WHY EMPTY CRUCIBLE HEATED BEFORE STARTED EXPERIMENT?
The empty crucible is heated AND WEIGHED, so that you can drive off any moisture and/or other particles that might add to the weight of the empty crucible. You will eventually weigh the crucible again at the end of the experiment to determine the weight (mass) of some compound. Thus, it is important to have a correct "starting mass" of the crucible.
Why is the magnesium strip polished before weighing?
The magnesium strip is polished before weighing to remove any surface impurities, such as dirt or oxidation, that could affect the accuracy of the measurement. By ensuring the strip is clean and free of contaminants, the weight obtained will be more accurate and reliable.
How much glycine is present in magnesium glycinate?
Magnesium glycinate contains approximately 14.1 glycine by weight.
What is the purpose of taring the crucible before using it in an incineration process?
It reduces errors caused by variations in the weight of the crucible itself.Taring is accurately establishing the empty weight of the crucible, which can vary with contaminants, residue, or oxides. By repeatedly heating, cooling, and weighing the crucible, until there is only an acceptable variation between weighings, the actual weight of samples before and after incineration can be more precisely measured.
What was the twelfth element on the periodic table?
The twelfth element on the periodic table is magnesium. It is a metal known for its light weight and is commonly used in alloys and as a component in fireworks.
What are crucible thongs used for?
1. Thong or clipmust be use when to weight or transfer the crucible because to avoid it absorb excess moisture from hand and this situation will affect the result.
Why must be crucible be cold before weighing?
A crucible must be cold before weighing to ensure accurate measurements. If a hot crucible is weighed, it can cause air currents and thermal convection that affect the scale's reading, leading to an inaccurate measurement of the crucible's weight. Additionally, weighing a hot crucible can risk damaging the balance or scale. Lastly, cooling the crucible allows for any residual materials to settle, providing a more precise weight.
Do magnesium help get rid of your weight?
Any link exist between magnesium and your weight.

If an antacid weighs 2.50g and contains 400mg magnesium hydroxide what is the percentage of the tablet that is magnesium hydroxide?
The weight of the tablet is 2.50g, which is the total weight. The weight of magnesium hydroxide is 400mg. To find the percentage, convert the weight of magnesium hydroxide to grams (0.400g) and divide by the total weight, then multiply by 100. The percentage of the tablet that is magnesium hydroxide is 16%.
What are Giles Corey last words in the crucible?
"more weight"
