The graph of the heating of methanol has been attached.

The temperature at 170 K is approximately the melting point of methanol.

The temperature at 350 K is approximately the boiling point of methanol.

If we provide heat before 170 K temperature then all the heat provided to the methanol will result in rise in temperature of methanol in solid form.

If we provide heat at 170 K temperature then all the heat provided to the methanol will result in change in physical from of methanol from solid to liquid.

If we provide heat after 170 K temperature and before 350 K temperature then all the heat provided to the methanol will result in rise in temperature of methanol in liquid form.

If we provide heat at 340 K temperature then all the heat provided to the methanol will result in change in physical from of methanol from liquid to gas.

If we provide heat after 350 K temperature then all the heat provided to the methanol will result in rise in temperature of methanol in gas form.

So, the heat given to methanol will rise its temperature except at its Boiling and melting point. At those temperature heat will change the physical form of methanol first. and the graph also have been attached of between boiling point and melting point as given in question  .

Please help!! 20 points!! Posted this previously and forgot to change it to 20 points but it is now
spayn [35]

Answer:

0.571 mol

Explanation:

Given data:

Number of moles of NaHCO₃ = 0.571 mol

Number of moles of CO₂ produced = ?

Solution:

Chemical equation:

NaHCO₃ + C₃H₆O₃   →     CO₂  + C₃H₅NaO₃ + H₂O

Now we will compare the moles of CO₂ with NaHCO₃ from balance chemical equation.

                             NaHCO₃          :            CO₂

                                    1                :               1

                                 0.571            :            0.571

So number of moles of CO₂  produced are 0.571.

If the half-life of a radionulide is 1 month, what percent remains after 4 months?
Aliun [14]

Answer:

6.25% of the original amount

Explanation:

half-life means that half is gone for every certain period of time. Because the half life is 1 month, only half of the 'radionulide' is left every month.

after 1 month= 50%

after 2 months= 25%

after 3 months= 12.5%

after 4 months= 6.25%

What is always true of a strong acid?
sveta [45]

Strong acids provide more H+ in the aqueous solution than the weak acids. This excess amount of H+ conducts more electricity in the solution.

Explanation:

The strong acid provides more H+ ion whereas the weak acids produce less H+ in the aqueous solution resulting in less amount of electricity conduction in the solution.

Weak acid- lesser amount of H+ produced

Strong acid- greater amount of H+ ( proton) produced.
