A solution of K2SO4 and KCl is added to a solution of Ba(NO3)2. Which of these compounds will precipitate out of this combined s
Archy [21]

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.

Calculate moles of oxygen atoms in 0.68mol of KMnO4
Dominik [7]
Alright, so that means we have 0.68 mol of the compound


For each 1 mol of the compound, we have 4*1 oxygens (because there are four oxygens in the formula)
Therefore for each 0.68 mol of the compound, we have 4*0.68 moles of oxygen!

What effect does filtration have on water with a ph of 3?
creativ13 [48]

Answer:

None  

Step-by-step explanation:

A high pH is caused by an excess of hydrogen ions over hydroxide ions.

Hydrogen ions are so small that they pass through the pores of an ordinary filter.

Thus, ordinary filtration has no effect on the pH of water.

Using your periodic table, identify element X based on its average atomic mass.
77julia77 [94]

The relative atomic mass of the element is 15.99 and the element is oxygen.

<h3>What is the relative atomic mass of the element?</h3>

Let us note that owing to the fact that elements often have isotopes, the relative atomic mass is not always a whole number. Now we have tp obtain the relative atomic mas from the atomic masses of the elements.

Thus;

X = (15.99 * 0.99762) + (16.999 * 0.00038) + (17.999 * 0.002)

X = 15.95 + 0.0065 + 0.036

X= 15.99

Thus the relative atomic mass of the element is 15.99 and the element is oxygen.
