The study of atomic structure helps us understand more about the way the universe is constructed, how our bodies are made, and the components of life, which we can apply to other sciences in the fields of: health and disease prevention, fuels, product industry etc... It basically helps us to understand how we can make new things and how to utilize the power of the universe.
Answer:
73.97 kPa
Explanation:
It's helpful to know the conversion factors and apply them.
First, convert from torr to atm:
555 torr ÷ 760 atm = 0.730 atm
Next, convert from atm to Pa:
0.730 atm × 101,325 Pa = 73967 Pa
Finally, convert to kPa (1000 Pa in 1 kPa):
73967 Pa ÷ 1000 kPa = 73.97 kPa
Answer:
The first option
Explanation:
because the liquids have different densities, oil is less dense so it floats to the top once it does its easy to separate them due to the separation.
Answer:
Stretching and bending vibrational modes are affected
Explanation:
Frequency region for IR (infra red) radiation is 4000-400 
Stretching and bending frequencies of covalent bonds in a molecule lies within range of IR radiation.
When a molecule is excited with IR radiation, frequencies related to stretching and bending mode of covalent bond resonates with incoming frequency of radiation by obeying some certain quantum mechanical selection rule.Therefore we can identify those stretching/bending mode and thereby identify a particular covalent bond.
So, option (C) and (D) are correct
