process by which one separates compounds from one another by passing a mixture through column that retains some compounds longer than others.
Answer:
Sulfur (Acidic)
Explanation:
Lime would just add to the amount of alkalinity, and water would do nothing much due to it being neutral.
Sulfur, which is acidic, will neutralize the pH level. The opposite of Alkalinity is Acidity, and Neutrality is in the middle of the two.
Answer:
Single replacement
Explanation:
Chemical equation:
2Al(NO₃)₃ + 3Ca → 3Ca(NO₃)₂ + 2Al
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
All other options are incorrect because,
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AD +CB
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
Decomposition reaction:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Combustion reaction:
Reaction in substance react with oxygen and form carbon dioxide and water.
Answer:
The SI unit for specific enthalpy is joule per kilogram. It can be expressed in other specific quantities by h = u + pv, where u is the specific internal energy, p is the pressure, and v is specific volume, which is equal to 1ρ, where ρ is the density.
