What element is Mg(No3)2?
Mg(NO3)2 {note correct case for "O"} is not an element at all. Instead it is a compound of three elements, magnesium, nitrogen, and oxygen.
What is the correct number of atoms of each element in the formula Mg(NO3)2?
In the formula Mg(NO3)2, there is 1 magnesium atom, 2 nitrogen atoms, and 6 oxygen atoms.
How do you Balance Pb(No3)2 and KI?
The balanced chemical equation for the reaction between lead (II) nitrate (Pb(NO3)2) and potassium iodide (KI) is: Pb(NO3)2 + 2KI -> PbI2 + 2KNO3 This equation is already balanced as it has the same number of atoms of each element on both sides of the reaction arrow.
What is the percent by mass of oxygen in Cr(NO3)3?
To calculate the percent by mass of oxygen in Cr(NO3)3, we need to consider the molar mass of each element. Cr(NO3)3 consists of one chromium atom, three nitrogen atoms, and nine oxygen atoms. The molar mass of Cr(NO3)3 is 274.06 g/mol. The molar mass of just the oxygen atoms in Cr(NO3)3 is 144.00 g/mol. Therefore, the percent by mass of oxygen in Cr(NO3)3 can be calculated as (144.00 g/mol / 274.06 g/mol) x 100%.
What is the product in the element Zn(NO3)2 NaOH --?
The products in the reaction of Zn(NO3)2 with 2 NaOH are Zn(OH)2(s) and 2 NaNO3 . There are no 'elements' involved
