What else can I help you with?
Is heat produced or absorbed when alkali metals react with water?
Produced, in great abundance!
Dilute in a sentence?
I will dilute the gravy by adding the milk and heat.
Does adding chemicals to water increase temperature?
No, adding chemicals to water typically does not increase the temperature of the water. The temperature of the water is determined by its initial temperature and any external heat sources or processes. Chemical reactions involving the added chemicals may release or absorb heat, but this would not necessarily increase the overall temperature of the water.
What gas was produced when water is being added to Magnesium Oxide?
When water is added to magnesium oxide, magnesium hydroxide is produced. This reaction also releases heat.
Which substances when added to water will cause the greatest increase and decrease in water temperature?
Adding hot water will cause the greatest increase in water temperature, as it has a higher initial temperature. Adding ice will cause the greatest decrease in water temperature, as it absorbs heat from the water to melt and reach thermal equilibrium.
What is the effect of adding more water to the following equilibrium reaction?
Equilibrium is pushed to the reactant side
What is it called when water vapor is produced by heat?
steam
Why heat is evolved while adding water to sodium hydroxide?
This is called hydration energy (heat).
Is heat produced or absorbed when alkali metals react with water?
Produced, in great abundance!
Can you heat mineral water?
Yes you can. Tap water has minerals in it too. You can heat any substance: heat is the amount of energy, so your just adding energy.
What is the reaction of sulphuric acid in water?
It is an exo thermal reaction. It means, heat is produced when they get mixed together.So, we have to be very, very careful while adding water with sulphuric acid, in case to get it diluted, because enormous heat will be produced.You should not pour water on sulphuric acid kept in a bowl. It is very dangerous. Why?Just think. When you pour water on sulphuric acid, enormous heat will be produced which make water to expand abruptly and so an explosion becomes possible which in turn spills the acid all around and even on the person who has poured water on it.So the intelligent way is, instead adding water to the acid it will be better adding acid to water. That too, using a glass rod. Sulphuric acid is poured in smaller amount at top edge of the glass rod kept inclined in a bowl containing water. The acid slowly descends into the water and as soon as it descends heat will be produced. So using another glass rod we have to stir well the water in the bowl so that the heat produced will be distributed all over.This is the right technique to prepare dilute sulphuric acid.The balanced equation is:H2SO4 + 2H2O -> 2H3O+ + SO42-
What is hydrotermal energy?
Hydrothermal - heat produced by hot water, especially water heated underground by the Earth's internal heat
What gas is produced when hydrochloric acid is added to muriatic acid?
Nothing happens. The two are different names for the same chemical. If the two are different concentrations, though, the effect will be like adding water to the more concentrated one. Like when adding water and acid, heat and splashing may occur! Do this safely with proper protective gear, and with the container able to accept any heat generated due to the water + acid.
Does Boiling Water increase heat energy?
Boiling water involves converting liquid water to steam by adding heat energy. The heat energy increases the temperature of the water until it reaches its boiling point, at which point the water vaporizes into steam.
What is produced when a compound is heated?
Your question is invalid, your question should be What is separated when a compound is heated, because heating a substance is basically adding energy to it. and the energy is likely to separate compounds. For example when you add electricity(energy) to water it will separate water into oxygen and hydrogen. It will also apply for heat energy, If you add enough heat to separate the bond of water.
How is steam produced to run engine?
By using a heat source to boil water.
Acetylene gas C2H2 is produced by adding water to calcium carbide CaC2?
Yes, acetylene gas (C2H2) is produced by the reaction of calcium carbide (CaC2) with water. The chemical reaction generates acetylene gas, calcium hydroxide, and some heat. This process is commonly used in industrial settings for welding and cutting applications.
