Jupiter’s moon io was discovered to have high concentrations of sulfur oxides in its atmosphere. this, in combination with resea

rch into sulfur oxides relating to pollution on earth, has led to renewed interest in sulfur oxide compounds. one compound discovered on io was the blue disulfur trioxide. write the chemical formula for this compound.

Answer:

S_2O_3

Explanation:

Hello,

Nomenclature, is a powerful tool in chemistry to name chemical compounds to successfully distinguish among the thousands and thousands of existing molecular compounds. In rule to stipulate a chemical name y is via specifying the amount of the composing elements into the molecule, thus, the prefix <em><u>di</u></em>, accounts for two atoms and the prefix <u><em>tri</em></u> for three (this is related with the valence electrons the element has), in such a way, disulfur trioxide is represented with two sulfur atoms and three oxygen atoms, this is:

S_2O_3

Which would be a novel molecule since the sulfur has been reported to have +2,+4 and +6 as the positive oxidation states which are possible to dovetail with oxygen as it is negative.

Kind regards.

Answer:

they're losing electrolytes

Explanation:

When athletes sweat, they're losing electrolytes primarily in the form of sodium (Na+) and chloride (Cl-), so when you start to replace lost fluids, ahtletes should replace the electrolytes as well. Potassium (K+), Magnesium (Mg2+) and Calcium (Ca2+) are electrolytes also lost through sweating.

Epinephrine (adrenaline) is a hormone secreted into the bloodstream in times of stress. It contains 59.0% C, 7.15% H, 26.20% O,
vichka [17]

Answer:

C9H13O3N

Explanation:

Take the atomic mass of C=12.0, H=1.0, O=16.0 and N=14.0.

We can draw a chart (please view this on desktop so to avoid spacing errors):

Let the mass of Epinephrine be 100g.

                             C                       H                          O                              N

mass(g) :              59                      7.15                    26.2                         7.65

no. of moles : 59/12 =4.9167     7.15/1 = 7.15     26.2/16=1.6375 7.65/14=0.5464

(n.o.m. = mass/molar mass)

Ratio:   4.9167/0.5464 =9    7.15/0.5464=13      1.6375= 3      0.5464/0.5464 =1

(divide the n.o.m. by the smallest n.o.m., which is 0.5464 in this case, take the whole numbers)

So, the empirical formula will be: C9H13O3N

But this is still not yet the molecular formula. We have to ensure the molar mass is 183g/mol. Multiply the empirical formula by n.

So, let the molecular formula of Epinephrine be (C9H13O3N)n.

12x9n + 1x13n + 16x3n + 14n = 183

108n + 13n + 48n + 14n = 183

183 n = 183.

n = 1

Hence, the molecular formula is C9H13O3N.
