Answer:

Hello there, the question asked is not complete (that is the reaction is not given) and similar Question could not be found. Hence, we will go with the information given above and make little assumptions.

Explanation:

So, from the the question above there is the need to determine the theoretical yield from the given starting materials that is 10 ml of the alcohol and 10 ml of 12 molar HCl g. So, let's say the alcohol given can be any alcohol Compound.

Thus, the equation showing the reaction is given as;

HCl + ROH =====> RCl + H20.

That's one mole of HCl react with alcohol to produce CH3Cl and water.

Let's assume that the HCl is the limiting reagent.

We have 10ml of 12M , thus the total number of moles = concentration × volume = 10mL × 12 = 0.01L × 12 = 0.12moles.

If 1 moles of RCl = 1 mole of HCl.

Then, y g/mol of RCl = 1 mol of RCl.

Thus, we have y (gram/mol) of RCl.

Therefore, the theoretical yield = .12 moles × y g/mol. = 0.12y grams.

SUMMARY: The theoretical yield is calculated by Determination of the mass in gram of the product through the use of limiting reagent.

A) How much energy would be required to melt 500 grams of ice at 0°C to water at 0°C?
baherus [9]

Heat required = Q = 40 kcal

<h3>Further explanation</h3>

Given

mass of 500 g ice

Required

Heat required

Solution

The heat to change the phase can be formulated :  

  • Q = m.Lf (melting/freezing)  
  • Q = m.Lv (vaporization/condensation)  

Lf=latent heat of fusion  

Lv=latent heat of vaporization  

Lf for water = 334 kj/kg=6.01 kJ/mol = 80 cal/g

Phase change(ice to water)

Q=  500 g x 80 cal/g

Q = 40 kcal

Certain compound contains 7.3% carbon, 4.5% hydrogen, 36.4% oxygen, and 31.8% nitrogen. It’s reality molecular mass is 176.0. Fi
erastovalidia [21]

Answer:

The answer to your question is:

Explanation:

Data

carbon        7.3%          =     7.3g

hydrogen    4.5%         =      4.5g

oxygen       36.4%         =     36.4 g

nitrogen     31.8%         =     31.8 g

Now

For carbon

                    12 g --------------------1 mol

                    7.3 g     -------------     x

                       x = 7.3/12 = 0.608 mol

For hydrogen

                 1 g   --------------------  1 mol

                 4.5 g  ------------------    x

                   x = 4.5 mol

For oxygen

             16 g ------------------- 1 mol

             36.4 g ----------------    x

             x = 2.28 mol

For nitrogen

              14 g   ----------------   1 mol

              31.8 g ---------------    x

             x = 2.27 mol

Now divide by the lowest result, the is 0.608 from carbon

carbon              0.608/0.608 = 1

hydrogen           4.5/ 0.608 = 7.4

oxygen              2.28/0.608 = 3.75

nitrogen             2.27/0.608 = 3.73

Empirical formula = CH₇O₄N₄
