According to the FDA, products labeled gluten-free must contain less than 20 milligrams of gluten
Answer:
Explanation:
Remark
CH2 provides the basic structure of the hydrocarbon. It will be multiplied by some factor determined by the number of grams / mol. I will use rounded numbers because all periodic tables are slightly different.
Theoretical mass of CH2
1 C = 1 * 12 = 12
2 H= 2 * 1 = 2
Mass CH2 = 14
The multiplier for CH2
56.108 rounded = 56
Multiplier = molar mass (rounded)/Mass CH2
Multiplier = 56/14 = 4
Chemical
(CH2)_4 = C4H8
Answer: C4H8
<span>Generally negative ions is known as anion and positive ions is known as cation. Anions will gain an electron to fill in an electron shell but cations will lose an electron to fill in an electron shell so that cation by losing the electron the ionic mass will be lower where as for anion by gaining an electron the ionic mass will be higher so that atom will be larger.Therefore negative ions tend to be larger than positive ions.</span>
A) Salt, because salt can easily dissolve in water. Oil would not dissolve or evaporate in water (think of an oil spill - does that oil dissappear?). Aluminum foil would definitely not dissolve in water, so it is not soluble.
It condenses very long strings of numbers while retaining the general accuracy of the figure.
