Answer:
821.25gm
Explanation:
volume = 657
no of mole = 657/22.4
mass = no of mole * molecular mass
mass = 657/22.4*28
= 821.25gm
Answer:
0.404 mol / L
Explanation:
The <em>total moles of barium chloride</em> can be calculated from <em>the volume and concentration of the stock solution</em>:
1.39 mol/L * 0.180 L = 0.2502 moles barium chloride
Now we <u>calculate the concentration of the working solution, by dividing the total moles by the final volume</u>:
0.2502 mol / 0.620 L = 0.404 mol / L
Answer:
1. 24.7g of Br2
2. 19.9g of HCl
Explanation:Please see attachment for explanation
Answer:
The statement "The total mass of hydrochloric acid and sodium hydroxide will result in the same total mass of sodium chloride and water." is true due to the Law of Conservation of Mass which states that matter cannot be created nor destroyed.

Explanation:
Resonance is a valence bond terminology which is used to describe a situation in which a single structure is not able to fully describe the nature of bonding in a molecule.
In such cases, we invoke more than one structure. Each structure contributes significantly to our understanding of the nature of bonding in the molecule under consideration and these structures are called canonical or resonance structures.
The real structure of the molecule is somewhere in between these structures - a resonance hybrid.
For ozone, two equivalent structures can be used to describe the bonding in the molecule. These structures are equivalent as shown in the mage attached. We can see from these structures that the bond order in ozone is 1.5(one and half bonds)
