What else can I help you with?
Gas is contained in a 125mL flask The actual volume of the flask is 131.5mL What is the volume of the flask in L?
Volume of the flask = 131.5 mL - 125 mL = 6.5 mL = 0.0065 L
What happens when a thermo flask contains some ice cubes?
The ice cubes will help to keep the contents of the thermos flask colder for a longer period of time. The thermos flask's insulation will prevent heat transfer from the surroundings, helping to maintain the temperature of the ice cubes and the contents of the flask. Over time, the ice cubes will melt and help to cool the contents of the flask.
What is flat bottom flask?
A flat bottom flask would be an Ehrlemeyer flask, which is used quite a lot by chemists.anf
Why the temperature in a flask tha contains dry peas doesn't change at the room temperature?
The temperature in the flask remains constant because the peas act as insulation, limiting heat transfer between the inside and outside of the flask. This insulation effect prevents the temperature from changing easily.
A flask fitted with a stopper that is used in the preparation of solution?
volumetric flask
Why is it acceptable to add water to the titration flask?
Once you have measured out your sample and transferred it to your flask, the absolute amount (moles) of sample is fixed. Adding water to the flask will change the concentration in the flask, titrating also adds volume to the flask as well as reacting with the sample. However, the number of molecules of sample you put into the flask will not change by simply diluting it with water.
Why must the weighing scoop be washed when transferring the sample into the conical flask?
Your intention is to transfer only the true sample into the conical flask, not the dirt from the scoop.
What instrument do you use to find liters?
A measuring flask.
Gas is contained in a 125mL flask The actual volume of the flask is 131.5mL What is the volume of the flask in L?
Volume of the flask = 131.5 mL - 125 mL = 6.5 mL = 0.0065 L
If A flask contains 440 mol of liquid bromine Determine the number of bromine molecules in the flask?
There are approximately 2.65 × 10^26 bromine molecules in the flask. This is calculated by multiplying Avogadro's number (6.022 × 10^23 molecules/mol) by the number of moles of bromine present in the flask (440 mol).
What if three identical flasks contain three different gases at stp flask a contains ch4 flask b contains CO2 flask c contains n2 which flask contains the largest number of molecules?
Flask A containing CH4 would have the largest number of molecules because all the gases are at STP (Standard Temperature and Pressure), so they will occupy the same volume. Since CH4 has the lowest molar mass among the gases given, it will have the highest number of molecules in the flask.
Substance that contains the vacuum in a vacuum flask?
Glass
What is another word for triangular flask?
Another word for a triangular flask is a conical flask.
Does a flask have a meniscus?
Yes, a flask can have a meniscus. The meniscus refers to the curvature of the liquid surface in response to the container's shape. A flask with a narrow neck can exhibit a concave or convex meniscus, depending on the liquid it contains.
Can an Erlenmeyer flask measure in grams?
No. An erlenmyer flask measures volume, usually in mililiters, but sometimes in liters. Grams is a measurement of mass, and to measure mass you need a ballance.
What is a small alcohol container called?
UMMM....A bottle? i think it's called a decanter
How does a themos flask work?
Also known as a Buchner or vacuum flask, the flask uses vacuum to filter samples. A vacuum hose is attached to the hose barb and the funnel is placed on top. As the hose creates a vacuum, the sample is filtered through the funnel.
