Answer:
When atom loses a electron
Answer:
Ca(OH)₂ and HCl(aq)
Explanation:
We have the products of a reaction, CaCl₂ and H₂O. Since the products are a salt and water, this is likely to be a neutralization reaction. In such a reaction, an acid and a base react to form a salt and water.
- The acid provides the anion of the salt. Since the anion is Cl⁻, the acid is HCl(aq).
- The base provides the cation of the salt. Since the cation is Ca²⁺, the base is Ca(OH)₂(aq).
The complete molecular equation is:
Ca(OH)₂ + 2 HCl(aq) → CaCl₂ + 2 H₂O
Answer:
For each of the salts on the left, match the salts on the right that can be compared directly, using Ksp values, to estimate solubilities. (If more than one salt on the right can be directly compared, include all the relevant salts by writing your answer as a string of characters without punctuation, e.g, ABC.) fill in the blank 1 1. manganese(II) sulfide A. CuS fill in the blank 2 2. calcium fluoride B. FeS C. PbCl2 D. CaCrO4 Write the expression for K in terms of the solubility, s, for each salt, when dissolved in water. manganese(II) sulfide calcium fluoride Ksp
Answer:
Atomic emission spectra are produced when excited electrons return to the ground state. The emitted light of electrons corresponds to energies of the specific electrons.
