Based on atomic mass
Explanation:
Elements were arranged on the first periodic table based on their atomic masses.
The mass of an atom is made up of the mass of the nucleus which contains the protons and neutrons.
- Dimitri Mendeleev was the first person credited for arranging elements periodically.
- He was said to have been inspired while playing his game of solitaire on a train.
- On his table, he left spaces for the atomic masses of elements not yet discovered.
- Today, the periodic table is based on the atomic numbers of elements. This is the number of protons in an atom.

The hurricane is located off the coast of Florida to the right. The center of the hurricane will have high pressure and it will be much more compared to the pressure in Tampa bay. This is because of the distance of the isobars, the closer the isobars are together the higher the pressure
Answer:
Distance lift the tree = 0.5 m
Explanation:
Given:
Work done = 50 joules
Force = 100 newton
Find:
Distance lift the tree
Computation:
Distance = Work done / Force
Distance = 50 / 100
Distance = 0.5 m
Distance lift the tree = 0.5 m
Hey there!:
moles of NaOH = 10.1 / 40 = 0.2525
heat = ΔH x moles
= 44.4 x 0.2525
= 11.21 kJ
total mass = 10.1 + 250 = 260.1 g
Q = m Cp dT
11211 = 260.1 x 4.18 x dT
dT = 10.3
T2 = 10.3 + 23 = 33.3 °C
temperature = 33.3 ºC°
Hope this helps!
