Answer:
Because the enthalpy change of the reaction depends on the states of matter of the substances, they must be shown for each substance in the equation.
Explanation:
The enthalpy of a substance depends on the particular state of matter in which it occurs.
Therefore, in a thermo chemical equation, all the states of matters for all the chemical species in the equation must be accurately written so that the thermo chemical equation can be meaningful.
The separation can easily be carried out on the basis of the difference in densities of polyehtylene terephthalate (PETE) and high density polyethylene (HDPE). To do this, we may grind the polymers into chips and then begin vibrating the mixture of the plastics. The more dense HDPE chips will settle to the bottom and the less dense PETE chips will remain at the upper portion.
Answer:
sorry to waste ur time but im getting points bc i have a question and i need more points to say ig
M=mol/liter
We know that we have 150ml=.15 L and .1 mol of HCl
Rearranging the molarity equation, we get
mol=M*l
mol=(.15)(.1)
=.015 mol
