Answer:
Analytical Groups I and II
Explanation:
Precipitation reactions happen when anions and cations in aqueous solution mix together to form an insoluble ionic solid which is now referred to as a precipitate.
Whether or not a type of reaction like that takes place can be determined by utilizing the solubility principles for common ionic solids.
It deteriorates. Definitely more than when you started.

Explanation:
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.

The new volume if the balloon is cooled at constant pressure is 3.98 L.
Charles's law, states that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature if the pressure remains constant.
The new volume is calculated using the Charles law formula
V₁ / T₁ = V₂ / T₂
where,
V₁ = The initial volume of air = 4.24 l
T₁ = 23.00 °C into kelvin = 23 +273 =296 K
T₂ = 5.00 °C into kelvin = 5.00 + 273 = 278 K
V₂ = ?
By making V₂ subject the subject of the formula by multiplying both sides by T₂
V₂ = ( V₁ × T₂ ) / T₁
V₂ = (4.24 L × 278 K) / 296 k
= 3.98 L
Therefore, the new volume, if the balloon is cooled at constant pressure, is 3.98 L.
An air-filled balloon will contract when chilled and expand when heated. This occurs because the gas that makes up the air within the balloon expands when it is warm and contracts when it is cool.
