Expected to deal with what? Fires?
Answer:Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.
Explanation:
The best way (in my opinion) is to put it in a table or spreadsheet.
Answer:
Lewis structure in the attached image.
Explanation:
To draw the Lewis structure of H₂SO₄, we need to consider the octet rule: atoms gain, lose or share electrons to have 8 electrons in their valence shell. Hydrogen is an exception because its valence shell is complete with 2 electrons (duet). H, S and O are nonmetals, so they form covalent bonds to complete their valence shell, that is, they share pairs of electrons.
- S has 6 valence electrons, so it has to share 2 pairs of electrons to reach the octet.
- O has 6 valence electrons, so it has to share 2 pairs of electrons to reach the octet.
- H has 1 valence electron, so it has to share 1 pair of electrons to reach the duet.
In the attached image is the resulting Lewis structure.
