This formula is CaCl2.7 H2O
The equivalent weight of zinc sulfate hepta-hydrate is the molecular weight divided by the number of positive or negative charges contributed by its formula unit in a reaction. For zinc sulfate hepta-hydrate, the molecular weight is 287.56 g/mol and it has a divalent zinc atom which contributes two positive charges, so the equivalent weight would be 287.56/2 = 143.78 g/mol.
Iodine Heptafluoride
hepta or hept-
The prefix for seven atoms of the same element is "hepta-". So a molecule with seven atoms of the same element would be described as "heptatomic".
ZnCO3(s)+H2SO4(aq) --> CO2(g) + H2O (l) + ZnSO4(aq) Acid + metal carbonate = salt + water + carbon dioxide.
The formula for diphosphorus hepta chloride is P2Cl7. It is composed of two phosphorus atoms and seven chlorine atoms.
cobalt sulphate hepta hydrate
The correct chemical formula for hepta boron triiodide is B7I3.
The equivalent weight of zinc sulfate hepta-hydrate is the molecular weight divided by the number of positive or negative charges contributed by its formula unit in a reaction. For zinc sulfate hepta-hydrate, the molecular weight is 287.56 g/mol and it has a divalent zinc atom which contributes two positive charges, so the equivalent weight would be 287.56/2 = 143.78 g/mol.
Iodine Heptafluoride
The prefix hepta- means seven.
If there is 1 molecule of H2O present in a hydrate, the prefix mono- will be used in the name. For example, if there is one water molecule in CuSO4·H2O, it would be called copper(II) sulfate monohydrate.
hepta or hept-
6 and 7 respectively
There are several words that begin with hepta. Some of these include heptachlor, heptad, heptagon, heptarchy, heptameter, heptarch, and heptane.
Heptagon
