<span>Compare Bromine and Krypton on the basis of their properties, attributes and periodic table facts. Compare elements on more than 90 properties. All the elements of similar categories show a lot of similarities and differences in their chemical, atomic, physical properties and uses. These similarities and dissimilarities should be known while we study periodic table elements. You can study the detailed comparison between Bromine vs Krypton with most reliable information about their properties, attributes, facts, uses etc.</span>
The answer is covalent bonding. Molecular compounds are made of 2 or more nonmetals, and are therefore covalent. That is why another name for "molecular compound" is "covalent compound".
Answer: (1) covalent bonding
Hope this helped!! :D
The density of the sample : 0.827 g/L
<h3>Further explanation</h3>
In general, the gas equation can be written
where
P = pressure, atm , N/m²
V = volume, liter
n = number of moles
R = gas constant = 0.082 l.atm / mol K (P= atm, v= liter),or 8,314 J/mol K (P=Pa or N/m2, v= m³)
T = temperature, Kelvin
n= 1 mol
MW Neon = 20,1797 g/mol
mass of Neon :
The density of the sample :
or We can use the ideal gas formula ta find density :

Answer:
The solution is 10^-2 or 0.01M in HCl.
Explanation:
meaning of pH is "power of hydrogen".
what is the molar concentration of a HCl solution with pH=2?
Let say pH=2
[H+]=10^-2M
HCL is a strong acid that dissociates completely:
[H+]=[HCL]
Therefore solution is 10^-2 or 0.01M in HCL.
