1) A - when iron oxidizes its chemical properties change. rather then the other answers because the other answers are physical change
3) D - table s shows that I- is has the largest radius.
5) D - in the periodic table the electronegativity increases going across and group 18 doesn't have a electronegativity leaving group 17 as the answer 
8) C - the answer is c because its symmertrical but it has is a polar bond because of its unequal sharing of electrons 
11) A - when you look at the table s and look at melting its 234k and so it will be the same going backwards
10)A- ideal gas law states gas particles go in a random straight line and no attractive force.
13)B- the messy room example showed how you use very little energy but at the end you get high entropy 
14) C- the answer is c because if you simply Aline the bright line spectra lines elements x and a are present in the mixture .
16) A- when a ion has a charge of negative 2 it suppose to mean the ion has 2 more electrons then protons.
18) B - according to Avogadro law volume = number of moles . so therefore gas sample 1 and 3 have a volume of 5 so both have 5 moles. 
19) A - in the table i if you look for the formula its 2NO2(g) and in the equation you have only 1 so therefore you divide by 2 66.4. and in the table its positive 66.4. therefore you get +33.2 
22)  C- the number in front the element is the atomic mass therefore you subtract the atomic number. and you get 2

13)the equation is specific change of heat. I got choice C by finding the difference of the temperatures and then I multiply the mass by waters specific heat capacity and then by the difference i got 9104.04 and moved  the decimal 3 place to the left to put in scientific notation and record the answer. ]]> 2019-04-08 20:54:07 UTC https://padlet.com/hanhbui/rxn3_1/wish/349713689 https://padlet.com/hanhbui/rxn3_1/wish/349741271 Answer is B the valence electrons are always found in the last outermost shell. ]]> 2019-04-08 23:44:36 UTC https://padlet.com/hanhbui/rxn3_1/wish/349741271 https://padlet.com/hanhbui/rxn3_1/wish/349742116 Answer is A because that’s the only answer that shows chemical formulas. ]]> 2019-04-08 23:48:08 UTC https://padlet.com/hanhbui/rxn3_1/wish/349742116 https://padlet.com/hanhbui/rxn3_1/wish/349742434 Answer is A because that is the only element there all the other ones are compounds. ]]> 2019-04-08 23:49:47 UTC https://padlet.com/hanhbui/rxn3_1/wish/349742434 https://padlet.com/hanhbui/rxn3_1/wish/349742830 Answer is A because as you increase the reaction rate you lower the activation energy. ]]> 2019-04-08 23:52:32 UTC https://padlet.com/hanhbui/rxn3_1/wish/349742830 https://padlet.com/hanhbui/rxn3_1/wish/349780357 10) i completed 
16) is choice D because Zn is above Ni on the table J activity series chart. Meaning that it’s more spontaneous than Ni. 
21) is Choice D because I’m order for the atom to be stable is must have the same number of protons and electrons. 
1) is choice A because heat got from hot to cold.
3) is choice B because H2O is a hydrogen bond which is the strongest intermolecular force.  ]]> 2019-04-09 03:17:58 UTC https://padlet.com/hanhbui/rxn3_1/wish/349780357 https://padlet.com/hanhbui/rxn3_1/wish/349938504 the answer choice is C because Xe is has the lowest density at those requirements.]]> 2019-04-09 13:59:59 UTC https://padlet.com/hanhbui/rxn3_1/wish/349938504 https://padlet.com/hanhbui/rxn3_1/wish/349939286 the answer choice is A because the electron configuration is 2-8-1]]> 2019-04-09 14:01:22 UTC https://padlet.com/hanhbui/rxn3_1/wish/349939286 https://padlet.com/hanhbui/rxn3_1/wish/349939722 the answer choice B because the definiton represents electronegativity]]> 2019-04-09 14:02:06 UTC https://padlet.com/hanhbui/rxn3_1/wish/349939722 https://padlet.com/hanhbui/rxn3_1/wish/349940443 the answer choice is B because the energy being absorbed represents a bond broken]]> 2019-04-09 14:03:25 UTC https://padlet.com/hanhbui/rxn3_1/wish/349940443 https://padlet.com/hanhbui/rxn3_1/wish/349941216 the answer choice is B because you need 2 moles so it can completely react]]> 2019-04-09 14:04:52 UTC https://padlet.com/hanhbui/rxn3_1/wish/349941216 https://padlet.com/hanhbui/rxn3_1/wish/349949662 17. A) Ammonia because it is a compound and compounds can be broken down by chemical means
25. D) 600. K and 50. kPa because this answer has the Highest temperature and lowest pressure 
20. D) Because NH3 has a lone pair which makes it asymmetrical 
2. C) 25g/225g X 100 because you have to divide mass of solute by the mass of solute + mass of solvent and multiply by 100
