3 If methane burns in a poor supply of air it will give carbon
rusak2 [61]

Answer:

2CH4 + 3O2 → 2CO + 4H2O

Explanation:

When methane is burnt in adequate supply of oxygen, then carbon dioxide is produced but when methane is burnt in limited supply of oxygen, then carbon mono-oxide is produced.

The balanced equation for the same is as follows -

2CH4 + 3O2 → 2CO + 4H2O

Consider four different samples: aqueous LiBr, molten LiBr, aqueous LiF, and molten LiF. Current run through each sample produce
Verizon [17]

Answer:

Following are the solution to the given question:

Explanation:

Please find the matching in attached file.

During the electrolysis of Molten LiBr : Li is reduced and Br are oxidized .

Lithium Metal is produced at the Cathod during the electrolysis of Molten LiBR .

In the aquous LiBr : In aquous LiBr potential of Li is greater than the of water then Li is reduced to produce solid Li ion.  As well As aqueous LiF ( electrolysis)and Molten LiF electrolysis produce the gas.  

aqueous LiF: Oxygen gas.

Molten LiF : Flourine gas.

Which of the following is a correct lewis structure for sulfur dioxide, so2?
pshichka [43]

The correct Lewis structure of SO2 is the Lewis structure that shows all the 12 valence electrons in the molecule.

A Lewis structure shows the number of valence electrons on the valence shell of all the atoms in a compound. The electrons are shown as dots around the symbol of each element or a dash to indicate shared electrons in a covalent bond.

Looking at the Lewis structure of SO2 attached to this answer, we can see the twelve valence electrons in the molecule and how they are distributed around each atom as shown.
