How many atoms are in the compound KCI?
two elements and two atoms (potassium and chlorine)In one molecule of KCl, there are two elements (potassium and chlorine).The molecular weight of KCl is 74.55 g / mol.So, 74.55 g of KCl will contain 6.023 x 1023 molecules or 12.046 x 1023 atoms.
How many potassium atoms and oxygen atoms are in a binary compound?
The number of potassium and oxygen atoms in a binary compound depends on the specific compound. For example, in potassium oxide (K2O), there are 2 potassium atoms and 1 oxygen atom. In potassium chloride (KCl), there is 1 potassium atom and 1 chlorine atom.
How many elements are there n KCl?
In KCl, there are two elements: potassium (K) and chlorine (Cl).
What is needed to balance the reaction Cl2 plus KI KCl plus I2?
To balance the reaction Cl2 + KI -> KCl + I2, you just need to place a coefficient of 2 in front of KCl to balance the number of chlorine atoms on both sides of the reaction. The balanced reaction is Cl2 + 2KI -> 2KCl + I2.
How many moles of KCl are contained in 1.9L of a 0.90M KCl solution three significant figures please?
The number of moles of KCl can be calculated by multiplying the volume of the solution in liters by the molarity of KCl. This results in 1.9 L * 0.90 mol/L = 1.71 mol of KCl in 1.9 L of a 0.90 M KCl solution.

How many atoms of K in 2.77g of KCl?
To find the number of K atoms in KCl, we first calculate the molar mass of KCl: 39.10 (K) + 35.45 (Cl) = 74.55 g/mol. Next, we determine the number of moles of KCl in 2.77g: 2.77g / 74.55 g/mol = 0.0371 mol. Since there is 1 K atom in 1 KCl molecule, the number of K atoms in 2.77g of KCl is the same as the number of moles of KCl, which is 0.0371 mol.
How many particles does potassium chloride have?

How many moles of KCl in 0.90M KCl?
The answer is of course 0,9 M.
How many moles of KCl are contained in 1.7L of a 0.83M KCl solution?
moles KCL = ( M solution ) ( L of solution )moles KCl = ( 0.83 mol KCl / L ) ( 1.7 L ) = 1.41 moles KCl
How many moles of KCl are contained in 0.635L of 2.2M KCl?
moles KCl = ( M solution ) ( V solution in L )moles KCl = ( 2.2 mol KCl / L solution ) ( 0.635 L of solution )moles KCl = 1.397 moles KCl
What kind of crystalline solid is KCl?
An Ionic Solid.Ionic solid
What attractive forces exist between H2O and KCl?
The attractive forces between H2O and KCl include ion-dipole interactions, where the positively charged hydrogen atoms in water are attracted to the negatively charged chloride ions in KCl, and dipole-dipole interactions, where the negative oxygen atom in water is attracted to the positive potassium ion in KCl. These interactions lead to the dissolution of KCl in water.
