Driving water out of crystals are crystallization process.
The piece of equipment used are evaporating dish.
Explanation:
Crystallization process
- Crystallization is a process of converting crystalline solid state into liquid state.
- It works both in purification and separation step.
- Steps involved in the crystallization process are
a) Nucleation
b) Crystal growth
- It is the oldest unit operation methods.
- Methods involved in this process are solvent evaporation, slow cooling, solvent diffusion and sublimation.
Evaporating dish
- Evaporating dish is a shallow open container.
- Evaporating dish is used to heat and evaporate solids.
- It is made by borosilicate glass or porcelain, which is non-reactive and withstand heat from Bunsen burner.
The answer to your question would be D) chemical bonding because when you are bonding atoms to each other you are creating a new and unique substance
oxygen added to the copper is 3.300 grams.
<span>89.920 - 83.620 = 3.300 g oxygen </span>
<span>which is 0.2063 moles of oxygen. </span>
<span>3.300 g O x (1 mol O / 16.00 g O) = 0.20625 mol </span>
Answer:
63.55 g
Explanation:
The relation between molecular (formula) mass and molar mass Page 4 4 • To obtain one mole of copper atoms (6.02 x 1023 atoms), weigh out 63.55 g copper. The molar mass (M) of a substance is the mass of one mole of entities (atoms, molecules, or formula units) of the substance.
I'm pretty sure the aswer is B.
