Explanation: Electron dot structures are the lewis dot structures which represent the number of valence electrons around an atom in a molecule.
The electronic configuration of potassium is ![[Ar]4s^1](https://tex.z-dn.net/?f=%5BAr%5D4s%5E1)
Valence electrons of potassium are 1.
The electronic configuration of Bromine is ![[Ar]4s^24p^5](https://tex.z-dn.net/?f=%5BAr%5D4s%5E24p%5E5)
Valence electrons of bromine are 7.
These two elements form ionic compound.
Ionic compound is defined as the compound which is formed from the complete transfer of electrons from one element to another element.
Here, one electron is released by potassium which is accepted by bromine element. In this process, Potassium becomes cation having +1 charge and Bromine become anion having (-1) charge.
The ionic equation follows:

The electron dot structure is provided in the image below.
Answer:
all these are physical properties except release of heat so it's probably heat energy given off
Newton's first law of motion is the law of inertia. There are basically "two parts" to the law of inertia. The first part says that an object at rest tends to remain at rest unless it is acted on by an outside force. Think of gravity.

Answer:
n= 2.55 moles
Explanation:
Using the formula of ideal gas law:
PV = nRT
nRT=PV
n= PV/RT
n= number of moles
R= Avogadro constant = 0.0821
T= Temperature in K => ºC + 273.15 K
V= volume in L
P= pressure in atm
n= (1 atm)(57.20 L) / (0.0821)(237.15 K)
n= 2.50 moles
Answer:
the answer would be volume. (D)
Explanation:
it is not length, mass, or temperature.
