If two powders are mixed in a flask and the bottom of the flask feels warm what type of reaction is it?
If the bottom of the flask feels warm when two powders are mixed, it indicates an exothermic reaction. This type of reaction releases heat to the surroundings, causing the temperature of the flask to rise. The warmth is a sign that energy is being released as the reactants undergo a chemical change.
Is heating a flask on a hot plate an example of activation energy beginning to react?
No, heating a flask on a hot plate is not an example of activation energy beginning to react. Activation energy refers to the minimum amount of energy required for a chemical reaction to occur, and it is not related to heating a flask. Heating a flask on a hot plate simply refers to the process of applying heat to the flask, which can facilitate a reaction by increasing the temperature and providing the necessary energy for the reaction to proceed.
What would likely happen if you were to touch the flask in which an exothermic reaction were occurring?
The flask might feel cool to the touch as the reactants absorb heat conducted through the flask from your body. (This assumes that the reaction is happening at temperatures below your body temperature.)
What type of chemical reaction is a flaming flask?
This is an example of hydrogen burning.
Why is sodium hydroxide added into the conical flask containing a analgesic or aspirin?
to decrease ph
Why is an excess amount of Na OH added to the conical flask containing aspirin?
to decrease ph

Why Erlenmeyer flask does not have to be dry and why water may be added?
The Erlenmeyer flask does not have to be dry because it is commonly used for mixing solutions or conducting reactions where water or other solvents are needed. Water may be added to the Erlenmeyer flask to dilute a solution, adjust its concentration, or facilitate a reaction. It also helps ensure better mixing and dissolving of substances.
Do you use titrant in conical flask?
yes we use titrant in the conical flask ,this is because titrant is a solution we use in burrete for titration in this process we titrant the solution in the conical flask along with an indicator
A flask is weighed and has a mass of 50.0 grams Then 2.0 grams of sodium metal is added to the flask Chlorine gas is pumped into the flask This allows the sodium metal to react completely with c?
The sodium metal will react with chlorine gas to form sodium chloride. The reaction involves a single displacement reaction where sodium replaces chlorine in its diatomic form to form NaCl. The final mass of the flask will increase by 2.0 grams due to the formation of sodium chloride.
Why do you add sodium hydroxide into the conical flask containing the analgesic tablet?
Sodium hydroxide is added to the conical flask to create a basic environment, which helps to break down the tablet and facilitate the reaction necessary for the analysis of the active ingredient. This reaction is important for quantifying the amount of the active ingredient present in the tablet.

Heating a flask on a hot plate simply refers to the process of applying heat to the flask, which can facilitate a reaction by increasing the temperature and providing the necessary energy for the reaction to proceed.
Which solution in the titration is taken in conical flask?
The solution being titrated is placed in the conical flask. The titrant (the solution being added during titration) is then slowly added to the solution in the conical flask until the endpoint is reached.
Why is excess amount of sodium hydroxide added to the conical flask?
Excess sodium hydroxide is added to ensure that all the acid in the solution is fully neutralized. This helps to guarantee that the reaction goes to completion and that the pH of the solution is sufficiently raised.
What would likely happen if you were to touch the flask in which an exothermic reaction were occurring?
The flask might feel cool to the touch as the reactants absorb heat conducted through the flask from your body. (This assumes that the reaction is happening at temperatures below your body temperature.)
