Answer:
Alkanes
Explanation:
The description of the first molecule corresponds to a cycloalkane. In the cycloalkanes for each carbon atom there are 2 hydrogen atoms (CnH2n = C5H10).
The second molecule corresponds to an open chain alkane, where for every carbon atom there is double plus 2 hydrogen atoms (CnH (2n + 2) = C5H12)
Answer:
2C2H6(g) + 7O2(g) ==> 4CO2(g) + 6H2O(g)
One way to find the limiting reactant is to divide the moles of reactant by the corresponding coefficient in the balanced equation and whichever is less is limiting.
For C2H6 we have 2 moles / 2 = 1
For O2 we have 8 moles / 7 = 1.14
Explanation:
If a reaction mixture contains 8 moles of O2(g) with 2 moles of C2H6(g),which reactant is the limiting reactqnt and what is the mass (in grams) remaining of the reactant in excess?
Answer:
A. The color change from blue to green happens in nature.
Explanation:
The color change is an indicator of a chemical reaction that has occurred. Although color changes are not necessarily good diagnostic tool to measure if a chemical reaction has occurred or not.
- In this reaction, color changes is quite an effective tool
- Chemical changes usually involves the formation of a new product from the chemical reaction.
- Also, the steps are not easily reversible.
- For this reaction, color change is the most appropriate signal for a chemical change.
N=9.933
Explanation:
no of mole = m÷mr
then ,no of molecules=n×la
The balanced chemical formula should be Al2(SO4)3 + 6NaOH = 2Al(OH)3 + 3Na2SO4
Therefore the coefficient of Al(OH)3 is 2!
Hope that helps :)
