Answer: A. Internal energy : May be viewed as the sum of the kinetic and potential energies of the molecules
B. Latent heat: The internal energy associated with the phase of a system.
C. Chemical (bond) energy : The internal energy associated with the atomic bonds in a molecule
D. Nuclear energy : The internal energy associated with the bonds within the nucleus of the atom itself
Explanation:
Internal energy is defined as the total energy of a closed system. Internal energy is the sum of potential energy of the system and the kinetic energy of the system. It is represented by symbol U.
Latent heat is the thermal energy released or absorbed by a thermodynamic system when the temperature of the system does not change. It is thus also called as hidden heat.
Chemical energy is the energy stored in the bonds of molecules.
Nuclear energy is the energy which is stored in the nucleus of an atom called as binding energy within protons and neutrons.
Answer:
V = 85.2
Explanation:
STP = 273K and 1 atm
Considering what we know about STP, we get the moles, temperature, and pressure. Using the ideal gas law we can find the volume (PV = nRT). Plug in our variables: (1 * V = 3.80 * R * 273). Since we are dealing with atm and not kPA or mmHg, we use the constant for atm (0.0821) which we use for R. (So.. now our equation is 1 * V = 3.80 * 0.0821 * 273). We now multiply the right side to get 85.17054. So... V = 85.2 considering sigificant figures (this is the part where I am the least sure of, since I havent done sig figs in a while)
Li is in group 1 so it has same number of valence electrons as hydrogen.
hope it helps.
Hi! :)
Ba(OH)2 + 2 HNO3 → Ba(NO3)2 + 2 H2O
(18.2 mL) x (0.45 M Ba(OH)2) x (2 mol HNO3 / 1 mol Ba(OH)2) / (38.5 mL HNO3) = 0.43 M HNO3
