Answer:
Explanation:
Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon
dioxide as shown below.
CaCO3(s) = CaO(s) + CO2(g)
The Kp for this reaction is 1.16 at 800°C. A 5.00 L vessel containing 10.0 g of CaCO3(s)
was evacuated to remove the air, sealed, and then heated to 800°C. Ignoring the volume
occupied by the solid, what will overall mass percent of carbon in the solid once equilibrium is reached?
Answer:
A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is: AB→A+B. Most decomposition reactions require an input of energy in the form of heat, light, or electricity.
Explanation:
Hopefully this helps :)
The balanced equation is C6H14(g)
+ 19/2O2(g) → 6CO2(g) + 7H2O(g). If you are given 7.9 moles C6H14, multiply it
by a ratio of 19/2/1 to get the moles of oxygen. Then, you will get 75.05 moles
of O2.
#2 It gives out more energy :)
Answer:
2 or more
Explanation:
There are 2 or more valid electron dot formulas—having the same number of electron pairs for a molecule or ion—can be written when a resonance structure occur as we know that Sharing of electrons takes place so that atoms achieve noble gas configurations. So, How is it that an electron dot arrangement reflects a covalent bond? An electron dot arrangement represents a pair of dots with the mutual electrons of a covalent bond. A great energy of dissociation from bonds leads to a solid covalent bond.
