Answer:
For H-Cl, the direction is towards the chlorine atom
For F-CH3, the direction is towards the flourine atom.
Explanation:
The dipole moment is a vector quantity. This implies that it has both magnitude and direction.
Thus, the direction of the dipole moment always points from the positive atom towards the negative atom.
This explains the fact that it points to chlorine in HCl and points to flourine in F-CH3
Answer:
Flowers play a crucial role in our lives; they have been used for generations to express the thoughts and feelings words cannot fully explain. Mother nature is the short term used to describe how nature gives life and nurture as a mother does for her children. As humans, we are part of mother nature's plan. We are also connected to plants and flowers, and some of the benefits have been passed to the next generation and will always be. We can control the air that we breathe, the aura around us, how we feel, and the things we attract in life. Other than only gifting your loved ones with flowers on special occasions, you can make the best and lasting impressions on your loved ones with a flower plant gift. This gesture shows that you understand how flowers are important in our life. To shed light on the importance of flowers in our life, here is a blog that will give five importance of flowers
Answer:
2 - Butyne
Explanation:
The name of the molecule with a carbon atoms arranged in a straight chain with a triple bond between the second and third carbons is 2 - Butyne.
2- Butyne is an alkyne with structural formula given below. Some of the properties of Butyne include it is a produced artificially, it is volatile and colorless in nature.
Hence, the given molecules described is 2 - Butyne.
Answer:
Heating this gas to 55 °C will raise its volume to 6.87 liters.
Assumption: this gas is ideal.
Explanation:
By Charles's Law, under constant pressure the volume 
of an ideal gas is proportional to its absolute temperature 
(the one in degrees Kelvins.)
Alternatively, consider the ideal gas law:
.
is the number of moles of particles in this gas. should be constant as long as the container does not leak.
is the ideal gas constant. 
is the pressure on the gas. The question states that the pressure on this gas is constant.
Therefore the volume of the gas is proportional to its absolute temperature.
Either way,
.
.
For the gas in this question:
- Initial volume:
.
Convert the two temperatures to degrees Kelvins:
- Initial temperature:
. - Final temperature:
.
Apply Charles's Law:
.
A Beta particles is emitted when an atom of 85Kr spontaneously decays.
