Answer:
4.2moles
Explanation:
"The answer to your question is 4.2 moles of H₂O
Explanation:
Data
moles of H₂O = ?
moles of C₂H₆ = 1.4
Balanced chemical reaction
2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O
Process
To determine the moles of H₂O, use proportions and the coefficients of the balanced chemical reaction.
2 moles of C₂H₆ 6 moles of H₂O
1.4 moles of C₂H₆ x
x = (1.4 x 6) / 2
x = 8.4/2
x = 4.2 moles of H₂O"
Synthetic fabrics<span> are </span>textiles made<span> from man-</span>made fibers<span> rather than natural </span>fibers. Chemically produced fabrics<span> are </span>made<span> by joining monomers into polymers, through a process called polymerization. A </span>synthetic fabric<span>, when magnified, looks like plastic spun together.</span><span>
Natural fabrics, such as cotton, silk, and wool, are made from animals or plant based fibers. While synthetic are man made and produced entirely from chemicals to create fabrics. such as polyester, rayon, acrylic, and more. The benefits of using textiles made from synthetic fibers is that it saves the animals and plants that the fibers are based off of.

Urban areas are crowded places with many apartments, offices, restaurants, parking lots and shopping centers. Comparing the amount of dirt, wastages and pollutants that are released into streams and lakes by each of these sources, we can conclude that the construction of a shopping mall or parking lot contributes a lot to the addition of the wastage into the streams and lakes
A shopping mall and parking lot in itself occupies a lot of space hindering the air balance and also increasing the traffic in the area and the adjacent areas leading to this area. On the other hand , this construction accommodates hundreds of shops that discards bulks of packaging materials in the form of plastic covers, fabric, card boards and other wastages which will have to be dumped every day.
Apart from this, urban areas have major part of the land covered with roofs and roads thus making all the rain water flow into the sewer and drainages washing out chemical wastes, pet wastes and other garbages into the streams and lakes.
Answer:
Somatic nervous system
Explanation:
The peripheral nervous system is categorised into two division: the somatic and autonomic.
The autonomic nervous system is the division which controls the autonomic function of the body whereas the somatic nervous system is the system which controls the voluntary functions of the body.
The somatic nerves transmit the signal from the skin, muscle and joints to the CNS and from CNS to the effector's muscles.
Thus, Somatic nervous system is the correct answer.
