C16H32O2(aq) --> 16CO2(g) + 16H2O(l) ... said its wrong though? 
<span>This is because you haven't added any oxygen needed for the combustion, so your equation does'nt balance. Also a solution in water [aq] doesn't burn! </span>
<span>Try </span><span>C16H32O2(s) + 23O2(g) --> 16CO2(g) + 16H2O(l)

What is the oxidation number of Ni in NiO
galben [10]

Answer:

+2

Explanation:

Nickel (II) oxide, or NiO, is an ionic compound. Recalling a few rules of determining the oxidation number of substances:

1. Oxidation numbers of elements in ionic compounds are usually their own ionic charge

2. The total oxidation number of a neutral compound should be 0

And,

3. The oxidation number of oxygen in most cases is -2.

Therefore, since O in NiO has a oxidation number of -2, and nickel (II) ion usually has a charge of 2+, the oxidation number of Ni in NiO is +2 (always remember to put the positive sign in front of the number)

cricket20 [7]

Answer:

a) The pressure wiil be twice the original value

Explanation:

Pressure in inversely proportional to volume, that means; when one value decreases at the same rate that the other increases, if the temperature and amount of gas remain unchanged within a closed system. The above derived from the same definition of pressure.  The pressure is defined as the crashes and frequency of the same agains surface of objects, if certain amount of gas is  contained in a recipent, It will crash more times if the volume is minor. The Boyle´s law  express this mathematically.

P1V1= P2V2\\\\P2=\frac{P1V1}{V2} \\\\P2=\frac{P1*1L}{0.5L} \\\\P2=2P1\\\\\\where\\\\V1=  1L\\V2= 0.5L
