Which is most likely a chemical property? Oxidation state: the charge an atom has if it was bonded ionically to other atoms. Different oxidation states indicate different abilities to bond with other atoms. Melting point: the temperature at which a solid turns into a liquid. Different substances have different melting points. Density: the amount of a substance that fits in a certain volume. Different states of matter of the same substance can have different densities. Conductivity: the ability to transfer electrical charges. Conductivity is different in different substances.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

where are the choice options?

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
