Answer:
A. From 25,0 g of aluminium you will produce 0,927 moles of aluminium chloride
B. From 30,0 g of chlorine gas you will produce: 0,282 moles of aluminium chloride
Explanation:
a. The reaction that you have in this problem is:
3 Cl₂ + 2 Al → 2 AlCl₃
25,0 g of aluminium are:
25,0 ₓ
= 0,927 moles
As Al:AlCl₃ ratio is 1, from 25,0 g of aluminium you will produce: <em>0,927 moles of aluminium chloride</em>
b. 30,0 g of chlorine gas are:
30,0 ₓ
= 0,423 moles of Cl₂
As Cl₂:AlCl₃ ratio is ³/₂:
0,423 moles of Cl₂ ₓ
= <em>0,282 moles of aluminium chloride</em>
Thus, from 30,0 g of chlorine gas you will produce: <em>0,282 moles of aluminium chloride</em>
<em></em>

Answer:
Lactate dehydrogenase (LDH)
Explanation:
LDH is tetrameric enzyme found in the muscles (M-type) and the heart (H-type) of living cells, responsible for the conversion of pyruvate to lactate and back, to promote generation of nicotinamide adenine dinucleotide (NAD).
the scientific method allows to find the answers
1) it is not correct to show unmeasured points
2) extend the experiment or graphs without missing points
3) make the graphs without the missing points and analyze the curves
the scientific method is a set of rules and processes to ensure that an investigation is correct and is not influenced by the prejudices of the researcher
1) Science is based on experimental facts, with these facts it performs, tables, graphs, it postulates principles and laws, therefore it is not correct to include values that have not been measured experimentally.
2) In this experiment there are several observations
- Make the graph without these points, which are very few, has 34 experimental points and only 6 missing, this represents a small fraction
% missing = ![\frac{6}{40} \ 100](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B40%7D%20%5C%20100)
% missing = 15%
- Extend the study one more month to have more points and that the fraction of missing points decreases
3) If the researcher had presented the graph without the missing points, the sample that he has must already show the trend of the movement of the sun with respect to the days, making curves that fit the data.
In conclusion using the scientific method allows to find the answers
1) it is unethical to show unmeasured points
2) extend the experiment
3) make the graphs without the missing points and analyze the curves
