Answer:
37.5 g NaCl
Explanation:
Step 1: Given data
- Concentration of NaCl: 15.0% m/m
- Mass of the solution: 250.0 g
Step 2: Calculate how many grams of NaCl are in 250.0 g of solution
The concentration of NaCl is 15.0% by mass, that is, there are 15.0 g of NaCl every 100 g of solution.
250.0 g Solution × 15.0 g NaCl/100 g Solution = 37.5 g NaCl
Answer:
Asexual reproduction
Explanation:
Cells are able to re produce themselves without other cells needed. If cells need others to make more then how would that work and plus we wouldn't have the theory of cells existing.
Answer:
sp3d
Explanation:
The ground state electronic configuration of tin is; [Kr] 5s²4d¹⁰5p². Hybridization is a valence bond concept that postulates that orbitals of appropriate energy could be mixed in order to produce suitable orbitals that could be used for bonding.
In the formation of Snf5^ -1, there is a hybridization of the 5p, 5d and 6s orbitals to yield the sp3d orbitals required for the formation of the chemical specie hence the answer.
