Its a covalent bond for this q
Answer:
The molecules in the water become more separated due to heat.
Answer: 12 neutrons
Explanation: The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass). Sodium has a mass number of 23amu. Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.
Density = mass/volume
Since there was no condition of unit attached to the question...
Density = 100g/25.0ml
Density = 4g/mL.......
