What is the compound name of MgNO32?
The compound name for Mg(NO3)2 is magnesium nitrate.
What is the following redox reaction classifed as Mg plus 2AgNO3 equals MgNO32 plus 2Ag?
This is a 'Sngle Displacement' reaction ( A + BC --> AC + B
Is MgNO32 soluble in water?
Mg(NO3)2 is soluble in water because nitrate (NO3-) salts are generally soluble, including magnesium nitrate.
What is the concentration of nitrate ions in a 0.25 M MgNO32 solution?
Since Mg(NO3)2 dissociates into Mg^2+ ions and NO3^- ions in solution, the concentration of nitrate ions in a 0.25 M Mg(NO3)2 solution will also be 0.25 M.
What are the elements in MgNO32?
Since you already have the chemical formula of the compound, it is not difficult to make up what elements it is made up from. The elements are magnesium (Mg), nitrogen (N) and oxygen (O). The hard part comes when you are given a more unfamiliar chemical name like tetrachloromethane, names like limestone and trade names.
What happens when you add MgNO32 to NaOH?
When magnesium nitrate (Mg(NO3)2) is added to sodium hydroxide (NaOH), a double displacement reaction occurs, resulting in the formation of magnesium hydroxide (Mg(OH)2) and sodium nitrate (NaNO3). The balanced chemical equation for this reaction is: Mg(NO3)2 + 2NaOH → Mg(OH)2 + 2NaNO3

What is the formula weight of MgNO32 Express your answer numerically in atomic mass units to the tenths place?
Mg = 24.305 a.m.u. 2 N = 2*14.007 a.m.u. = 28.014 a.m.u. 6 O = 6*15.999 a.m.u. = 95.994 a.m.u. Total: 148.313 a.m.u. (in 6 significant figures) NB. Impossible to reach the 10th place numerically, because more accurate data are unreliable (according to IUPAC-standards)
A solid consists of a mixture of NaNO3 and MgNO32 When 6.50 g of this solid is dissolved in 50.0 g of water the freezing point is lowered by 5.07 what is the composition of each solid?
To find the composition of each solid, use the equation for freezing point depression: ΔT = Kf * m, where ΔT is the freezing point depression, Kf is the cryoscopic constant for water, and m is the molality of the solution. Rearrange the equation to solve for m. Then, use the molality to calculate the moles of solute. From the moles of NaNO3 and Mg(NO3)2, calculate the mass of each in the 6.50 g solid.
How many mol MgNO32 are produced from 2.5 mol KNO3?
First you have to get to a balanced equation 2KNO3+1Mg=1Mg(NO3)2+2K Then you do a mole to mole equation 2.5molKNO3x1mol Mg(NO3)2/(over)2molKNO3=1.25mol Mg(NO3)2 So your answer is 1.25mol Mg(NO3)2 But if you follow the rules of signicicant figures you need to have as many digits in your answer as the given. 2.5mol has 2 significant figures(digits) so your answer needs to have 2 digits Rounding to two digits we get 1.3molMg(NO3)2 Your answer is 1.3molMg(NO3)2
