<u>Answer:</u> The organic compounds are C_2H_6\text{ and }CH_4

<u>Explanation:</u>

Organic compounds are defined as the compounds where a covalent bond is present between hydrogen and carbon atoms. These compounds are also known as hydrocarbons.

From the given options:

CO,CO_2\text{ and }NaCO_2 does not have a covalent bond between hydrogen and carbon atoms. Thus, these compounds are not considered as an organic compound.

C_2H_6\text{ and }CH_4 have a covalent bond present between hydrogen and carbon atoms. Thus, these are considered as organic compounds.

Hence, the correct answer is C_2H_6\text{ and }CH_4

Calculate the amount of heat needed to boil 183.g of ethanol ( CH3CH2OH ), beginning from a temperature of 33.9°C . Round your a
Shkiper50 [21]

Answer:

19,700 Joules

Explanation:

Quantity of heat (Q) = mc(T2-T1)

m (mass of ethanol) = 183g

c (specific heat capacity of ethanol) = 2.44J/g°C

T2 (boiling temperature of ethanol) = 78°C

T1 (initial temperature of ethanol) = 33.9°C

Q = 183×2.44(78 - 33.9) = 183×2.44×44.1 = 19691.532 = 19,700 Joules (to three significant digits)

Prepare a journal about the topic Water-The Life Giving Liquid
Alex

Water is known as a life-giving liquid because every living organism depends on the water for its survival.

<h3>Journal about the topic Water-The Life Giving Liquid</h3>

Water is also called a life-giving liquid because without water life on earth is not possible. All other living organisms need to consume water to survive and grow in size. We need water for many other activities such as cleaning, washing, cooking and irrigation. Water is essential for all living things including humans, animals and plants. Water is called wonder liquid as it can dissolve large number of substances. This property enables water to be a great solvent. Most of the chemical reactions of the living world is carried out in water as a medium so that's why water is known as Life Giving Liquid.

So we can conclude that Water is known as a life-giving liquid because every living organism depends on the water for its survival.

  • A researcher anyone who has restricted equipment and materials to finish an investigation might cooperate with certain other scientists as well as establish networking to exchange resources, thoughts, and behaviors for the survey's completion.

<u>Adjust this same scale and complexity of the investigation:</u>

  • To decrease costs, the researchers might measure the study up by decreasing the levels initially intended for the investigation.

How many molecules of NH3 are produced from 8.01x10-4g of H2
lara31 [8.8K]

Answer:

1.61 x 10²⁰ molecules

Explanation:

Given parameters:

Mass of the hydrogen gas  = 8.01 x 10⁻⁴g

Unknown

Number of molecules of NH₃ = ?

Solution:

Given reaction:

                     N₂  +  3H₂   →   2NH₃

We have to solve from the known to the unknown

  • The known specie is the mass of H₂ ;

             find the number of moles of the specie;

    number of moles = \frac{mass}{molar mass}

     Molar mass of H₂ = 2(1) = 2g/mol

   Number of moles  = \frac{0.0008}{2}   = 0.0004mol

  • 3 moles of H₂   will produce 2 moles of NH₃

      0.0004 moles of H₂ will produce \frac{0.0004 x 2}{3}   = 0.00027moles of NH₃

   1 mole of a substance contains 6.02 x 10²³ molecules

     0.00027mole of NH₃ will contain 0.00027 x 6.02 x 10²³

                               = 1.61 x 10²⁰ molecules
