Plate tectonics are the broken plates of earth that move around and form the different plate boundaries
Answer:
STP in chemistry is the abbreviation for Standard Temperature and Pressure. STP most commonly is used when performing calculations on gases, such as gas density. The standard temperature is 273 K (0° Celsius or 32° Fahrenheit) and the standard pressure is 1 atm pressure.
The answer would be Linear. in Carbon Dioxide, the two double bonds count as two pairs of electrons around the carbon atom, predicting linear geometry.

Answer: difference in Vander Waals forces
Explanation:
The intermolecular force of attraction between the molecules in chlorine is WEAKER than that of Bromine.
This force is known as VANDER WAALS forces. And it DECREASES down the group; so Chlorine which is placed higher is a GAS, while Bromine placed lower in Group 7 is a LIQUID.
The correct answer is B. When temperature decreases the cold water is more dense due to molecules being stiffened together.
