Using this formula E = mc2, which is the formula formulated by Albert Einstein to get the energy where E is the units of energy, m is the mass and c is the speed of light. We can say that 1 g is equivalent to 0.001 kg. The speed of light is 38<span>. Substituting these values to the formula, we can get 90 terajoules.</span>
Answer:
Judges and justices serve no fixed term — they serve until their death, retirement, or conviction by the Senate. By design, this insulates them from the temporary passions of the public, and allows them to apply the law with only justice in mind, and not electoral or political concerns.
Answer:
Explanation:
The number of moles of solute is equal to product of the molar concentration (molarity) and the volume (in liters) of solution.
Since the volumes and the molar concentrations of the<em> NaOH </em>and <em>HCl </em>solutions mixed are equal, each one of them contributes the same number of moles of solute.
Since every mol of NaOH produces one mol of OH⁻ ions and every mol of HCl produces one mol of H⁺ ion, the number of moles of OH ⁻ and H⁺ in solution are equal.
Thus, OH⁻ and H⁺ ions will be neutralized by the reaction:
- OH⁻ (aq) + H⁺ (aq) ⇄ H₂O (l)
Which is strongly shifted to the right and has <em>neutral pH</em>.
Hence, you conclude that the approximate <em>pH of the solution is neutral.</em>
Answer:
The pH o.s the s.u.b.st.a.n.c.e is 1,92.
Explanation:
pH = -log (H +)= -l.o.g (1.2 x 10^-2 )=1,92
