Justine took a sip of milk and immediately spat it out because she realized it had soured. Which path did messages in her nervous system follow to cause this reaction? sensory neurons → sensory receptors → motor neurons → interneurons sensory receptors → sensory neurons → interneurons → motor neurons motor receptors → interneurons → sensory neurons → sensory receptors sensory receptor → interneurons → Sensory neuron → motor neurons

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.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

answer; protein;

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
