Atomic number is the number of protons in an atom. Since these are all Hydrogen, the number of protons remains the same, and the Atomic Number for each is 1. Mass number is the number of Protons and Neutrons in an atom. So, Protium is 1, Deuterium is 2, Tritium is 3. The number of neutrons is stated in the question (Protium 0, Deuterium 1, Tritium 2). Hope this helps, if you wouldn’t mind marking brandies if it did!
The value for ΔG = 18 kJ/mol
<h3>Further explanation</h3>
Given
ΔH = 27 kJ/mol and ΔS = 0.09 kJ/mol.K
T = 100 K
Required
the value for ΔG
Solution
The spontaneous process of a reaction is based on 2 factors :
- enthalpy change ΔH decreases and
- entropy change ΔS increases
ΔG=ΔH-T.ΔS
Answer:
Bromine pentafluoride, BrF5
bromine pentafluoride is an interhalogen compound and a fluoride of bromine. It is a strong fluorination reagent. BrF5 finds use in oxygen isotope analysis.
Answer:
A. Molarity will increase .
Explanation:
Molarity = moles of solute per litre of solution
= moles of solute / volume of solution
If evaporation occurs , volume of solution decreases and moles of solute remains constant . Hence denominator decreases and numerator remains constant .
Hence the molarity increases .
Answer:
.125 M
Explanation:
.15 M/L * .125 L = .01875 moles
now dilute to 150 cc (by adding 25 cc)
.01875M / (150/1000) = .125M
