The liquid to solid process using the particle theory is as below
- The process that involve change of liquid to solid is known as Freezing
- It involve change from a high energy state to lower energy
- The constant temperature at which a liquid change to solid by giving out heat energy is called freezing point of the liquid
- when liquid are cooled the thermal energy of particles decrease.
- The cohesive forces between the particles strengthen to such extent that particles can have relative motion with each other and they occupy the fixed position, thus liquid is converted to solid
The percentage of hydrogen in C7H18 is calculated as follows:
[18/(12*7+1*8)]*100=18%
The amount of hydrogen in 5.2moles is given by:(18/100)*5.2=0.94moles
Answer:
Tree sap flows over the leaf and preserves it.
Explanation:
Amber would preserve the image.
Answer:
Explanation:
Hello,
In this case, for the given reactants we identify the following chemical reaction:
Thus, we evidence a 1:1 molar ratio between KOH and HCl, therefore, for the complete neutralization we have equal number of moles, that in terms of molarities and volumes become:
Hence, we compute the volume of HCl as shown below:
Best regards.
