27.0g of an unknown metal at 100 degrees Celcius was dropped into a beaker containing 313g of water initially at 22.3 degrees Celcius. The final temperature of the mixture was 25.1 degrees. What is the specific heat capacity of the unknown metal?

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
