Why do you need to balance the numbers in an ionic compound what does this do?
Balancing numbers in an ionic compound is necessary to ensure that the compound has a neutral overall charge. This is because the compound should have an equal number of positive and negative charges to be electrically neutral. Balancing ensures that the compound follows the law of conservation of charge.
How do you determine the charge of a multivalent metal in a compound?
To determine the charge of a multivalent metal in a compound, you first need to consider the overall charge of the compound and the charges of the other ions present. For example, if the compound is neutral, the sum of the charges must equal zero. By knowing the charge of the non-metal or polyatomic ion, you can calculate the metal's charge by balancing the total charge in the compound. Additionally, the metal's oxidation state can often be inferred from the compound's name or by using common oxidation states for that particular metal.
Do journal names need to be italicized in academic writing?
Yes, journal names should be italicized in academic writing to indicate that they are titles of publications.
What factors do you need to consider in writing the formula of a compound?
When writing the formula of a compound, you need to consider the charges on the ions involved, ensuring they balance to maintain electrical neutrality. You also need to determine the ratio of each element present in the compound based on the lowest common multiple of the charges. Finally, simplify the ratio if necessary to represent the compound with the smallest whole numbers.
How are formula written for ternary ionic compound given their names?
To write the formula for a ternary ionic compound given its name, you need to determine the charges of the ions involved. The total positive charge from the cations must equal the total negative charge from the anions to create a neutral compound. Use the criss-cross method by swapping the numerical charges to become subscripts. Be sure to simplify the ratio of ions to its lowest whole numbers.
What is the charge on si4o10?
The charge on Si4O10 is zero. The compound is neutral because the total positive charge from the silicon atoms (Si4+) balances out the total negative charge from the oxygen atoms (O10-). So, no need to fret about any extra charges floating around in this molecule.
When writing an autobiography can people still living have their names used?
Yes, but you need permission from them to use it.
What is the empirical formula of the ionic compound formed by Ca2 and Br?
The empirical formula is CaBr2. This is because calcium has a 2+ charge (Ca2+) and bromine has a 1- charge (Br-), so the compound would need two bromine ions to balance the charge of one calcium ion.
Can a doctor charge for a prescription?
Yes, a doctor can charge for writing a prescription. They don't just write them, they have to evaluate whether the individual needs, or continues to need the medication.
How do you write the formula of a compound using stock system?
To write the chemical formula of a compound using the Stock system, you need to indicate the charge of each element using Roman numerals in parentheses after the element symbol. For example, iron(III) chloride would be written as FeCl3, where Fe has a +3 charge and Cl has a -1 charge. Be sure to balance the charges to create a neutral compound.
The ions Cr3 plus and O2- combine to form the ionic compound chromium oxide. In what proportions do these ions combine to produce a neutral compound?
The Cr3+ ion has a +3 charge, while the O2- ion has a -2 charge. To form a neutral compound, we need two O2- ions to balance the charge of one Cr3+ ion. Therefore, the ions combine in a 1:2 ratio to produce the ionic compound chromium oxide (Cr2O3).
What is the formula for the ionic compound rb and br?
Fe (III) has a charge of 3+. Br has a charge of 1-. This means that in order to make the overall charge of the ionic compound of Iron III and Bromine, there must be one atom of Iron III and three atoms of Bromine. This makes the formula FeBr3.
