saveliy_v [14]3 years ago

Answer:

Your question seems to me that it is somewhat poorly written, but it could help you by telling you that by increasing the collision of the individuals, the friction between them increases, therefore increasing the release of energy in the form of heat and thus increasing the temperature.

Therefore, the hypothesis raised would be correct.

Explanation:

If the shock is perfectly inelastic (plastic), the kinetic energy is not conserved and, as a consequence, the colliding bodies can undergo deformations and increase in temperature.

BASED ON THE INFORMATION BELOW. CALCULATE THE MASS FOR ONE OF THESE ATOMS:
stepladder [879]

C = 12 g

O = 16 g

H = 1 g

<h3>Further explanation </h3>

Conservation of mass stated that  

<em>In a closed system, the masses before and after the reaction are the same </em>

we can calculate the mass of each atom in the compound :

O in O₂ :

mass O₂ = 32

mass O = 32 : 2 = 16 g

H in H₂O

mass H₂O = 18

mass 2.H + mass O = 18

mass 2.H + 16 = 18

mass 2.H=2

mass H = 1 g

C in CH₄

mass CH₄ = 16

mass C + mass 4.H = 16

mass C + 4.1=16

mass C = 12 g

or we can use formula :

Mass of a single C :

\tt =\dfrac{Ar~C}{MW~CO_2}\times mass~CO_2\\\\=\dfrac{12}{44}\times 44=12

Answer:

                    Polyatomic Ionic Compound

Explanation:

                     In given statement the compound given is called as Sodium oleate this means that when Oleic acid is treated with NaOH then it forms.

                     In chemistry there are few species which are involved in the formation of compounds.

  (i) Atoms:

                  It is very common that atoms of different elements combine to form compound through covalent bond. For example, H₂, O₂, N₂, F₂ e.t.c.

   (i) Ions:

                  Other than covalent compounds we have ionic compounds. Ionic compounds are made up of ions. These ions forming the ionic compounds can be monatomic like Na⁺, Br⁻, Mg²⁺, Al³⁺, N⁻³ or they can be polyatomic like CO₃²⁻, SO₄²⁻, NH₄⁺, PO₄³⁻ e.t.c.

    (iii) Polyatomic Ions:

                                     In polyatomic ions we find a charge on a molecule which contains two or more atoms bonded covalently. Hence, in given compound we have a long chain of molecule containing a negative charge neutralized by opposite +ve charged sodium ion. Hence, Sodium oleate is a polyatomic ionic compound.
