Two things, primarily: 1. The 3-iron has a longer shaft (the skinny metal part between your hands and the clubhead) 2. The 3-iron has less loft, meaning that the ball doesn't fly as high as with a 9-iron. I don't recall exactly but I think a 3-iron has about 21 degrees of loft compared to maybe 48 degrees for a 9-iron. These two things make the 3-iron hit the ball much farther than a 9-iron, maybe 200-225 yards vs. 100-125 yards for the 9-iron. But it is also a much harder club to make good contact with, due to the longer shaft and lack of loft.

to replace a 3 iron or 4 iron
Golf is played in a golf course. A typical golf course has 18 holes, however, smaller golf courses have 9 holes as well. Championship level golf courses are known to have even 27 or 36 separate holes.
Ferrous ion carries a +2 charge and Ferric carries + 3
Iron II nitrate contains an iron ion with a 2+ charge and has the formula Fe(NO3)2. Iron III nitrate contains an iron ion with a 3+ charge and has the formula Fe(NO3)3
A 9 iron is shorter, and has a little more added loft to it, so you can hit the green and not go over. A 7 iron is a mid iron, and is a little longer, and the loft is less than a 9 iron so you can have a little more added distance than a 9.
no there isn't anything good about an iron golf club and: 1.it is dangerous and anyone behind you can get hurt while your swinging 2.it is too heavy 3.its no better than any normal golf club
Each golf club will have a number and/or a name. A few examples 1 wood. 3 iron. sand wedge. putter.
A 3 iron is usually 21 degrees and and 4 iron 24 degrees, so a strong 4 iron. Depends on manufacturer really. And also remember the shafts on hybrids are slightly longer, perhaps by an inch which means the ball goes further.
The difference between 7 and 3 is 4.
the difference between a number and 3 is
It's basically a difference in the electron shell arrangement of the central Iron atom. In Iron II Nitrate, Iron has a +2 charge (Fe2+) and in Iron III Nitrate, Iron has a +3 charge (Fe3+). So there are two nitrates attached to Iron II: Fe(NO3)2 and three nitrates attached to Iron III: Fe(NO3)3.They would both behave nearly identical in solutions since nitrates dissociate 100% but the Fe2+ and Fe3+ ions are useful in voltaic cells.
