What does a scientist observe in a chemical's reaction rate? the speed at which the reactants change to products over a given ti
kvasek [131]

Answer:

The speed at which the reactants change to products over a given time.

Explanation:

A chemical's <u>reaction rate</u><u> is the change in the concentration of a reactant or a product with time (in moles per second)</u>.

Remember that during a chemical reaction, reactants are converted to products. Or what is the same, products are formed at the expense of reactants. This can be represented:

reactants → products

Therefore,<u> the progress of a reaction can be followed measuring the decrease in concentration of the reactants or the increase in concentration of the products.</u>

According to the temperature and other parameters, the reaction rate can increase or decrease.

enkephalin-induced depression of single neurons in brain areas with opiate receptors—antagonism by naloxone
kicyunya [14]

Induced depression of single neurons in brain areas with opiate receptors

  • Enkephalin, applied microiontophoretically, depressed spontaneous and glutamate-induced firing of  one neuron in frontal cortex, caudate nucleus, and periaqueductal gray matter, where enkephalin and high concentrations of opiate receptors are met.
  • More than one depressions were blocked by the specific narcotic antagonist naloxone. The results  are durable with a neurotransmitter or neuromodulator role for this new brain pentapeptide.
  • Opium derivatives have been in medical use for the last  2000 years, and may be   longer than any other class of drugs
  • . The brain regions which was  involved in these actions have been identified in some instances by local microinjection of pmole quantities of opioids.

How does elevation affect climate?
Kisachek [45]

As elevation increases, air density decreases resulting in a decreased ability to hold heat.

<h3>Effect of elevation on climate</h3>

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further and the temperature decreases.

P = ρgh

where;

  • P is the air pressure
  • ρ is air density
  • h is elevation
  • g is acceleration due to gravity

As the pressure decreases, air molecules spread out further and the temperature decreases. The decrease in temperature affects the amount of heat that air can hold.

Thus, as elevation increases, air density decreases resulting in a decreased ability to hold heat.
