Answer:
Below.
Explanation:
Because of the hydrogen bonding that occurs in water. Oxygen is more electronegative than sulphur and forms inter molecular bonding between the H+ and O- ions in the water. This does not occur in H2S.
Answer:
2NH4NO3->2N2+O2+4H2O

U have to ensure that they are equal both side s hope it helps
Answer:
Water vapor retains the same heat energy.
Given:
Ksp (CaF2) at 25 degrees Celsius = 3.9 x10^-11
volume of CaCl2 = 100 ml
concentration of CaCl2 = 2.3 x 10^-4 m
Volume of NaF = 500 ml
concentration of NaF = 5.0x10^-3 m
Total volume = 100 + 500 = 600 ml
balanced chemical equation:
2NaF + CaCl2 ===> CaF2 + 2NaCl
calculate the number of moles NaF and CaCl2. Then determine the resulting moles of CaF2 (based on the limiting reactant) and find the concentration of CaF2. If it is more than the Ksp, meaning there will be a precipitate.
Answer:
Covalent bonds
Explanation:
The type of bond present in methane is covalent bonds.
In covalent bonds, two species share electrons to give an interatomic interaction.
The two species are always non-metals with little to no electronegativity differences between the two of them.
Carbon is made of 4 valence electrons. It will require an additional 4 electrons to attain stability
Hydrogen has one electron its outer shell. When each of the four hydrogen shares their single electrons with carbon, the central carbon will attain an octet configuration. The binding hydrogen will have a complete orbital too.
