The decrease in volume of air is due to the copper powder absorbing oxygen from the air during the process, forming copper oxide. This chemical reaction reduces the amount of gas present in the container when it is cooled back to room temperature.
This depends on the nature of this solid, temperature, pressure, stirring, particles dimension etc.
Not all the solids will dissolve in water. Different solids have different solubilities (some will dissolve more than others). The higher temperature, the more will dissolve
The solubility of iodine in water is around 0.3 g per 100 mL of water at room temperature, making it the maximum amount that can dissolve under those conditions.
i performed this experiment and it comes out around 60 (radians*100cm3/gm*dm) where length of polarimeter tube was 2 dm and concentration was varied from 40 gm/100cm3 to 20gm/100cm3
The volume of the water in Beaker X will be 100cm3, as you are not adding any more water to the equation (50X+100Y is not 150Y or X, but 50X+100Y) The total volume of matter in Beaker X will be 150cm3, and if the beaker is labelled, the volume measure will indicate 150cm3 due to the displacement of water. But as the answer to your question, the volume of water in Beaker X must be 100cm3 even though visual indicators will not show this due to the displacement of water by marbles
No, 100cm3 is only 0.026 gallon.
This depends on the nature of this solid, temperature, pressure, stirring, particles dimension etc.
1 gallon has more volume. 100cm3 is basically 1/10th of a liter which is 1,000cm3
What is the volume of 35.7g of sodium chloride in 100cm3 of cold water?
No.
you divide by 1000 to convert from cm3 to dm3, so 100cm3 is 0.1dm3
Approximately 30.4 grams of potassium chloride would dissolve in 100 cm3 of water at room temperature.
Its 100cm3 , or 100ml, or 10-4 m3
1 ml = 1cm3So, 100ml = 100cm3
