Depends on how the sword is made, what materials are used and temperature used but yes they can shatter.
When molecules cool down they stop vibrating and moving as much and so they "shrink" and the metal of the sword becomes brittle. sometimes they shrink at different phases which cause tension in the sword if this tension is strong enough it can cause the metallic bonds to break causing the sword to shatter.
hope that helps

58.44g/mol*1/6.93g= 8.43moles of NaCL
1 mole of NH4NO3 requires absorption of 25.7 kJ/mol.
Therefore; 1 kJ of heat energy is absorbed by dissolving 1/25.7 moles of NH4NO3.
Hence; For an energy of 73.0 kJ to be absorbed the moles of NH4NO3 that dissolves will be;
= (1/25.7 × 73)
= 2.84 moles
Hence; 73 kJ is absorbed by dissolving 2.84 moles of NH4NO3.
You could solve it by analyzing the points by graphing them on a coordinate plane
Answer: 10 grams of Hydrogen gas will be produced theoretically.
Explanation: The equation for the reaction between zinc metal and hydrochloric acid is:
As HCl is present in excess, therefore limiting reagent is Zinc metal as it limits the formation of product.
By stoichiometry,
1 mole of Zinc metal produces 1 mole of Hydrogen gas, therefore
Amount of Hydrogen gas produced can be calculated by:
Molar mass of Hydrogen = 2 g/mol
Mass of hydrogen gas produced = (5 moles )× (2 g/mol)
Mass of hydrogen gas produced = 10 grams
