Which process represents chemical weathering? Process A: Waves in a River lift rocks which crash down to the river bed and break

Process B: Water in the cracks of rocks freezes and breaks open the rocks

Process C: An organic acid produced by rotting vegetation makes holes in rocks

Process D: Roots of plants push against rocks and make cracks in them

What type of energy do chemical bonds have? what type of energy is it converted to during chemical reactions? question 15 options: chemical bonds have kinetic energy, which is converted to potential energy during chemical reactions. chemical bonds have electric energy, which is converted to potential energy during chemical reactions. chemical bonds have heat energy, which is converted to kinetic energy during chemical reactions. chemical bonds have potential energy, which is converted to heat energy during chemical reactions.

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

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?
