negative charge makes up for 1 free electron pair aditional to the 2 oxygen already has.
c) can make up to 1 hydrogen bond, since it has 1 free electron pair.
d) since they have no free electron pairs, they cannot establish hydrogen bonds.

H2CO3 represents carbonic acid
Answer:
Everyone, this is Ricky. And today we're working on Problem 51 from Chapter 22 and we're gonna determine the number of UNP. Aired electrons for the complex island of CEO seal for minus two I first up, let's determine the charge of art metal ion. So cue is our charge plus four minus one, which is a charge of each chloride ion. The overall charge of minus two Hugh is equal to plus two. I hope this will help
