If 1520 J are added to 16.5 g of water at 63.1 c what will the final temperature be

If 90.0 grams of ethane reacted with excess chlorine,how many grams of dicarbon hexachloride would form

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

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
