The answer to your question is: true.
Hope this helps!
4 moles of sodium because you originally have 2.0 moles of Na2SO4 and you set that up at the beginning of the (what we called) train tracks. Then diagonally from that, on the bottom you put 1 mol of Na2SO4 to cancel the units. Then above that you have 2 moles of sodium because that is how many there are in the equation that they gave (the Na2 part). Then its just like a fraction, you multiply the top by the top and the bottom by the bottom, which would give you 4moles/1 or just 4 moles Na. I hope that helps
Answer:
I₂ + H₂O --------→ HI + HIO
Explanation:
Iodine is not fully dissolve in water but only dissolve up to some extent.
When iodine was mixed with water it give mixture of two products.
- Hydrogen iodide or hydroiodic acid (HI)
- Hypoiodous acid (HIO)
So the balance reaction is as under
I₂ + H₂O --------→ HI + HIO
All the reactant are one mole and one one mole of each product produced in the shown reaction.
This is a reversible reaction and only 0.05% of Iodine molecule react with water and the other Iodine molecule remain in water unreacted.

<u>Answer:</u>
He should have put the glass in a broken glass bin
<u>Explanation:</u>
Putting broken glasses in the trash can or the dust bin can be hazardous to the workers working at local recycling center as the pieces might hurt them. Instead, he should have thrown the broken beaker in a separate glass bin or should have wrapped properly in paper so that it won't hurt anyone.
Also, glasses have a high melting point and therefore it is not recyclable. Hence, it should be trashed separately.
