Answer:
NaI
Explanation:
Sodium has a charge of 1+ and iodine has a charge of 1-. They exist in a one-to-one ratio. Because they are ionic compounds, they go for the lowest ratio available.
Answer:Number of proton present in the nucleus of an atom of sulfur is 16.
Explanation:
Protons, neutrons and electrons are subatomic particles of an atom.
Atomic number of an atom is equal to the total number of protons present in the nucleus of an atom.
Z = total number of protons
Atomic mass of an atom is defined as sum of the number of protons and neutrons present in the nucleus of an atom.
In neutral atom there are equal number of protons and electron.
A = number of proton + number of neutrons
According to question, there are 16 electrons in neutral atom of Sulfur.
in a neutral atom:
Number of electrons = Number of protons = 16
Number of proton present in the nucleus of an atom of sulfur is 16.
Answer:
17.5 g
Explanation:
Given data
- Mass of solution to be prepared: 50.0 grams
- Concentration of the salt solution: 35.0%
The concentration by mass of NaCl in the solution is 35.0%, that is, there are 35.0 grams of sodium chloride per 100 grams of solution. We will use this ratio to find the mass of sodium chloride required to prepare 50.0 grams of a 35.0% salt solution.
