Answer:
1.The diagram is attached
2.sodium alginate is a polymer which can be extracted from brown seaweed and is used for defloculating, gelling and thickening
Used also in dermatological preparation
Used in adhensive paste
Moles ratio:
1 S<span> + 1 </span><span>O2</span><span> = 1 </span><span>SO<span>2
</span></span>
1 mole S -------------- 1 mole SO2
? moles S ------------ 0.567 moles SO2
0,567 x 1 / 1
= 0.567 moles of S
Answer: The correct answer is "Mechanical waves can apply pressure to and push on objects in their path".
Explanation:
Mechanical wave is wave in which there is an oscillation of the wave. The energy is transferred through a medium. Mechanical waves can apply pressure to and push on their path. Only the energy is transferred not the matter.
Mechanical waves are of three types: Transverse wave, Longitudinal wave and Surface wave. The examples of the mechanical wave are sound wave and water wave.
Sound is a pressure disturbance which travels through a medium. It consists of compression and rarefaction.
The mechanical waves need a medium for their propagation. They travel faster in denser medium.
Therefore, the correct option is (B).
Answer:
Explanation:
In one of the process, energy is built up from scratch, in the other one, energy is liberated for use by an organism or body.
The first process deals with a metabolic reaction in which energy is liberated:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
In the above process, energy is liberated when glucose combines with oxygen. The waste products are carbon dioxide and water. This process liberates heat energy which can be used to do work.
In the reverse process:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
This process stores energy in carbon chains as chemical energy. It is this energy that is released in the first process.
Therefore, we can see that the first process liberates energy and the reverse process stores energy.
Answer:
Corn starch, one of the covalent compounds, is solid at room temperature. The property of being solid is more common to ionic compounds. So, the hypothesis was mostly supported except for this one data point.
