Answer:
5.15 moles
Explanation:
2zn + o2 = 2zno
5.15 2.57 5.15 moles
nzno=500/(16x2+65)= 5.15 moles
-> nzn = 5.15 x 2 ÷ 2 = 5.15 moles
Answer:
fractional distillation since ot depends on the different liquids to have different boiling points
Answer: The answer is C
Explanation:the salt fits the definition of a mineral because it's a naturally occurring compound that has a definite composition and a crystalline structure. It has a crystalline structure because of its repeating pattern
Answer:
A fluid is a medium that has a defined mass and volume, but no fixed shape, at a constant temperature and pressure. This may include gases, liquids, plasmas, and to some extent plastic solids. A fluid can flow and deform, preventing it from carrying loads in a static equilibrium. A fluid is always compressible and internal frictional forces always occur due to the viscosity of the fluid.
