The smallest division on this ruler is 0.1 cm. Therefore when making this measurement you
must estimate to 1 place of uncertainty which is 0.01cm. The length of the pencil would be
recorded as 9.50cm.
The author read this as 9.50 cm. I think it looks a little over - like 9.51 cm. The last
digit is an estimate, so we don't need to agree. If you think it is right on the dash,
you need to use a zero for your estimated digit as the author did.

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
