The density of magnesium is 1.7 g/cm3, and the density of iron is 7.9 g/cm3. Consider a block of iron with a mass of 819 g. What is the mass of a block of magnesium that has the same volume as the block of iron?
What do salads turn into chemically formula andhow does it get into your bloodstream. What are some healthy foods for cognitive health? Like for concentration and studying. Give me like a list of 15 foods.
To learn how to calculate the solubility from Ksp and vice versa. Consider the following equilibrium between a solid salt and its dissolved form (ions) in a saturated solution:
What conclusions can you draw about the mobility of metals in acidic environments?
The initial DO of the mix is 9.0 mg/L. After 5 days, the DO is 4.0 mg/L. After a long period of time, the DO is 2.0 mg/L, and it no longer seems to be dropping. Assume nitrification has been inhibited so the only BOD being measured is carbonaceous..
