The correct answer among the choices given is option A. Hydrochloric acid is a much stronger acid than sulfuric acid given that the concentration both is equal. This can be proved by the pKa of these acids. Hydrochloric acid has a pKa of -6 while the pKa of sulfuric acid is -3. The lower the value of the pKa, the stronger the acidity of the substance.
Answer:
Isotopes are forms of a chemical element that have the same atomic number but differ in mass. 16O → 8 protons + 8 neutrons; a “light” oxygen); The relative amounts are expressed as either 18O/16O or δ 18O Oxygen - 18 (aka 18O → 8 protons + 10 neutrons; a “heavy” oxygen).
Answer:
A) It is a practical source of energy on Earth.
Explanation:
The reaction shown is a nuclear fusion reaction. Nuclear fusion refers to the combination of two light nuclei to produce a heavier nuclei with a release of tremendous amount of energy. The energy released in a fusion reaction is so great and it is often difficult to achieve fusion reactions in a controlled nuclear reactor.
Fusion reactions just like the one shown is the source of energy on earth. The energy reaching the earth is obtained by fusion reactions in outer space.
