Answer:
a. acid
Explanation:
- The neutralization of a base requires the addition of acid.
- Hydroxide ions of the base are neutralized using hydrogen ions of an acid.
- Acid-base neutralization results in the formation of water and salt.
For example: NaOH is neutralized by HCl as:
<em>NaOH + HCl → NaCl + H₂O.</em>
Answer:
The specific heat for the titanium metal is 0.524 J/g°C.
Explanation:
Given,
Q = 1.68 kJ = 1680 Joules
mass = 126 grams
T₁ = 20°C
T₂ = 45.4°C
The specific heat for the metal can be calculated by using the formula
Q = (mass) (ΔT) (Cp)
Here, ΔT = T₂ - T₁ = 45.4 - 20 = 25.4°C.
Substituting values,
1680 = (126)(25.4)(Cp)
By solving,
Cp = 0.524 J/g°C.
The specific heat for the titanium metal is 0.524 J/g°C.
