I am pretty sure the answer is A
Answer with explanation:
1) general word equation=acid + metal= salt + hydrogen gas
chemical/balanced equation= 2HCl+Mg=MgCl2+H2
2)The gas thus formed is an effervescent carbon di oxide when calcium chloride reacts with hydrochloric acid. the carbon di oxide gas also acts as an extinguisher for fires. Hence the burning candle is extinguished.
Answer:
1.345*10⁻⁴ mol/L
15.023 mg/L
Explanation:
The chemical <u>formula of ferrocene</u> is Fe(C₅H₅)₂, thus its molecular weight is:
55.845 g/mol + 10*12g/mol + 10 *1g/mol = 185.845 g/mol
- The moles of Fe contained in 25 mg (or 0.025 g) of ferrocene are:
- The final volume is 500 mL, or 0.5 L. So the iron concentration in mol/L is:
- We can convert that value into mg/L:
Answer:
Epoxides, also called oxiranes, have a three-membered ring structure with one oxygen and two carbon atoms.
Epoxides can be formed from alkenes by reaction with peroxy acids (MCPBA for example).
Epoxides can be formed from halohydrin molecules by reaction with a base, which causes an intramolecular Williamson ether synthesis.
Explanation:
Epoxide, cyclic ether with a three-membered ring. The basic structure of an epoxide contains an oxygen atom attached to two adjacent carbon atoms of a hydrocarbon. The strain of the three-membered ring makes an epoxide much more reactive than a typical acyclic ether.
Nuclear reaction involves two reacting particles a heavy target nucleus and a light bombarding particle and produces two new particles a heavier product nucleus and a lighter ejected particle.
