Why do oils leave a translucent spot on paper even after drying, while ethanol and water do not.Question 19 What will happen to the rate of a first order reaction if the reactant concentration is doubled? O The rate of reaction will double. O The rate of reaction will not change. O The rate of reaction will quadruple. The rate of reaction will be zero.rank them by freezing and boiling points on a scale of 1-4. 1 being the lowest boiling point, 2 next to the liquid with the next higher boiling point, and so on.
