Wave speed = frequency * wavelength
Wave speed = 1.80 * 0.30
Wave speed = 0.54 m/s
3) electronegativity difference
Explanation:
The degree of polarity of a bond is indicated by the electronegativity difference between the atoms that forms the bond.
Electronegativity is the of atoms in a bond to attract the valence electrons in chemical bond more closely to themselves.
- An atom with a high electronegative value often pulls the electron to itself more.
- If the elecronegativity difference between the two species is between 0.4 and 1.7, they are polar covalent bonds.
- If is is greater than 1.7, they are ionic bonds.
- If less than 0.4, then a non-polar covalent bond must have formed.

The temperature : 332.75 K
<h3>Further explanation</h3>
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
volume of gas = 790 cm³ = 0.79 L
mol of gas at STP :
Use ideal gas :
P=726 mmHg=0.955 atm
V= 1000 cm³ = 1 L
Answer:
When an object moves, we often refer to the amount it moves as the distance. Distance does not need a reference point and does not need a direction. If an automobile moves 50 kilometers, the distance traveled is 50 kilometers regardless of the starting point or the direction of movement.
Answer : If an increase in temperature accompanies a reaction, energy is released. Explanation :In thermodynamics, the reaction is considered as a system and the medium in which the reaction occurs which is usually an aqueous medium is considered as its surrounding. When the heat flows from the system to its surrounding, it increases the temperature of surrounding medium because the heat released by the system is absorbed by its surrounding. This is known as exothermic reaction. An exothermic reaction is always accompanied by energy release. On the other hand, when the heat flows from the surrounding towards system, it decreases the temperature of the surrounding medium. This is known as endothermic reaction. From the above discussion we can say that If an increase in temperature accompanies a reaction, energy is released.
Good luck ;)
