Answer:
disagree
Explanation:
Cellulose (main component of wood beside lignin) is composed from carbon, hydrogen and oxygen with the following molecular formula (C₆H₁₀O₅)ₓ (where x is the degree of condensation of beta-glucose units which are the basic monosaccharide of the cellulose polysaccharide).
Now when you burn cellulose you obtain carbon (ashes), carbon dioxide (CO₂) and water (H₂O). Of course, beside the main products we may have other by-products but we consider them in very low quantity.
The difference between 3 kg of starting wood and 500 g of ashes is representing the quantity of carbon dioxide (CO₂) and water (H₂O) formed.
We have to say that CO₂ and H₂O are in gaseous state and escape in the atmosphere.
The law of conservation of mass is always valid.
Answer:
58.92 g EDTA
Explanation:
315.1 mL = .3151 L
M = Moles / Liter
.3151 L x <u>0.5 mol EDTA</u> x <u>374 g EDTA</u> = 58.92 g EDTA
1 L EDTA 1 mol EDTA
Because magnesium loses its electrons easily than aluminum
The combustion of methane, CH4, releases 890.4 kJ/mol. That is, when one mole of methane is burned, 890.4 kJ are given off to the surroundings. This means that the products have 890.4 kJ less than the reactants.
