Becquerel’s experiment consisted of four steps.
1. Get a sample of a uranium salt.
2. Expose the salt to sunlight.
3. Expose photographic plates to the salt.
4. Develop the plates.
A change in which step led to Becquerel’s discovery of radioactivity?

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
