A sample of liquid water loses 7840 J of heat energy and its temperature
changes a total of 38°C. What is the mass(m) of the sample of water in g?
(s of water = 4.184 J/gºC) Round to then nearest whole number and do not
include units. *

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
