3. Calculate and record the moles of benzoic acid in the solvent. Remember to convert your mass of lauric acid to kilograms (1,000 grams per kilogram). moles of benzoic acid = m × kg of lauric acid Mass of Benzoic Acid- .4g Mass of Lauric Acid- 3g PLEASE HELP

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.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:
