Metals are solids, non metals are gasses and metalloids are in between metals and non metals. Also, metals have there atoms all close and packed, non metals have there atoms far apart, and metalloids have there atoms either close or far apart. Metals are separated form the non metals in the periodic table.

erastovalidia [21]

Answer: The energy of a mole of photon associated with this frequency is 49.5\times 10^{-20}J

Explanation:

The energy and frequency are related by :

E=N\times h\times \nu

E = energy of photon

N = number of moles = 1

h = planks constant = 6.6\times 10^{-34}Js

\nu = frequency = 7.5\times 10^{14}Hz

E=1\times 6.6\times 10^{-34}Js\times 7.5\times 10^{14}s^{-1}=49.5\times 10^{-20}J

The energy of a mole of photon associated with this frequency is 49.5\times 10^{-20}J

How many moles of co2 are found in a 168.2 gram sample
andrew11 [14]

Answer:

Number of moles = 3.82 mol

Explanation:

Given data:

Number of moles of CO₂ = ?

Mass of CO₂ = 168.2 g

Solution:

Number of moles = mass/molar mass

Molar mass of CO₂ = 44 g/mol

By putting values,

Number of moles = 168.2 g/ 44 g/mol

Number of moles = 3.82 mol

What are 3 general rules to predict the stability of an isotope
Mashcka [7]
<span><span>1) Calculate the total number of nucleons (protons and neutrons) in the nuclide
<span>--> If the number of nucleons is even, there is a good chance it is stable.
</span></span><span><span>
2) Are there a magic number of protons or neutrons?
</span>--> 2,8,20,28,50,82,114 (protons), 126 (neutrons), 184 (neutrons) are particularly stable in nuclei.
</span><span>
3) Calculate the N/Z ratio.
<span>--> Use the belt of stability (Figure 1) to determine the best way to get from an unstable nucleus to a stable nucleus</span></span></span>
