Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the drawing referred to in the question.
However, each option refers to a particular respiratory system and with the organs and the tissues mentioned here one can eventually identify which option is correct when the drawing is available.
A) The system described here is the cardiovascular system (or the circulatory system). This system involves the heart, blood vessels and the blood (which are what help in the transport of the materials mentioned in the question).
B) The system described here is the digestive system. This system involves the gastrointestinal tract and organs (that assist in the production/secretion or storage of chemicals that breakdown food into smaller pieces) such as the mouth, esophagus, stomach, small intestine, large intestine, rectum and the anus.
C) The system described here is the skeletal system. This system involves all the bones and joint in the body (the skeleton) which also helps in protecting organs in the body.
D) The system described here is the Endocrine system. This system involves several internal glands (such as the thyroid gland and the adrenal glands) in the body.
NOTE: Identify which organ and/or tissue is present in the diagram and use that to select the appropriate option from the description of each of the options provided above.
Mass of ammonia produced : 121.38 g
<h3>Further explanation</h3>
Given
Reaction
3H₂(g) + N₂(g) ⇒ 2NH₃(g)
100g of N₂
Required
Ammonia produced
Solution
mol of N₂ :
From the equation, mol ratio of N₂ and NH₃ = 1 : 2, so mol NH₃ :
mass of NH₃(MW=17 g/mol) :
The black fur absorbs all the colors where the white fun reflects all the colors because we see the green grass it absorbs all the colors except green and the yellow dandelion is reflecting yellow and orange because it’s color is like a mix of them but it still absorbs the other colors
Answer:
No, there is no evidence that the manufacturer has a problem with underfilled or overfilled bottles, due that according our results we cannot reject the null hypothesis.
Explanation:
according to this exercise we have the following:
σ^2 =< 0.01 (null hypothesis)
σ^2 > 0.01 (alternative hypothesis)
To solve we can use the chi-square statistical test. To reject or not the hypothesis, we have that the rejection region X^2 > 30.14
Thus:
X^2 = ((n-1) * s^2)/σ^2 = ((20-1)*0.0153)/0.01 = 29.1
Since 29.1 < 30.14, we cannot reject the null hypothesis.
When you add heat to a solid the particles gain energy and start to vibrate faster and faster.
When you add heat to a liquid the particles are given more energy and move faster and faster expanding the liquid.
