#12: A because neutrons don't have mass
#19: B because ionic and molecular compounds are the highest possible category the other answers fall into these categories
#11: B because the protons in the nucleus make it positively charged
#6: Krypton has the closest configuration
#25: D because high temperature and low pressure are closest to ideal gas
#20: D because it's polar
#16: D because the definition of allotropes is different structures and properties and O2 and O3 are allotropes
#11: B because the protons in the nucleus make it positively charged
#7: cesium ion is smaller because cesium gives chloride an electron
#2: B because the equation to find your answer is mass of solute divided by the mass of solution times 100

     Option D is the only option that doesn't have a symmetrical structure. (doesn't have an equal number of H in NH3)
16_1c=D
      O2 and O3 have different molecular structures because O3 has one more molecule than O2. They also have different properties as O3 is deflects radiation. 
11_1c=B
     The nucleus has only a positive charge because it is composed of protons and neutrons. neutrons have no charge and protons have a positive charge.
7_1c
     When Cs bonds it looses electrons because it is a metal. This is why it is lager in its ground state than CsCl.
2_1c=D
Option D is the only that shows the KNO3 being removed from H2O.
23_1c=B
Both electronegativity and Nuclear aren't forms of energy. This fact means options A,C,D are false.

12) A - a electron and proton both has a mass of approximately 1 Au 
13) C- gold foil experiment found out that electrons are a subatomic particle 
16) D - o2 and o2 are allotropes so therefore have different structures and different properties 
19) A - ionic and molecular bonds are the major categories 
20 ) D- you draw all the answers and nh3 is the only one with a asymmetrical molecule 
21)  C - when bonds are broken energy must be absorbed in order to break the bonds and when bonds are formed energy must be released 
22) B- copper is the only bond so its a metallic bond 
25) D - a ideal gas has high temperature and low pressure and answer D has the highest temperature making it the most close to a ideal gas also low pressure.

2:  B the crystal structures changes to cause the graphite into diamond
10: A Ideally gasses have no attractive forces and constantly stay as a straight line 
12: C you would need enough energy and for the particles to hit very specifically for it to work
9: A It has nothing to do with boiling point, and electrical conductivity. There is also not a huge connection with malleability since its going though the paper]]> 2019-04-12 02:48:24 UTC https://padlet.com/hanhbui/rxn3_4/wish/351029328 Diego Sernadas 1c diego_sernadas https://padlet.com/hanhbui/rxn3_4/wish/351032461 21:  B it takes energy to form bonds and break them apart
13: D the other options don't match like the gold foil since it found that an atom has a nucleus
24: C it has the highest electronegativity  
14: C the elements are arranged by the atomic number
9: Ne-20 has 10 neutrons 
Ne- 22 has 12 neutrons]]> 2019-04-12 03:12:21 UTC https://padlet.com/hanhbui/rxn3_4/wish/351032461 Benito M Packet 1D https://padlet.com/hanhbui/rxn3_4/wish/351034316 17(B) Avagadro"s law is same volume then same amount of moles
4(B) Valence electrons are found in the outermost shell.
2(B)A positive Nucleus with electrons in the empty space
9(A) Table S says Ne has the lowest Density
5(A) Electrons are in orbitals.
7(A)The periodic table is arranged in increasing atomic number
22(A) Diamond and graphite are allotropes of carbon. They just have different crystal structures.
23(D) Double replacement because Cl and NO3 change places
1It is an open container so gas would leak out 
15(D)Thermal energy because heat is transferring to the ice cube
11(C)Adding the masses of atoms in a molecule it is finding formula mass
19(D)Temp has a role in chemical equilibrium 
16(D) Temperature is the average kinetic energy
