Answer:

H+  +  OH−  --> H2O

Explanation:

Hydrochloric acid is represented by the chemical formular; HCl. This is an ionic substance so in water it breaks apart into hydrohrn ions; H+ and chloride ions; Cl−. It is a strong acid, hence it completely dissociates.

Potassium Hydroxide is also an ionic substance it also breaks apart in water into potassium ions; K+ and hydroxide ions; OH−. It is a strong base, hence it completely dissociates.

The complete ionic equation for the reaction is given as;

H+  +  Cl−  +  K+  +  OH−  -->  K+  +  Cl−  +  H2O

The Hydrogen ion and the Hydroxide ions combine to form water.

The net ionic equation is given as;

H+  +  OH−  --> H2O

Cl- and K+ ions were cancelled out because they do not undergo any changes therefore are not part of the net ionic equation. They are referred to as spectator ions.

Describe the neutral signaling pathway
galina1969 [7]

Answer:

A neural pathway is the connection formed by axons that project from neurons to make synapses onto neurons in another location, to enable a signal to be sent from one region of the nervous system to another. Neurons are connected by a single axon, or by a bundle of axons known as a nerve tract, or fasciculus.

Which has a higher mass percent of magnesium mgo or mg3n2?
vampirchik [111]
The  compound  that  has   higher  mass percent  is  Mg3N2  which is 72%


explanation
calculate  the %  mass  of Mg  in each  compound

%  composition  of  mg= molar mass of  Mg/  total  molar  mass  of the compound  x100

in MgO  =  24 /40  x100 = 60%

in Mg3N2  =72/100 x100  =  72 %

therefore  the % composition  in Mg3N2  is higher

All of the following statements concerning voltaic cells are true EXCEPT
MissTica

Answer:

oxidation occurs at the cathode.

Explanation:

In a voltaic cell electrons move from anode to cathode. At the anode, species give up electrons. This is an oxidation reaction depicted by the oxidation half equation. At the cathode, species accept electrons and become reduced. This is depicted by the reduction half equation. In summary; in a Voltaic cell, oxidation occurs at the anode while reduction occurs at the cathode.
