Answer:4.5 moles of sulfate ions are present in 1.5 moles of .
Explanation:
1 mol of gives 3 moles of sulfate ions.
Moles of sulfate ion in 1.5 moles :
4.5 moles of sulfate ions are present in 1.5 moles of .
Moles are the fraction of the chemical unit of the atoms, molecules, etc. The moles of sulfate ion present in 1.5 moles of aluminum sulfate is 4.5 moles.
Moles are the ratio of the mass of the substance to that of the molar mass of the substance. Moles are given in mol.
The reaction can be shown as:
From the reaction, it can be concluded that 1 mole of aluminum sulfate will give 3 moles of sulfate ions.
The moles of sulfate ions in 1.5 moles of aluminum sulfate will be,
Therefore, 4.5 moles of sulfate ions are present in aluminum sulfate.

Which best describes the purpose and outcome of the demonstration?
Since you couldn't even put the answer choices down, i'll give the unfortunate viewers who are confused, the answer.
It is C) Boyle's law since it is showing the relationship between pressure and volume.
Answer:
The correct answer is red-sensitive nerves.
Explanation:
The individuals with protanopia do not possess the tendency to sense red light, the individuals with tritanopia do not sense blue light, and the individuals with deuteranopia do not sense green light. If an individual is perceiving green color then in that case, the yellow sensitive nerves must function somewhat efficiently as green is an amalgamation of blue and yellow. Thus, the red-sensitive nerves would not be reacting appropriately for this individual.
Final answer:
142 nutritional calories (Cal) are equal to 142,000 calories (cal) since one nutritional Calorie is equivalent to 1000 scientific calories (cal).
Explanation:
To convert 142 nutritional calories to calories, you need to understand the relationship between the two units. In nutrition, when we say 'calories', we actually mean 'kilocalories' (kcal). One nutritional calorie (with an uppercase C) is equal to one kilocalorie (kcal), and one kilocalorie is equivalent to 1000 calories (with lowercase c).
Therefore, 142 nutritional calories (Cal) are equivalent to 142,000 calories (cal).
The conversion formula is as follows:
142 Cal * 1000 = 142,000 cal

Na- 11=22
H-1 =1
C-12=12
O3=16*3 =48
total = 22+1+12+48 = 83
83-----> 48
100-----> 100*48/83=57.83 = 57.13 is nearest answer
