What is name of the polyatomic ion of each compound of KNO3?
The polyatomic ion in KNO3 (potassium nitrate) is NO3- , the nitrate ion. This ion is polyatomic because it contains four atoms bonded together. The nitrate ion is derived from nitric acid, HNO3.
What are four different compounds that contain potassium?
KCl = Potassium Chloride KOH = Potassium Hydroxide KNO3 = Potassium Nitrate KMnO4 = Potassium Permanganate
How many atoms in HCLO2?
There are four atoms in one of these molecules.
What is the correct number of atoms and elements in Potassium Sulphate?
In Potassium Sulphate there are two atoms of potassium, one atom of sulphur and four atoms of oxygen so there are 7 atoms and three elements.
How many mol of potassium are represented by 7.85 x 10 23 potassium atoms?
Four (4) mol of potassium are represented.
In biology which term includes the other four atoms molecules electrons elements and protons?
Molecules Atoms which are elements make up molecules. Protons and electrons make up atoms.
How many carbon atoms in two ethene molecules?
Four: 2x2 = 4 C atoms in 2C2H4 (= two molecules C2H4)
What statement describes the atoms in the molecule with the chemical formula K2SO4?
Two atoms of potassium, one atom of sulfur, four atoms of oxygen
What is the number of atoms in calcium nitrate?
Calcium ions have a charge of +2 and nitrate ions (NO3) have a charge of -1. Because compounds are neutral, you need two nitrate ions to cancel out one calcium ion. Thus the formula for calcium nitrate is Ca(NO3)2. Nitrate has four atoms (one nitrogen and three oxygen). But there are two nitrate ions, so that makes eight atoms. Then you add on the one calcium atom for a total of nineatoms.
How many atoms are in KMnO4?
Six. One atom of Potassium, one atom of Manganese, and four atoms of Oxygen.
How many molecules in 4 H2O2?
There are four molecules.There are sixteen atoms
How much atoms are in 4K3PO4?
1 mole is KNO3 particles. Therefore, 5 moles of KNO3 have 5 x 6.022 x 1023 molecules of KNO3 . Now, 1 molecule of KNO3 has 5 atoms(1 of potassium, 1 of Nitrogen, 3 of oxygen). Therefore, total no. of atoms in 5 moles of KNO3 in KNO3 is 5 x 5 x 6.022 x 1023 =150.55 x 1023 atoms =1.50 x 1025 atoms.
