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.
Mass percentage is one way of representing the concentration of an element in a compound or a component in a mixture. To calculate percent by mass, you need to determine two things: the mass of just the element, and the molar mass of the whole compound. We calculate as follows:
.10 g NaCl / g NaCl + Water = ( 10.0 g NaCl + x ) / (10.0 g + 255 g + x )
x = 18.33 g NaCl needed
Hello there!
The solute is salt, and the solvent is water. So the answer is #1.
