Answer:
The law of conservation of mass states that matter can not be created or destroyed in a chemical reaction.
Explanation:
The correct is D.
Water is a polar molecule and it has polar bonds, which carry partially positive and partially negative charges. This polar bond increases the attraction between molecules of water and thus it requires a greater energy to break the bond between the molecules of water compare to carbon dioxide, which is a non polar molecule. Thus, water has a higher boiling point than carbon dioxide.
Answer:
0.3808
Explanation:
number of moles,n=Conc.XVol.
hence 0.85X0.448
Answer:
Second option - The bond is very polar
Explanation:
Electronegativity of an basically refers to the degree at which an electron is able to attract electrons to itself.
There are different types of bonds between atoms, depending on the electronegativity of the atoms.
When there is a large difference in electronegativity, it pretty much means that one atom would draw electrons more than the other. When this happens, the bond is said to be polar because there is uneven distribution of the charges.
The second option is the correct answer in thus question.
Answer:
This is not a balanced equation
Explanation:
Let's make it a balanced equation.
2 NH3 + H2So4 = (NH4)2So4
