The concentrations of a reaction are measured to determine reaction rates. if the concentration of the reaction's product increases from 0.0250m to 0.484m in 3.00mins, determine the average reaction rate during this time period?
1.28 × 10-3 mol/(l × s)
2.55 × 10-3 mol/(l × s)
5.10 × 10-3 mol/(l × s)
1.02 × 10-2 mol/(l × s)

2. given that most biochemical (other than coal) rocks react with hydrochloric acid, what does that tell you about organisms?

Explain how scientists use geologic time to determine the age of landforms.

True or false: (a) the strings of little red dots represent carbohydrates. (b) the model is called a bilayer because there are two main types of molecules present, lipids and proteins. (c) the many black lines represent amino acid tails. (d) this model shows membrane transport. (e) the blue ovals are hydrophobic. (f) the blue ovals represent phospholipid heads.
