This compound is call Nickel sulfate NiSO4
Oxygen is a chemical element with the symbol O and atomic number of 8. Its percentage composition in the compound NiSO4 x 7H2O is 31.3%.
nickel (ll) sulfate heptahydrate
The compound NiSO4·7H2O consists of one NiSO4 molecule and seven water molecules. The percentage of water can be calculated by dividing the molar mass of water by the molar mass of the whole compound, and then multiplying by 100. This results in about 37.2% water in NiSO4·7H2O.
No, precipitation will not occur when NaNO3 and NiSO4 are mixed because neither compound forms an insoluble precipitate with the other. Both NaNO3 and NiSO4 are soluble in water.
The compound NiSO4 7H2O is magnesium sulfate heptahydrate. It is a type of inorganic salt that is commonly known as Epsom salt.
Nickel(II) Sulfate Hexahydrate
No, NiSO4 is not covalent. It is an ionic compound because it is composed of a metal, nickel(Ni), and non-metal, sulfur(S) and oxygen(O). Ionic compounds are formed through the transfer of electrons between the metal and non-metal atoms.
The reaction between zinc (Zn) and nickel(II) sulfate (NiSO4) would result in a displacement reaction where zinc atoms replace nickel in the compound, forming zinc sulfate (ZnSO4) and nickel metal (Ni). The balanced chemical equation is: Zn + NiSO4 → ZnSO4 + Ni.
To determine the grams of NiSO4 in 100 grams of the hydrate, you need to know the percentage of NiSO4 in the hydrate. Once you have the percentage, you can calculate the grams of NiSO4 using the formula: (percentage of NiSO4/100) x 100 grams of hydrate.
To calculate the mass of 0.00844 mol of NiSO4, you need to know the molar mass of NiSO4. It is 154.756 g/mol. So, multiply the number of moles (0.00844) by the molar mass (154.756 g/mol) to get the mass in grams, which is approximately 1.30 grams of NiSO4.
The correct formula of nickel sulfate is NiSO4.
