<span>Tums are great antiacid tablets for heartburn and indigestion. Calcium carbonate is a great chemical to treat these conditions. If it were not for calcium carbonate, then many people would have heartburn for years until they eventually died from the condition unfortunately.</span>
Answer:
1.840 x 10⁻³ mol HBrO₃
Explanation:
To find the moles of bromic acid (HBrO₃), you should (1) convert milligrams to grams (by dividing by 1,000) and then (2) convert moles to grams (via molar mass from periodic table).
Molar Mass (HBrO₃): 1.008 g/mol + 79.904 g/mol + 3(15.998 g/mol)
Molar Mass (HBrO₃): 128.906 g/mol
2.372 x 10² mg HBrO₃ 1 g 1 mole
---------------------------------x----------------x------------------ = 1.840 x 10⁻³ mol HBrO₃
1,000 mg 128.906 g
Cyclohex<u>ene</u> is a cyclic, six-membered hydrocarbon that contains one double bond. The types of reactions that can occur in cyclohexene would be those that are typical with alkenes generally.
The pi-bonded electrons in the double bond are nucleophilic. So, electrophilic addition reactions could occur with cyclohexene. For example,
cyclohexene + HBr → bromocyclohexane
cyclohexene + H2O/H+ → cyclohexanol
cyclohexene + Br2 → <em>trans-</em>1,2-dibromocyclohexane (racemic)
The latter is a common test for alkenes where one adds bromine to a sample to see if there is decolorization, which would indicate the presence of nucleophilic pi bonds. Bromine, which is dark reddish-brown, will become clear as it reacts with an alkene to form a colorless haloalkane.
Cyclohexene can also be converted to the fully saturated cyclohexane by hydrogenation: cyclohexene + H2/Pd → cyclohexane.

This is due to the fact that the oxygen atom in water also contains two lone pairs of electrons.
