It will stick to the body because a synthetic fibre has the property to cohere with the substance.
In this case substance is our skin. After having a burn, the Rayon will stick to the skin.
And if it has a lesser quality then it will make your skin melt.
Hope helps ...
Answer:
The answer is
<h2>1.33 cm³</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 3.46 g
density = 2.60 g/cm³
The volume is
We have the final answer as
<h3>1.33 cm³</h3>
Hope this helps you

<u>Step 1: Define</u>
2.3 × 10²⁴ formula units KNO₃
<u>Step 2: Identify Conversions</u>
Avogadro's Number
Molar Mass of K - 39.10 g/mol
Molar Mass of N - 14.01 g/mol
Molar Mass of O - 16.00 g.mol
Molar Mass of KNO₃ - 39.10 + 14.01 + 3(16.00) = 101.11 g/mol
<u>Step 3: Convert</u>
<u /> = 386.172 g KNO₃
<u>Step 4: Check</u>
<em>We are given 2 sig figs. Follow sig fig rules and round.</em>
386.172 g KNO₃ ≈ 390 g KNO₃
Answer:
K = 8x10¹⁸
Explanation:
<em>When you sum a reaction, the result of this sum has a K equal to the multiplication of the K's of the reactions involved in the sum</em>
<em />
The sum of two times the reaction:
NaO(g) ⇌ Na(l) + 1/2 O₂(g) K₂ = 2x10⁻⁵
2 NaO(g) ⇌ 2 Na(l) + O₂(g) K = K₂ₓK₂ = (2x10⁻⁵)² = 4x10⁻¹⁰
The result of the inverse reaction:
Na₂O₂(s) ⇌ 2 Na(l) + O₂(g) K₃= 5x10⁻²⁹
2 Na(l) + O₂(g) ⇌ Na₂O₂(s) K = 1/K₃ = 2x10²⁸
And the sum of the two bolded reactions:
2 NaO(g) + 2 Na(l) + O₂(g) ⇌ 2 Na(l) + O₂(g) + Na₂O₂(s)
2 NaO(g) ⇌ Na₂O₂(s) K = 4x10⁻¹⁰× 2x10²⁸
<h3>K = 8x10¹⁸</h3>
