As you move from bottom on the periodic table to the top shielding
masha68 [24]

Answer:

AS we move from bottom to top on periodic table shielding decreased.

Explanation:

As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction.

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.

As we move from bottom to top the energy level decreased because of decreased in electron thus shielding decreased and atomic size also decreased.

2. The reaction of zinc with nitric acid was carried out in a calorimeter. This reaction caused the temperature
snow_lady [41]

We want to solve Q = mcΔT for the liquid water; its change in temperature will tell us the amount of thermal energy that flowed out of the reaction. The specific heat, c, of water is 4.184 J/g °C.

Q = (72.0 g)(4.184 J/g °C)(100 °C - 25 °C) = 22593.6 J

Q ≈ 2.26 × 10⁴ J or 22.6 kJ (three significant figures).

Which of the following is TRUE about an astronaut traveling from planet to planet?
DiKsa [7]

Answer:

The weight changes, but his or her mass does not.

Explanation:

The true statement from the given choices about an astronaut traveling from planet to planet is that the weight changes but his or her mass does not.

This is due to the difference in acceleration due gravity from one planet to the other.

  • Mass is the amount of matter present within a substance.
  • Weight is the vertical force on a body due to its mass and acceleration due gravity

Gravity from one planet to the other differs significant and so is the weight.
