Answer:
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

Answer:
1.59 g/mL
Explanation:
Mass of CCl₄ = mass of flask and CCl₄ − mass of empty flask
m = 703.55 g − 345.8 g
m = 357.75 g
Density = mass / volume
d = 357.75 g / 225 mL
d = 1.59 g/mL
Answer:
Explanation:
An atom is constructed of three different particles known as electrons, protons and neutrons.
These particles have different mass and charges and are responsible for various characters than an atom posses.
An electron has a negative charge, a proton has positive charge and charge of neutron is neutral. Equal number of electrons and protons are present in an atom that make it electrically neutral but different conditions can occur if we remove these particles from an atom.
1 : Model of an ionized atom - an ionized atom is one which has some net charge on this. It can be either a positive charge or a negative charge.
If we need to sketch the model of an ionized atom then one should either keep the number of electrons less or proton.
2: Model of radioactive atom : A radioactive atom is one an unstable atom and has access of energy in its center. It can be caused by adding either neutrons or protons.
