Consider the subsequent equations. These may be acid/base or precipitation reactions. If no reaction would take place, simply write no reactions. If a reaction would take place, predict the products, balance the reaction and write net ionic equations.a) V(ClO4)3 (aq) + Rb2S (aq) -->b) HBrO3 (aq) + Fe (HCO3)3 -->c) MgCl2 (aq) + CuSO4 (aq) -->
A 1- L flask is filled with 1.40 g of argon at 25?. A sample of ethane vapor is added to the same flask until the total pressure is 1.05 atm.
Identify (name) each pathway, the enzyme whose activity determines how much glucose-6-P is metabolized by that pathway, one effector (regulatory molecule) which controls the activity of each enzyme, and how the effector affects the activity of the..
