<span>To find the amount of heat energy required to raise a substance by a certain number of degrees, we simply multiply: (specific heat * change in temperature * mass)
Heat = 2.22 * 35 * 3 = 233.1 joules
Therefore, we would need 233.1 joules of heat to raise the temperature by 3 degrees Celsius.</span>
Answer:
C. NH₃
Explanation:
This buffer is formed by a weak base (NH₃) and its conjugate acid (NH₄⁺) which comes from the salt NH₄Cl. When an acid is added (hydrobromic acid) it is neutralized by the basic component of the buffer, according to the following equation.
NH₃(aq) + HBr(aq) ⇄ NH₄⁺(aq) + Br⁻(aq)
Methyle orange is the indicator that is used in sulfuric acid.
