In ionic equations, the chemicals are written as the ions which are dissolved in water.

AgNO₃(aq) reacts with K₂SO₄(aq) and produces Ag₂SO₄(s) and KNO₃(aq). The balanced complete ionic reaction is
2Ag⁺(aq) + NO₃⁻(aq) +2K⁺(aq) + SO₄²⁻(aq) → Ag₂SO₄(s) +2K⁺(aq) + NO₃⁻(aq)

K⁺(aq) and NO₃⁻(aq) present in both sides. Hence, we can cut off them to find net ionic equation. So, net ionic equation is
2Ag⁺(aq) + SO₄²⁻(aq) → Ag₂SO₄(s)

1 points) You have 300 grams of Al2(CO3)3. How many moles are produced?

Pavlova-9 [17]

Answer:

0.5133805136 moles.

Explanation:

1 gram of Al2(Co3)3 equals 0.0017112683785004 moles, we need the amount of moles produced in 300 grams of Al2(CO3)3, so we have to multiply 1 gram of Al2(CO3)3 times 300: 0.0017112683785004 x 300, in conclusion,

300 grams of Al2(Co3)3 equals 0.5133805136.

All crystals have the same internal arrangement of atoms. a. True b. False

zhenek [66]

B - False. The crystals have the same internal arrangement of atoms in the same species. For example, all crystals of quartz (Onion, Amethyst, Citrine, Smoky) have the same trigonometrical arrangement.

the atoms in salt (NaCl) are arranged in a cubic way.

Which of the following 0.300 M solutions would contain the highest concentration of potassium ions?

mojhsa [17]

Here is a list of 0.300 M solutions that you can consider to select which has the highest concetration of potassium ions:

Select one:

a. potassium oxide

b. potassium phosphate

c. potassium hydrogen carbonate

d. potassium hypochlorite

e. potassium iodide

Answer:

Option b. potassium phosphate

Explanation:

First, you must write the chemical formula of each one of the potasssium compounds. Then, assume all the compounds ionize 100%.

Since all the solutions have the same concentrations, by assuming 100% ionization, the ionization equations will show which one produces the highest number of potassium ions, K⁺¹, and that is the solution with the highest concentration of such ions.

1. Chemical formulae

Compound Formula

a. potassium oxide K₂O

b. potassium phosphate K₃PO₄

c. potassium hydrogen carbonate KHPO₃

d. potassium hypochlorite KClO₄

e. potassium iodide KI

2. Dissociation (ionization):

a. potassium oxide, K₂O

K₂O does not dissociate but react with water to product KOH, then KOH dissociates, but there is not such thing as a 0.300 M solution of K₂O.

b. potassium phosphate:

K₃PO₄ → 3K³⁺ + PO₄¹⁻ 3 K⁺¹ ions per unit formula

c. potassium hydrogen carbonate

KHPO₃ → K⁺¹ + HPO₃⁻¹ 1 K⁺¹ ion per unit formula

d. potassium hypochlorite

KClO₄ → K⁺¹ + HClO₄⁻¹ 1 K⁺¹ ion per unit formula

e. potassium iodide

KI → K⁺¹ + I⁻¹ 1 K⁺¹ ion per unit formula.

Hence, the 0.300 M solution of potasssium phosphate produces the highest concentration of potassium ions.
