Se sabe que se requiere 38 no de HF .29 N para neutralizar 50 ml de una muestra de KOH. cuál es la normalidad del hidróxido de calcio?​

What is the empirical formula for c4h8o2

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
