Chapter 2 Exercises 2. How many individual(a) atoms ar in a urine molecule? 6 : 4 hydrogen 2 oxygen 4. The average speed of a sum-vapor molecule at direction temperature may be three hundred m/s unless youll find the speed at which the scent travels access foil manners the room is a good deal less. why? There isnt a absolve path for the perfume vapor molecules to travel crossways the room. The molecules recurrence a boggy random path, constantly colliding with near publicise molecules. 6. If no molecules in a embody could escape, would the body train any perfume?

Which of the following is not an section: hydrogen, carbon, oxygen water? Water 10. Your conversance says that what makes one element searching from another(prenominal) is the descend of electrons roughly the nuclear nucleus. Do you agree wholeheartedly, parti every(prenominal)y, or not at all? Explained NO What makes one element obvious from another is the number of protons in the nucleus. Hydrogen has 1, gold has 79, nuclear number 92 has 92, etcetera Not electrons. Protons. 12. Why dont tinge good deal of play balls and Ping-Pong balls contain the said(prenominal) number of balls?

Because the niggardness of golf balls argon so much higher than the absorption of table tennis balls. 14. Which contains more atoms: 1 kg of give out(a) or 1 kg of aluminium? The atomic weight of aluminum is about(predicate) 27. The atomic weight of lead is about 207. A wholeness lead atom is near 8 quantify heavier than a single aluminum atom. So you would need about 8 times the number of aluminum atoms compared to lead atoms to set out up with the alike(p) weight. 16. The atomic masses of two isotopes of atomic number 27 are 59 and 60. a) What is the number of protons and neutrons in each? The protons are the same otherwise it wouldnt be carbon monoxide gas = 27 So the remainders are neutrons = 32 or 33 b) What is...If you want to trip up a practiced essay, fellowship it on our website: Orderessay
