H2 + I2 > 2Hl
1.2 mol of hydrogen gas reacts with 1.0 mol of iodine vapour, after 5 minutes 0.6 mol of iodine remained.
A) calculate the number of moles of hydrogen that have not reacted after 5 minutes.
B) calculate the number of moles of hydrogen iodide that have been made after 5 minutes.
please help me

............H2 + I2 ==> 2HI
I...........1.2..1.0......0
C...........x.....x.....2x
E................0.6........
I2 reacted must be 1.0x = 0.6 and solve for x.
Then E for H2 must be 1.2x = ?
Then HI must be 2x.
