Answer:
Evaporated via combustion.
Explanation:
The loss on ignition (LOI) and Ash content are inorganic analytical techniques used to determine the percentage by mass of hydrocarbon in compounds. This process allows volatile matter and possibly impurities found in a material to evaporate, leaving behind the true chemical constituents of the material.
The 10kg lost could be moisture content of the tree, or other volatile matter which has escaped on combustion of the tree.
The mass percent of oxygen in Nickel(
)sulfate is 
percent.
At first, we look up the atomic masses for the element from the periodic table.
The atomic masses are found to be:
Next, we determine how many grams of each element are present in one mole of 
The mass of one mole is:
So, The mass percent of oxygen 
percent.

If 6 units of AB were reacted with 10 units of CD in the described equation, the limiting reactant would AB
<h3>Limiting reactants</h3>
They are reactants that determine how far a reaction can go in terms of yield.
From the equation: 3AB + 4CD --> 2AD + 6CB
The mole ratio of AB to CD is 3:4
Thus, 6 units of AB will require 8 units of CD.
But 10 units of CD were reacted with only 6 units of AB. This means that CD is in excess by 2 units while AB will limit the yield of the reaction.

Answer:
403 mL
Explanation:
First, I will assume that the mole is 1, because you are not specifing this.
Now, with the innitial data, we need to get the pressure:
T = 65+273 = 338 K
V = 500 / 1000 = 0.5 L
Now if:
PV = nRT
Then:
P = nRT/V and V = nRT/P
Let's calculate the P:
P = 1 * 0.082 * 338 / 0.5 = 55.432 atm
The standard temperature is 0° C or 273 K so, the volume is:
V = 1 * 0.082 * 273 / 55.432
V = 0.40384 L or simply 403.84 mL
