What is the formula of lithium nitride? What is the chemical formula of tin IV oxide? What are the symbol formulae of barium oxide, rubidium nitride, and magnesium chloride? What is the formula for barium phosphate? Hypobromite is used to purify contaminated water. What is the formula for hypobromite? What is the formula of sodium sulphate?

What is the formula for mercury II nitride? How do you write a chemical abstract? What is the molecular formula for caproic fatty acid? Are there two times as many hydrogen atoms as oxygen atoms in glycerol?

What is the formula of the compound formed by Ba and F? What is the formula for copper ll phosphate? What salts does calcium form with sulfide dianion, and with hydrogen sulfide anion? How do you write the formula of periodic acid? What is the formula for titanium IV chloride? What is the formula of aluminum phosphate? Aluminum hydroxide is a popular antacid. What is the formula of aluminum hydroxide?

What is the chemical formula for the compound formed between chromium lll and the nitrate ion? What is the formula for electrolytes? Considering the following precipitation reaction: How do you write the formula overall equation, the complete ionic equation, and the net ionic equation for the reaction between aqueous solutions of calcium chloride and silver nitrate?

Given a selection of anions, phosphate, sulfate, nitrate, how do we form salts with cations? If an element has more than one ionic charge, how is that piece of information represented in a chemical name? What is the chemical formula for ammonium tetraborate? Why is this reaction still not balanced?

Am I allowed to multiply the subscripts outside the parenthesis after doing this specific question's criss cross? For the following chemical reaction: What is the chemical formula for an ionic compound of potassium and oxygen?

What is the chemical formula for zinc carbonate? What is the electronic structure of selenium? What salt would it form with chromium metal?

Why must we mention the oxidation state of iron in iron oxide? Is "sodium hydrogen carbonate" the same as "sodium carbonate"? What is the formula for vanadium V phosphate?

What is the formula for manganese Ill fluoride? Its formula mass is 30 amu. What is the molecular formula? In order to produce a single molecule of methane, how many carbon C atoms are needed? What are the names of the following ionic compounds? What net lonic equation can be derived from this complete ionic equation? What is the formula for aluminum fluoride?

I note that these charges balance each other out, and so the final reaction would look like this:. I note that the coefficients do not change because the subscripts did not change. Guided Practice , Part 2: I ask students to do the first practice problem in the Neutralization Practice Problems I sheet.

After they have had a chance to try it, I ask a student to show their work and explain how they derived the chemical formula for the salt, as well as the coefficients. Student Activity , Part 2: I then release students to finish the Neutralization Practice Problems I sheet. I walk around and answer questions and point out mistakes when I see them. The big challenge is around writing the chemical formulas for salts, especially for salts containing polyatomic ions.

I remind students to use the table on page of their text book. To wrap this lesson up I briefly review the second neutralization practice problem. I note that students need to then balance the charge for the salt before they balance the entire chemical equation. I then give each student a ticket to leave that they complete without using any notes. In student work 1, the student did not balance the chemical equation.

In student work 2, the student was able to write the correct answer. In student work 3, there is no evidence of student understanding, as is the case in student work 4. Sign Up Log In.

Mini-lesson and Guided Practice, Part 1. Jot down the name of the non-metal ions. Ammonium is not an element, but occurs when 1 nitrogen ion combines with 4 hydrogen ions. So, you're working with ammonium and sulfate, or ammonium sulfate. Ammonia itself is neutrally charged. Combine the name of the metal with the names of the non-metals. Not Helpful 0 Helpful 2. If you look at the group numbers of non-transition metals, they can tell you charges.

For example, Chlorine Cl is in group 17 7A. If you try that with Group 5,6,7 elements, you will find the pattern -3, -2, -1 for their charges. It gets more complicated if you have polyatomic ions, since the charge determination involves some calculation. Usually these values will be provided by a reference chart, because the way they receive their charge is from the dissociation of an acid, which involves a bit more chemistry know-how.

Not Helpful 4 Helpful Is there any simple method to identify the compound by observing its ionic properties? Not Helpful 7 Helpful If the anion has "-ide" in its name, it has no oxygen atoms. Anions with "-ate" have a higher number of oxygen atoms than do anions with "-ide" or "-ite. Not Helpful 0 Helpful 5. Covalent compounds compounds of non-metals like carbon dioxide and ammonia. Not Helpful 2 Helpful 7.

I am confused about compounds like iron 2,3 oxide - things with both charges. Can you clarify, please? Some metals exist in nature in more than one form. Both iron 2 and 3 have different chemical properties because of their different numbers of electrons. Not Helpful 16 Helpful This is an ionic compound. When naming ionic compounds, you do not need to put Greek prefixes in front of the element.

Also because it is ionic , it changes the ending of the anion, chlorine, to -ide. Not Helpful 7 Helpful 8. Sulfate is any salt or ester made up of sulphuric acid.

Sulfide is used to describe any of three types of chemical compounds that contain sulfur. Sulfite is sulfur dioxide, or SO2.
