Answer:
K2CO3 and NaF
Explanation:
In order to ascertain which salt would form a basic solution we have to identify the classification of each of the salts.
- NH4Br: is the salt of a weak base (NH3) and a strong acid (HBr). This means that it would form an acidic solution.
- Pb(NO3): This is a normal salt, hence would not form a basic solution.
- K2CO3: This is salt that forms a strongly alkaline/basic solution.
- NaF: it is the salt of a strong base, NaOH, and a weak acid, HF. This means this would form a basic solution.
Answer: Some atoms of the same elements that have different atomic masses are called isotopes
Explanation:
so the atoms are the same element but different in mass. Since the isotopes have the same number of protons and electrons the isotopes have much the same chemical behavior. Since the isotopes have different numbers of neutrons the nuclear behavior differs.
The names of the compounds differ by the type of metal present in them, which are Calcium (Ca) and Cadmium (Cd)
From the question,
We are to determine the how the name of CaS differ from the name of CdS
First, we will determine the identities of the elements in the given compounds
Ca represents calcium
and
S represents sulfur
∴ The compound is named Calcium sulfide
Cd represents the element Cadmium
and
S represent the element Sulfur
∴ The compound is named Cadmium sulfide
Hence, the names of the compounds differ by the type of metal present in them, which are Calcium (Ca) and Cadmium (Cd)
