How do you calculate number of ions in 30 g of BaCl2?
To calculate the number of ions in 30 g of BaCl2, first determine the molar mass of BaCl2 which is 137.33 g/mol. Next, calculate the number of moles in 30 g by dividing the mass by the molar mass. Since BaCl2 dissociates into 3 ions (1 Ba2+ and 2 Cl-) for every formula unit, you can multiply the number of moles by 3 to find the total number of ions.
What is the coordination number of both ions in the cesium chloride crystal?
In cesium chloride crystal, cesium ions have a coordination number of 8, as they are surrounded by 8 chloride ions. On the other hand, chloride ions have a coordination number of 8, as they are surrounded by 8 cesium ions.
How many moles of ions are present in aqueous solutions prepared by dissolving 10.00g of the f scandium III bromide in water to make a 1.25 L solution?
First figure out the formula of Scandium(III) Bromide: its ScBr3. Next ignore the 1.25 L solution part -- it's just extra information. Use the 10.00g to convert it to moles. To do so first figure out the molar mass of ScBr3: its 285g/mol. Now you do: 10.00g x 1 mol/285g = .0350877193... mol. Next round it to 3 significant figures: .0351. Now you find out the number of ions in the formula and use it as a conversion factor (instead of Avagrado's number, 6.02 x 1023): it has 4 ions (Scandium = 1; Bromide = 3). Finally you do: .0351 mol x 4 mol ions/1 mol = .1404 mol ions. This is your answer! By Geovonni Bell ;-)
How do you write charges on ions?
To write charges on ions, you need to determine the number of electrons gained or lost by the ion. If an ion gains electrons, it becomes negatively charged, and if it loses electrons, it becomes positively charged. The charge is then written as a superscript next to the ion symbol.
What is meant by number of replaceable ions?
The number of replaceable ions refers to the total number of ions in a compound that can be exchanged or replaced with other ions through a chemical reaction or process, such as ion exchange or precipitation. This value is important in understanding the reactivity and behavior of the compound in different environments.
What does the number next the isotope signify?
The number next to the isotope is the mass number- They all have different masses because they have different numbers of neutrons, but the same amount of protons (Remember protons + nuetrons = mass)
