During cellular respiration, chemical energy is converted to cellular energy. (2 points) <u>True</u> False
It is a process of oxidation of glucose to produce large amount of energy along with carbon dioxide and water
Answer:
B and D could be true
Explanation:
A volume of sodium hydroxide less than expected could occurs for two reasons:
The real concentration of sodium hydroxide was higher than expected or the amount of vinegar added was less than expected:
A. The sodium hydroxide solution had been allowed to stand exposed to the air for a long time prior to the titration. FALSE. A long expose to the air decreases concentration of the NaOH.
B. The volumetric flask used to prepare the diluted vinegar solution was rinsed with water prior to use. TRUE. You add a less amount of vinegar doing you require less amount of NaOH than expected.
C. The burette used to deliver the sodium hydroxide solution was rinsed with water prior to use. FALSE. Thus, you add a less amount of NaOH than expected. To explain the matter, you add more NaOH than expected.
D. The pipette used to deliver the vinegar solution was rinsed with water prior to use. TRUE. Again, you are adding a less amount of Vinegar than expected doing the necessary NaOH during titration less than expected
The rinsing of mouth is to remove food particles and minimize mucous
<u>Complete Question:</u>
Which of the following is not a characteristic of electromagnetic waves?
a. they can travel through a vacuum.
b. they can travel at various speeds through any one material.
c. they can be refracted.
d. they can be reflected.
<u>Correct Option:</u>
"They can travel at various speeds through any one material" is not a characteristic of electromagnetic waves.
<u>Explanation:</u>
It is a form of energy generated by interference from the oscillating magnetic and electric recorded. So we may conclude that it is created by moving electric charged particles through the vacuum so matter. This is a wave in which the two vectors vibrate each other perpendicularly and in the direction of the wave. Electromagnetic waves which involve gamma-rays, x-rays, ultraviolet rays, infrared-rays, microwaves and radio-waves can be featured by:
- They may pass through the vacuum.
- They are allowed to move through the matter and are reflectable.
- They can pass through all of the material at the same pace. This means there is still constant speed of light, which is, they can be refracted.
