If 3.45 grams of mg are burned how many grams of mgo are produced

Mass of MgO produced = 5.72 g

Explanation:

Mass of Mg = 3.45 g

Molar mass of Mg = 24.305 g/mol

No. of mol of Mg =

No. of mol of Mg =

From the reaction coefficient,

2 mol of Mg form 2 mol of MgO

So, 0.142 mol of Mg form 0.142 mol of MgO

Molar mass of MgO = 40.3044 g/mol

Mass of MgO in g = No. of mol × Molar mass

                              = 0.142 mol × 40.3044 g/mol

                              = 5.72 g

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

yes the answer is total mass in unchanged   : )
