Formula of magnesium nitride is written as `Mg_XN_Y`, then value of (X+Y) is

Give the formula of Magnesium nitride

Give the formulae of Magnesium nitride

1 g of magnesium was burnt in air and the ash produced in extracted with excess of water when 8.96cm^(3) of ammonia is produced at S.T.P. calculate the amount of Mg, which was converted into magnesium nitride. Also calculate the amount of MgO present in the ash.

Correct the statements : The formula of magnesium nitride is MgNO_(2) .

Silica reacts with magnesium to form magnesium compound (X).(X) reacts with dilute HCl and forms (Y) . (Y) is:

If 2x-3y=7 and y=3 , then what is the value of x?

If sigma _x =10 , sigma _y =10 , then the value of Cov(x,y) is

If e^(x)=y+sqrt(1+y^(2) then the value of y is

When x=4 and y=2 find the value of : x+y

If f(x) = x/(x-1)=1/y then the value of f(y) is
