Answer:

The correct answer will be option-gravitational energy.

Explanation:

The gravitational force is the attractive force which exists between two objects with mass. This attractive force directly influence the other object as it helps maintain the object in the universe.

When one of the objects out of two is earth, the force is termed as gravity or it is the force with which the earth attracts the object.

The gravity is directly proportional to mass due to which the earth will attract the object with stronger force. When the object will be present at the height the strongest force applied on the object will be the gravitational force.

Thus, gravitational energy is the correct answer.

Please help me with this basic organic conversion.<br>use the shortest way to do it​
jonny [76]

Answer:

See explanation

Explanation:

This conversion must go through a sequence of steps as i have shown in the image attached to this answer.

The acetone is converted to propan-2-ol using LiAlH4, THF and acid. The  propan-2-ol may be converted to propene by E2 elimination. Addition of HBr yields 2-bromo propane.

The Wurtz reaction converts 2-bromo propane to 2,3- dimethyl butane. This can be brominated in the presence of light to yield 3-bromo-2,3-dimethyl butane. Elimination of HBr using a base leads to the formation of the required product as shown.

How many grams of water are produced when 35.8 grams of Calcium hydroxide reacts with lots of Hydrochloric acid?
Veseljchak [2.6K]

Are produced 72 grams of water in this reaction.

<h3>Mole calculation</h3>

To find the value of moles of a product from the number of moles of a reactant, it is necessary to observe the stoichiometric ratio between them:

                          Ca(OH)_2 + 2HCl = > 2H_2O + CaCl_2

Analyzing the reaction, it is possible to see that the stoichiometric ratio is 1:2, so we can perform the following expression:

MM_{Ca(OH)_2} = 74.1g/mol

                                           MM = \frac{g}{mol}

                                             74.1 = \frac{35.8}{mol}\\mol = 2

So, if there are 2 mols of Ca(OH)2:

                                  Ca(OH)2    |    H2O

                                          \frac{1mol}{2mol} =\frac{2mol}{xmol}

                                             x = 4mol

Finally, just find the number of grams of water using your molar mass:

MM_{H_2O} = 18g/mol

                                              18= \frac{m}{4}\\m = 72g

So, 72 grams are produced of water in this reaction.

What mass of water must be used to make a 1.35 m solution that contains 8.20 mol NaOH?
Sergeeva-Olga [200]
Answer is: <span>mass of water is 6.07 kilograms.
</span>b(NaOH) = 1.35 m.
n(NaOH) = 8.20 mol.
b(NaOH) = n(NaOH) ÷ m(H₂O).
m(H₂O) = n(NaOH) ÷ b(NaOH).
m(H₂O) = 8.20 mol ÷ 1.35 mol/lg.
mm(H₂O) = 6.07 kg.
m - molality.
n - amount of substance.
