Gravity pulls mass towards its center, therefore as matter is pulled towards a source of gravity it will naturally coalesce into a ball as matter competes to head towards the source of gravity.
The electrical charge of an atom having 15 proton, 14 neutrons and 16 electrons is -1. The correct option is D.
What is an atom?
An atom is the smallest unit of any matter which comprises of central nucleus and electrons revolving around the nucleus in definite energy shells. The atom is made up of protons, neutrons and electrons.
The electrical charge of an atom can be calculated as,
Charge of an atom = number of protons - number of electrons
Charge = 15 - 16 = -1.
The neutrons are neutral and do not contribute to the charge, the protons are positively charged and electrons are negatively charged in an atom.
Therefore, the charge of an atom with 15 protons, 14 neutrons and 16 electrons is -1. The correct answer is option D.

Answer:
Explanation:
Carbon dioxide is the answer I think.
Hope it helps...
gas = methane
burn with O₂ (oxygen)
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l)
Answer: That would be false because it is the contact between two layers representing a gap in the geologic record, usually from the erosion of the layers which would normally be expected to appear.
