Reaction that affects the original chemical fomula
Answer:
The correct option is;
Action potentials travel the length of the axon
Explanation:
A dendrite are nerve cell projections that are used for receiving signals from other nerve cells
A neurotransmitter is the chemical, produced by the nerve cell to contain the message the nerve cell intends to transmits across a neural junction, to the cell for which the message is meant such as a muscle cell, gland cell, or other nerve cells
Therefore, the received message from the dendrite by the present neuron are transported using action action potential which is the means by which electrical signals are transported by a neuron through the length of the axon which is the projection of the nerve cell, known as the nerve fiber that conducts action potential which are electrical impulses to other destination by traveling the length of the of the axon to the location of the destination cell of the action potential
Answer: Simple,
Explanation: There is only one atom in a monoatomic ion and there are many atoms in a polyatomic
a. mol O₂=0.5
b. volume O₂ = 25 cm³
c. i. the total volume of the two reactants = 75 cm³
c. ii. the volume of nitrogen dioxide formed = 50 cm³
<h3>Further explanation</h3>
Reaction
2NO(gas) + O₂(gas) ⇒ 2NO₂ (gas)
a.
mol NO = 1
From the equation, mol ratio NO : O₂ = 2 : 1, so mol O₂ :
b.
From Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles
Because mol ratio NO : O₂ = 2 : 1, so volume O₂ :
c.
i. total volume of reactants : 25 cm³+ 50 cm³=75 cm³
ii. the volume of nitrogen dioxide formed :
mol ratio NO : NO₂ = 2 : 2, so volume NO₂ = volume NO = 50 cm³
