Answer:
any reaction where substance combined with oxygen
Only test 2 will indicate a chemical property of sodium bicarbonate. The other tests are done to confirm its physical properties. Vinegar, or acetic acid, CH3COOH, reacts with NaHCO3 to form sodium acetate, carbon dioxide and water. The reaction fizzes due to the release of CO2. Test 1 shows the solubility of NaHCO3 in water, while test 3 tests for its melting point. Both are physical properties.

Answer:
185.1 m/s
Explanation:
The average speed of an object is a scalar quantity telling us how fast is the object moving over a certain distance.
This quantity is calculated as
where
d is the distance covered by the object
t is the time elapsed
v is the average speed
In this problem we have:
d = 1500.0 m is the distance covered by Ken
t = 8.1018 s is the time taken
Substituting into the formula, we find the average speed:
