To dispense half a drop, you open the stopcork very carefuly and let the droplet appear and start to grow. Once the droplet reaches half it's usual size, close the stopcork. The droplet should now be hanging from the burette. Wash it down into the solution with your solvent wash bottle.

Determine the amount of time it takes for three fourths of a radioactive sample of an isotope to decay?
The half-life is 4 days. That means half of it will be gone in 4 days, and that leaves half of the original sample. In another 4 days, half of the remaining half will have decayed. And that will leave only 1/4 th of the original sample. That means 3/4 ths of the original sample will have decayed. In 8 days, three fourths of a sample of a radioactive element with a half-life of 4 days will have decayed.

What is the difference between drop forging and press forging?
Drop forging is when half of the die is dropped from a height onto the other half of the die, which will contain the hot metal workpiece to be formed. Drop forging is used for mass production. Press forming is instead of dropping half the die onto the other half the two halves are put together and pushed together under a large pressure (up to about 10000 tons) forming the object the difference is that drop forming leaves the centre of the metal not so hard as the outside, but press forming gives more uniform hardness for larger components
