Colligative
properties calculations are used for this type of problem. Calculations are as
follows:<span>
</span>Look up the freezing point of benzene, then delta T = f.p.=3.5 = Kf*m
<span>Solve for molality. </span>
<span>molality = moles/kg solvent </span>
<span>Solve for moles. </span>
<span>moles acetic acid = grams acetic acid/molar mass acetic acid </span>
<span>Solve for molar mass. You would expect to find 60 for the molar mass CH3COOH.</span>

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
3. Select the coefficient of the substance with the most complex chemical formula equal to 1
Reaction
TiCl₄+H₂O⇔TiO₂+HCl
give coefficient
TiCl₄+aH₂O⇔bTiO₂+cHCl
Ti, left=1, right=b⇒b=1
Cl, left=4, right=c⇒c=4
H, left=2a, right=c⇒2a=c⇒2a=4⇒a=2
O, left=a, right=2b⇒a=2b⇒2=2.1⇒match
Balanced equation :
TiCl₄+2H₂O⇔TiO₂+4HCl
If the earth was to exceed its weight the of people the population would then decrease because the environment couldnt sustain that many people the carbon would overwhelm oxygen......but its simply just a matter of natural resources (like food) more than anything else.
Answer:
This is a reversible change. Similarly, if you boil water, it evaporates and becomes water vapor. When you cool this vapor down, it turns back to water. A change which cannot happen backward, that is, it cannot be reversed is called an irreversible change.
