Answer:
14.8% of H2O2
Explanation:
Based on the redox reaction of H2O2/MnO4- is:
2MnO4- + 5H2O2 + 6H+ ⇄ 2Mn2+ + 5O2 + 8H2O
<em>2 moles of KMnO4 react with 5 moles of H2O2</em>
<em />
To solve this question we need to find the moles of KMnO4 until reach the endpoint. Using the balanced reaction, we can find the moles of H2O2 that must be converted to grams using its molar mass -Molar mass H2O2: 34.015g/mol-:
<em>Moles KMnO4:</em>
0.0297L * (1.4686eq/L) = 0.04362eq MnO4- * (1mol / 5eq) = 0.008723 moles MnO4-
<em>Moles H2O2:</em>
0.008723 moles MnO4- * (5mol H2O2 / 2mol MnO4-) = 0.02181 moles H2O2
<em>Mass H2O2:</em>
0.02181 moles H2O2 * (34.015g/mol) = 0.7418g H2O2
<em>%:</em>
0.7418g H2O2 / 5.0mL * 100
<h3>14.8% of H2O2</h3>
Answer:
b. Cellulose acetate
Explanation:
Cellulose acetate is acetate ester of the cellulose.
The material was first prepared in 1865. It is used as film base in the photography as component in coatings and also as frame material for the eyeglasses. Also, it is used as synthetic fiber in the manufacture of the cigarette filters and also in playing cards. It is used because it is far less flammable and also cheaper to produce. <u>It provides support and stiffness to the X-ray film and further helps in producing good results.</u>
Newly graduated m.d.s choosing to specialize in internal medicine, family practice, or paediatrics require a three years residency program.
The length of your residency training is determined by the speciality you choose. The shortest residency programs are in primary care, while the longest is in surgery. Newly graduated m.d.s choosing to specialize in internal medicine, family practice, or paediatrics require a three years residency program.
Regardless of your residency program length, your sense of independence, responsibility, and autonomy grows with every year of residency until you are operating independently in your desired field by the close of your residency program. All residency areas of expertise also provide the option for additional specialization following residency, known as fellowship training.

Accumulation of secretions in the client's lungs should be the reaction of the nurse.
What is an endotracheal tube?
The endotracheal tube, in its most basic form, is a polyvinyl chloride tube inserted through the trachea and between the vocal cords. It serves to nourish the lungs with oxygen and other inhaled gases while shielding them from contaminants like stomach juices or blood.
The major functions of a tracheal tube, which is a catheter put into the trachea, are to create and maintain a patent airway and to ensure that there is an appropriate exchange of oxygen and carbon dioxide.
Hence the answer is the accumulation of secretions in the client's lungs.
