Want this question answered?
The crucible must be cold before weighing because the heat from the crucible will warms the surrounding air
why Covering the crucible with its lid as soon as the magnesium starts burning
The crucible must be weighted at a constant temperature, generally 20 oC. During an analytical determination - for example - all the weighings must be made at the same temperature. Also a hot crucible has a negative influence on the balance.
We want to weight exactly only the material - variations of the crucible mass lead to errors. That's why the mass of the crucible must be stabilized.This is very important in gravimetry, it is a basic rule.
Yes. When it is a literary work that can stand alone, it must be underlined.

If not the substances or chemical in the crucible will flow out and drip onto the table

i dont no either

Not twice in a row, after you beat it the first time you must finish the next part of the story line and then you can go back to the crucible and fight again.
it must be cooled in the desiccator in order to take the correct measurement on the scale while performing the experiment.
the Pokemon that used mean look must still be in battle for the move mean look to work if you switch the Pokemon that used mean look out , the mean look's effect will wear off hope i could help! T.A.S.N.
