Answer:

True

Explanation:

Polymer is made up of monomers. Monomers are the building block of polymers.

For example, formation of polyethylene from ethylene

H₂C=CH₂ + H₂C=CH₂ → - CH₂-CH₂-CH₂-CH₂-

Ethylene molecules add to one another through addition reaction.

When this reaction in equilibrium is heated, a red/brown color persists. what is true about this reaction? 2no2(

dimulka [17.4K]

NO₂ is a brown gas while N₂O₄ is colorless. If heating causes a brown color to persist, then this means that heating causes the reaction to shift backwards and produce NO₂. Therefore, the reaction must be exothermic.

$\qquad$ ☀️ $\pink{\bf{ {Answer = \: \: 85.57g }}}$

Molar mass of $\bf Cu_2O$

$\qquad$ $\twoheadrightarrow\sf 63.546 \times 2 +16$

$\qquad$ $\pink{\twoheadrightarrow\bf 143.092 g}$

<u>As we know</u>–

1 mol = $\bf 6.02×10^{23}$ formula units

1 mol $\bf Cu_2O$ = 143.092 g = $\bf 6.02×10^{23}$ formula units

Henceforth –

$\bf 3.60×10^{23}$ formula units $\bf Cu_2O$ –

$\qquad$ $\sf :\implies \dfrac{143.092 \times3.60×10^{23 }}{6.02×10^{23}}$

$\qquad$ $\sf :\implies \dfrac{143.092 \times3.60×\cancel{10^{23 }}}{6.02×\cancel{10^{23}}}$

$\qquad$ $\pink{:\implies\bf 85.57 g}$

Define in your own words: Solute, Solvent and Solution.

anyanavicka [17]

The substance that is being dissolved is called the solute and the substance that does the dissolving is called the solvent. So the solvent dissolves in the solute the forming a solution.
