PV=nRT
n=2.4 moles
T=273.15+50=323.15K
P=2*101325=202650 Pa
R=8.31
Solve for V:
V=nRT/P=2.4*8.31*323.15/202650=.032m^3
Set a piece of pH paper in front of each solution before testing to keep organized.
Use a transfer pipet to remove a few drops from the solution to drop onto the paper.

Answer: -
D. Network
Explanation: -
Diamond is an allotrope of carbon. In diamond each carbon atom makes four bonds to other carbon atoms.
They exist in tetrahedral shape.
Diamond has strong covalent bonds. They extend in all the three dimensions
Such covalent bonds are called network covalent bonds. They require significant amounts of energy to break.
The correct option is C.
When glucose is stirred into water to form a solution, then glucose is the SOLUTE and water is the SOLVENT. A solute refers to a substance that is dissolved in a solvent. For instance, salt is the solute that is dissolved in salt solution. A solvent on the other hand refers to the liquid into which the solute was dissolved. For instance, in the case of salt solution, water is the solvent, because it is used to dissolve the salt.
