I believe body waves can actually reach the core as they follow raypaths refracted by the varying density and modulus of Earths interior.
Hope this helps!
The mass of zinc required to react with HNO3 is 3.45 g
<h3>What is moles of HNO3 reacting?</h3>
The moles of HNO3 reacting is calculated using the formula below:
- moles = concentration × volume
volume = 0.850
volume = 125.0 mL = 0.125 L
Moles of HNO3 = 0.850 × 0.125 = 0.10625 moles
Equation of reaction:
Zn + 2 HNO3 --> Zn(NO3)2 + H2
2 moles of HNO3 reacts with 1 mole of Zn.
moles of zinc reacting = 0.10625/2 = 0.053125
Mass of zinc = moles × molar mass
molar mass of Zn = 65
Mass of zinc = 0.053125 × 65
mass of Zn = 3.45 g
Therefore, the mass of zinc will completely react with 125.0 mL of a solution of nitric acid (HNO3) which has concentration of 0.850M is 3.45 g

Hello there!
Electronegativity is the atom's tendency to attract electrons in a chemical bond
There are two trends to electronegativity:
- Electronegativity increases from bottom to top in a group (Li has a greater electronegativity than Fr, for example)
- Electronegativity increases from left to right across a period (the further right the group, the greater the electronegativity)
Looking at a period table, Sb, Sn, Te, and I are all in the same period, so we'll need to decide which element has the highest electronegativity based on the group.
- Sn belongs to group 4A (group 14)
- Sb belongs to group 5A (group 15)
- Te belongs to group 6A (group 16)
- I belongs to group 7A (group 17)
As I belongs to group 7A, the group that is the farthest right based off of the options given, I has the highest electronegativity

Overall, it depends on your opinion. Some people think roses are prettier than daisies, and daisies are prettier than roses.
Roses are the definitive symbol for love and appreciation, while daisies are a symbol of Virgin Mary representing her chastity, grace, and purity. Daisies represent beauty and patience as well.
