Answer:
the correct answers is c
Explanation:
The electronegativity of bromine is 2.96 and that of potassium is less than 1, and its first ionization energy is 1139.9 kj / mol, while that of potassium is approximately 400.
Answer:
The answer to your question is:
Explanation:
1) Data
mass = 10 g
vol = 20 ml
density = 10/ 20
= 0.5 g/ml
2)
Data
mass = 5 g
density = 2 g/ml
volume = mass / density
= 5 g / 2
= 2.5 g / ml
3)
Data
density = 25 g/ml
volume = 100 ml
mass = 25 x 100
= 2500 g
