Answer:
H2 is Molecular hydrogen. It is a molecule of hydrogen that consists of two hydrogen atoms bonded together by one single bond
Explanation:
Answer: 0.635 M
Explanation:
Molarity : It is defined as the number of moles of solute present per liter of the solution.
Formula used :

where,
n= Moles=
= volume of solution = 150 ml


as 1 mole of
gives 3 moles of
ions
Thus molarity of
= 
Molarity of
= 0.635 M
Answer:
Partial pressure of Ar = 4.7 atm
Explanation:
Total pressure of a mixture of gases = Sum of partial pressure of each gas
This mixture contains: O₂, He and Ar.
Total pressure = 15.3 atm
Total pressure = Partial pressure O₂ + Partial pressure of He + Partial pressure of Ar
15.3 atm = 7.4 atm + 3.2 atm + Partial pressure of Ar
Partial pressure of Ar = 15.3 atm - 7.4 atm - 3.2 atm
Partial pressure of Ar = 4.7 atm
Answer:
Neutral (no net charge)
Explanation:
Protons - Positive
Electrons - Negative
Neutrons - No charge
<em>Why? </em>
Neutrons are the particle in an atom with a (as the name suggests) neutral charge. They are neither positive nor negative, unlike protons or electrons.
Answer:
Frying an egg is a chemical reaction. It is an example of an endothermic reaction, or one that takes in heat in order to make the reaction occur.
