Li made note cards to help him study for a test. The cards describe the steps required to calculate percent yield. However, Li d

ropped his note cards, so they are now out of order. Place the steps in the correct order by entering the numbers 1 through 5 next to the correct steps below.
Calculate the theoretical yield of the reaction.
Write a balanced chemical equation.
Check that all significant figures are correct in the calculated value.
Determine the limiting reactant in the reaction.
Divide the actual yield by the theoretical yield and multiply by 100.

Answer:   3 Calculate the theoretical yield of the reaction.

 1 Write a balanced chemical equation.

5 Check that all significant figures are correct in the calculated value.

2 Determine the limiting reactant in the reaction.

4 Divide the actual yield by the theoretical yield and multiply by 100.

Explanation:

Let´s Check out how to develope the steps

1 Write a balanced chemical equation: This can be made by checking that both sides of the equation have  the same number of the atoms .

2 Determine the limiting reactant in the reaction: Let´s calculate how much product you can obtein with one of the reactans and then you calculate how much product you obtein with the other reactant. The reactant that produces a lower number is the limiting reagent.

3 Calculate the theoretical yield of the reaction.  When having the amount of product obtenied from the limiting reagent, that is actually the "theoretical yield" assuming the reaction is completed at 100%

4 Divide the actual yield by the theoretical yield and multiply by 100: When dividing  the actual yield by the theoretical yield and multiply by 100, that is actually the percentage yield.

5 Check that all significant figures are correct in the calculated value.

What is the specific heat of ethanol if 4650 j are required to raise the temperature of 250.0g of ethanol from 22.0oc to 29.6 de
Alchen [17]

Answer:

C=2.45\frac{J}{g\°C}

Explanation:

Hello there!

In this case, since the thermodynamic definition of heat in terms of mass, specific heat and temperatures is given by:

Q=mC(T_2-T_1)

We are to calculate the specific heat of the ethanol as shown below:

C=\frac{Q}{m(T_2-T_1)}

Thus, by plugging it the given data we can obtain:

C=\frac{4650J}{250.0g(29.6-22.00\°C)} \\\\C=2.45\frac{J}{g\°C}

Regards!

Predict products or C3H8 + O2 via combustion
EastWind [94]
When propane   is  burned  in  air  in  a process  known  as  combustion  it  produce   carbon  (IV) oxide  and  water
 the  word  equation  is  as follows,
  propane + oxygen--->carbon (IV)  oxide + water
chemical  equation  is  as follows
  2C3H8  +7O2--->  3CO2  + 8 H2O
hence  2 moles  of propane  reacted with 7  moles  of  oxygen  to  give 3  moles of  CO2  and  8  moles  of  H2o

An atom of 14 6 c carbon decays by gamma decay which atom is left after the decay
ladessa [460]
Answer is: carbon.

<span>During gamma emission the nucleus emits radiation without changing its composition, if for example have nucleus with six protons and six neutrons (carbon atom) and after gamma decay there is nucleus with six protons and six neutrons.
Gamma rays are the electromagnetic waves with the shortest wavelengths (1 pm), highest frequencies (300 EHz) and highest energy (1,24 MeV).</span>

Anna [14]

Answer:

To meet the needs of the present without jeopardizing that of the future.

Explanation:

Sustainable development applies to all faculties of resource allocation. Most available resources are limited in their capacity to satisfy our limited human wants.

  • Sustainable development is such development geared towards satisfying the developmental needs of our present generation without endangering those of the future generations.
  • It allows for safe and efficient use/allocation of resources to meet wants.
  • Conservation of resources is an approach towards sustainable development.
  • The use of recycled materials is one method of attaining the obligations of sustainable development.

How many water molecules are produced when 5.2g O2 are reacted
gtnhenbr [62]

Answer:

Total number of water molecules produced after the reaction is 1.956×10^22 molecules of water.

Explanation:

By the reaction

H2+ 1/2 O2 → H2O

Moles of O2 = 5.2\32

⇒1 mole of O2 produce 1  mole of H2O

  1 mole O2 will produce 2 mole  of H2O

Therefore, 5.2\32 mole will produce {2}\times{\frac{5.2}\times{32}}

⇒ Molecules of H2O  will be

         {2}\times{\frac{5.2}{32}} = \frac{x}{{6.02}\times{10^23}}

= 1.956×10^22 moleculesof H2O.
