Children have about 1016 synapses that can transfer signals between neurons in the brain and between neurons and muscle cells. suppose that these synapses simultaneously transmit a signal, sending 1000 calcium ions (ca2+) across the membrane at each synaptic ending. determine the total electric charge transfer in coulombs during that short time interval. by comparison, a lightning flash involves about 5c of charge transfer. (note: this is a fictional scenario. all human neurons do not simultaneously produce signals.) e=1.6×10−19c.

3.2 C

Explanation:

e = Charge of electron =

Number of synapses =

Signals transferred by each synapse 1000 calcium ions

Each calcium ion carries 2 charges

Number of charges would be

Total charges would be

Charge is given by

The total electric charge transfer in coulombs during that short time interval is 3.2 C

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
