Enter the net ionic equation for this reaction. Express your answer as a net ionic equation. Identify all of the phases in your
Lisa [10]

Answer:

2H+(aq) + 2OH-(aq) → 2H2O(l)

Explanation:

Step 1: The balanced equation

2HCl(aq)+Ca(OH)2(aq) → 2H2O(l)+CaCl2(aq)

This equation is balanced, we do not have the change any coefficients.

Step 2: The netionic equation

The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will.

2H+(aq) + 2Cl-(aq) + Ca^2+(aq) + 2OH-(aq) → 2H2O(l) + Ca^2+(aq) + 2Cl-(aq)

After canceling those spectator ions in both side, look like this:

2H+(aq) + 2OH-(aq) → 2H2O(l)

Why might a geologist ask an analytical chemist to help identify the minerals in a rock.
Stels [109]

A geologist would ask the analytical chemist to identify the rock's composition. Chemists gather data from afar and analyze matter back to earth.

<h3>Who is a geologist ?</h3>

A geologist is a scientist who focuses on the processes that shape terrestrial planets and the solid, liquid, and gaseous stuff that makes up Earth. Although training in physics, chemistry, biology, and other sciences are sometimes helpful, geologists typically pursue geology as their field of study. Geology includes a significant amount of field study (field work), even if many of its subdisciplines also involve laboratory and computer work.

Geologists look for natural resources like oil, gas, precious and base metals in the energy and mining industries. They are also in the vanguard of efforts to prevent and lessen the effects of natural disasters and hazards like earthquakes, volcanoes, tsunamis, and landslides.
