What else can I help you with?
What would you see if excess cobalt oxide is warmed with hydrochloric acid?
When excess cobalt oxide is warmed with hydrochloric acid, the cobalt oxide will react with the acid to form cobalt chloride, water, and chlorine gas. The resulting solution may be pink due to the presence of cobalt ions, which are often a characteristic color of cobalt compounds.
What process takes place when zinc chloride solution is warmed?
The water is evaporated and the concentration of the solution become greater.
What happens to a film of bubble solution when the air inside a bottle is warmed and cooled?
When the air inside the bottle is warmed, it expands, creating pressure that can cause the film of bubble solution to expand and create larger bubbles. Conversely, when the air is cooled, it contracts, leading to lower pressure that can cause the bubble film to shrink and create smaller bubbles.
How is a fluid bed used to form granules in the pharmaceutical industry?
Polymeric binder solution is first atomsied. It is then sprayed onto a fluid bed warmed by the air. The air will then cause the solvent to evaporate from the binder solution leading to it being dried.
What is the whole world warmed at?
The whole world is warmed by the sun.
What happens when sodium hydroxide solution is added to calcium carbonate and then warmed?
CaCO3(s)+2NaOH(aq)--->Ca(OH)2(aq)+Na2CO3(aq) When you heat it later, the water in the solution evaporates leaving you with just the salts. Also, it is better to say, calcium carbonate is added to sodium hydroxide solution as you add a solid to a solution not really vice versa.
Which gas is liberated when an alkaline solution of sodium nitrate is warmed with aluminium?
Aluminium react with sodium hydroxide releasing hydrogen.Sodium nitrate is decomposed by heating releasing nitrogen dioxide.
Where is inhaled air moistened and warmed?
Inhaled air is warmed and moistened in the nasopharynx and oropharynx.
When saturated air is warmed?
When saturated air is warmed, its ability to hold water vapor increases, leading to a decrease in relative humidity. This can result in the condensation of excess water vapor, creating clouds or fog if the air is cooled again.
What salt can be prepared by a boiling method?
What method do you mean? At a guess at what the question means: If a salt solution (brine) is warmed until the water evaporates away, white salt crystals are left behind.
Germans warmed their huts by?
Germans warmed their huts by using the body heat of their farm animals.
Why does the temp not change as water is warmed up?
