A hydrogen bond is formed by attraction between + and - charges on different water molecules.
Basically, it is the bond between two atoms that already participate in other chemical bonds. Hydrogen bonds may form between atoms within a molecule or between two separate molecules.
You just need to convert the mass in grams to number of moles and use the ideal gas equation, pV = n RT
where p = 100 kPa, T = 273 K, V is the volume searched, n is the number of moles and R is the unviersal constant of gases = 8.314 J / K * mol
1) Number of moles = mass in grams / molar mass
=> n = 32.7 g / 18.0 g/mol = 1.81667 moles
2) pV = nRT => V = nRT / p
V = 1.81667 moles * 8.314 (liter*KPa /k*mol) * 273K / (100 KPa) = 41.2 liter
Answer: 41.2 liters
The mass of an atom is given by the sum of the number of PROTONS and the number of NEUTRONS since ELETRON'S mass is negligible.
The mass is 24+28 = 52.
Answer:
B products, reactants
Explanation:
The energy of the reactants is the leftmost letter on the graph given by A, and the energy of the products are given by the rightmost letter on the graph, C.
C is higher in energy than A since it is higher on the diagram, and thus it has more energy. This means the products have more energy than the reactants.
