Answer:
The correct equation to calculate the heat of this reaction is:
ΔH = m*s*∆T
Explanation:
During any chemical reaction, heat can either be absorbed from the environment or released to the environment through the reaction. The heat exchange between a chemical reaction and its environment is known as the reaction enthalpy, or H. However, H cannot be measured directly; the change in temperature of a reaction over time is used to find the enthalpy change over time (denoted as ΔH).
In general ΔH = m*s*∆T, where m is the mass of the reactants, s is the specific heat of the product, and ΔT is the change in the reaction temperature.
it is either "aweak acid or a lousy (or very weak) acid"
Answer:
Density = 7.11 g.cm⁻³
Solution:
Density is given as,
Density = Mass / Volume --------- (1)
Data Given;
Mass = 32 g
Volume = 16.8 mL - 12.3 mL = 4.5 mL = 4.5 cm³
Putting values in equation 1,
Density = 32 g / 4.5 cm³
Density = 7.11 g.cm⁻³
