20. 4 because nh4 has uneven distribution so is asymmetrical
4. A because to melt, you multiply by 334j
19. B because 2 types of compounds are ionic or molecular
11. B because nucleus is the only positive atom, electron is negative
18. B because in H202, it has 2 additional oxygen atoms then h20
10. D because only electrons rotate around nucleus in their shells
24. B because nitrogen has bigger first ionization energy
16. D because 03 has one additional oxygen atom then o2, therefore is structured differently and properties are not same.
17. A because amnomia is a compound, N and H combined.
21. D because when bonds are broken, energy will release,but if bonds are together, energy will absorb in.
7. Because, cesium ion has lost valence electron so the atomic structure is smaller.
8. The charge distribution are both negative

First Diagonal
24. A is the formula for iron oxide
23) D. Two compounds switch
15) D Thermal energy because it has to do with heat
12)D because it absorbed energy and then it broke H^2 into H+H
21)A it provides lower activation energy

20. The answer is D because it is a double replacement
7. The answer is C because in table H of the reference table it shows that at 50 degrees Celsius the pressure of propanone is close to 83 kPa
4. The answer is D because carbon dioxide and carbon monoxide are 2 different compounds so their chemical and physical properties are different
1. The answer is A because when iron Oxidizes it is a chemical property
25. The answer is D because the elements can be differentiated based on malleability because iodine isn’t malleable but sodium is
9. The answer is A because the molecular polarity is what separates them
21. The answer is D because the ratio is 2:1 so to produce 2 moles of C2H6 you need 4 moles of C
3. The answer is D because in table S it shows that I has the largest radius out of all the choices
16. The answer is A because ion a has 8 protons and 10 electrons so 10-8=2 so it has a charge of 2-
24.  The answer is C because because it has one black dot and one white dot connected and there are other white dots
10. The answer is A because for an ideal gas it’s motion is a random straight-line and it ya no attractive force
2. The answer is B because diamond and graphite have different crystal structures
12. The answer is C because a chemical reaction occurs when reactant particles collide with proper energy and proper orientation

23) The answer is D because both NO3 and Cl are being swapped around
15) The answer is D because the water from the beaker is transferring heat into the ice cube
25) The answer is D
22) The answer is A because both granite and diamond have carbon in it, they have different crystal structures
8) The answer is B because copper is a metal and the other elements are all gases
17) The answer is A
9) The answer is A
24) The answer is A
14) The answer is A because carbon is an element, not a compound like the rest of the answers

3. B if temp decreases so does volume
4. D heat of fusion formula
5. C liquid to gas because a gas is much less stable than a liquid
7. Because there is more electrons connected the attraction is stronger in tighter in CsCI than in a a
10.D Wave mechanical model shows possible locations of electrons
12. B protons and Neutrons are the only particles that have mass in an atom
14.  A with every period from left to right Atomic number increases
15. A Te is an element right on the metalloid line, group 16 period 5

16.D they have different electron numbers therefore different properties like how Carbon is also diamond
19.B Empirical and Nuclear aren’t major compound categories. Process of Elimination
21. Someone told me the answer is C.
25.B ideal gas wants low pressure and high temps

2.Answer is B because graphite and diamond are allotropes, allotropes have different crystal structures.
4. Answer is D because they're both different compound so they're different physically and chemically.
8.Answer is A because CH4 is symmetrical base on its structure and its charge makes it nonpolar.
10.Answer is A because gas have no attraction and move in random,straight line motion.
11.Answer is A because when you go from liquid to solid, it is freezing and solid to liquid is melting.It makes sense to be able to melt because it's a reversible reaction. According to Table S,Hg have a melting point of 234 K.
14.Answer is C because only Element X and A matches the mixture.
15.Answer is D because each line in a spectra is created when released as electron go back to ground state.
19.Answer is A because it takes 66.4 kJ to make 2 moles of NO2,so inorder to make 1 mole,it'll take 33.2 kJ since everything is halved.

22.Answer is C because the 42 in   K-42 stand for proton plus neutron,in an atom, proton is always equal to the atomic number so K has 19 protons,42 minus 19 is 23 neutrons.
23.Answer is D because when an atom is excited one electron move from one shell to another, only D shows the change.
24.Answer is C because in a diagram of a mixture,there is no same combination of molecule, only C matches this description.
25.Answer is D because only way to differentiate sodium and iodine, is either malleability or conductivity, only D shows malleability of iodine and sodium.
