a standard copper alloy containing 23.24% Cu was analzed and calculated to contain 23.17%. calculate the relative error of the method in parts per thousand (PPT).​

How many grams of aluminum will there be in 98g of al2o3?

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
