Define what kind of redox reaction each reaction below is. Identify the oxidizing as well as reducing agents
A. 2 Ca(s) + O2(g) ---> 2 CaO(s)
B. 2 Al (s) + 6HCl(aq) ---> 3 H2(g) + 2AlCl3(aq)
C. 2 HgO(s) ---> 2 Hg(l) + O2(g)
D. C2H4(g) + 3 O2(g)---> 2 CO2(g) + 2 H2O(l)
E. Si(s) + 2 Cl2(g) --->SiCl4(g)
Sports drinks are beverages designed to replenish water, salts, sugars and other nutrients. A particular sport drink contains 600 ppm sodium by mass. How many mg of sodium would be in a 16.0 oz bottle of this beverage
The sensitivity of a fluorescent sensor can be adjusted by either selecting luminophores with different lifetimes or by modifying the supporting media. Explain why both of these methods are effective.
A mixture of 1.374g of H2 and 70.31g of Br2 is heated in a 2.00 L vessel at 700 K. These substances react as follows: H2(g) + Br2(g) 2HBr(g) At equilibrium the vessel is found to contain 0.566g of H2.
