When choosing a suitable indicator for a titration between a strong acid and a weak base, the indicator should change color in the pH range of:

exactly 7

less than 7 (slightly acidic)

greater than 7 (slightly basic)

near 14 (very basic)

What happens to a liquid when it releases enough energy

Some solutes have large heats of solution, and care should be taken in preparing solutions of these substances. The heat evolved when sodium hydroxide dissolves is 44.5 kJ/mol. What is the final temperature of the water, originally at 20.

Nitric oxide (no) reacts with oxygen gas to form nitrogen dioxide (no2), a dark brown gas: 2no (g) + o2 (g) → 2no2 (g) in one experiment, 0.863 mol of no is mixed with 0.501 mol of o2. determine which of the two reactants is the limiting reactant.
