Answer:
3.45 x 10^24 x 1 / 6.022 x 10^23 = 573
A. Raccoons. They will be able to survive in a housing area just as well, or even better then they had in the forrest.
I hope that helped! :D
Thomson's model of the atom was called the plum pudding model. He discovered electrons, so he placed them in the atoms. This was before the nucleus was discovered.
Now, the current model is an atom that contains a positively charged nucleus (with both protons and neutrons), and negatively charged orbitals with electrons.
Answer:
Density is 6.16g/L
Explanation:
<em>... at exactly -15°C and exactly 1atm...</em>
<em />
Using general gas law:
PV = nRT
We can find density (Ratio of mass and volume) in an ideal gas as follows:
P/RT = n/V
<em>To convert moles to grams we need to multiply the moles with Molar Weight, MW:</em>
n*MW = m
n = m/MW
P/RT = m/V*MW
P*MW/RT = m/V
<em>Where P is pressure: 1atm;</em>
<em>MW of chlorine pentafluoride: 130.445g/mol</em>
<em>R is gas constant: 0.082atmL/molK</em>
<em>And T is absolute temperature: -15°C+273.15 = 258.15K</em>
<em />
Replacing:
P*MW/RT = m/V
1atm*130.445g/mol / 0.082atmL/molK*258.15K = m/V
6.16g/L = m/V
<h3>Density of the gas is 6.16g/L</h3>

Answer:
My role models are my parents. They are my pillars of strength. They are my guide and give me the courage to battle obstacles in life.
My mother, being a working professional, manages all her work perfectly and with efficiency.
My father goes to office, but still does not forget to help me with my studies. They always encourage me in every aspect and motivate me even when I do not succeed.
My mother always smiles, no matter what the circumstances are and that gives me the strength and inspiration to face all problems.
My parents have made me understand what life is about and how to find that little ray of happiness in difficult situations.
What I am today and what I will become in future involves the support and affection of my parents. They have made me disciplined, dedicated and sincere.
A role model does not have to be a famous personality. It can be anyone who makes us believe in ourselves.
My parents fill sweetness in my life. From childhood I have learnt everything from my parents.
Not just parents, I also consider my teachers as role models. Even they guide me and show the path of success.
They have turned me into a fighter in the war of life
