The answer is 6.02e24 molecules or 6.02x10^24 molecules.
The particles of the solute leave each other and become surrounded by particles of the solvent.
Answer:
Hydrogen Bonds Make Water Sticky
Explanation:
This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.
Answer:
d- 7.58 L
Explanation:
According to Charles's law, the temperature in Kelvin is proportional to the volume of a dry gas when the pressure is constant.
Mathematically, V1/T1 = V2/ T2
V1= initial volume= 6.6 L
T1= Initial temperature= 115 °C= (115 °C +273)=388K
V2= final volume
T2= final temperature= 173 °C= ( 173 °C+ 273)= 446K
Substitute the values,
V2=( V1 × T2)/ T1
= (6.6×446)/388
= 2943.6/388
= 7.6L
Explanation:
Which molecule does not obey the Octate rule of valence electrons .
BeCl2
FeCl2
CuCl2
ZnCl2
→BeCl2
Explaination:
BeCl2 violates the octet rule because the boron should be in a suitable valence state such that it binds to 3 chlorines. However, in this molecule boron is associated with six electrons.
