1. Reaction calculations a. The combination of hydrochloric acid and sodium hydroxide to make sodium
chloride and water.
i. Write a balanced chemical equation for the process. Be sure to include
states of matter.
If you start with 24.0 mL of 2.00 M sodium hydroxide, how many moles
of hydrochloric acid do you need?

The difference between the atomic number of an element and the element’s atomic mass is the number of ions.

The number of neutrons is equal to the atomic number minus the atomic mass. a. true b. false

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
