It has to be D. the time needed to boil the water decreased
The enthalpy of combustion of propane is -2202.0 kJ/mol.
The enthalpy of combustion is released when one mole of compound is burned in the presence of excess oxygen. The bonds between carbon and hydrogen in the compound are broken and bonds between carbon and oxygen are formed as well as bonds between hydrogen and oxygen are formed.
Hello!
The coefficient for Lithium Acetate in the balanced chemical equation is 6
Why?
This is the reaction:
(CH₃COO)₂Ca(aq) + Li₃PO₄(aq) → Ca₃(PO₄)₂(s) + CH₃COOLi(aq)
For balancing the equation, we're going to apply the Law of Conservation of Mass, which states that matter is not created nor destroyed, and the number of atoms of each element should be the same on both sides of the equation, from that, the balanced equation is:
3(CH₃COO)₂Ca(aq) + 2Li₃PO₄(aq) → Ca₃(PO₄)₂(s) + 6CH₃COOLi(aq)
Have a nice day!
Answer:
A)Chlorine and Bromine:
They are both non metal hence they form a covalent bond due to covalent bonding.
B)Potassium and Helium:
Helium ion has a small cationic radius and distorted by the potassium ion due to polarization.
C)Sodium and Lithium:
Both are metals hence they form a metallic bond since they share electrons to the electron cloud.
Answer:
No pain, no gain is a proverb that means in order to make progress or to be successful, one must suffer. This suffering may be in a physical or mental sense. The phrase no pain, no gain was popularized in the 1980s by the American actress, Jane Fonda.
