Answer:
2Na + Cl2 ------> 2NaCl
4H2O2 --------> 4H2O + 2O2
CH4 + 2O2 -------> CO2 + 2H2O
Explanation:
An Element, hope i helped out
Used mainly in the context of Geography a Constructive force is involved in making new land while a Destructive force breaks the land. As they are carrying opposite functions to one another they are considered as competing forces.
The typical bond angles (in degrees) in molecules with 4 electron groups will be <u>109.5 degrees</u>.
The angle that exists among two covalent bonds that come from the same atom is known as a bond angle.
When there have four bonds and no lone pairs, the tetrahedral geometry occurs. Given that many molecules would adopt this geometry, it represents one of the most significant and prevalent geometries. For example, assumes a tetrahedral geometry. Tetrahedral molecules have a bond angle of around 109.5°.
Therefore, The typical bond angles (in degrees) in molecules with 4 electron groups will be <u>109.5 degrees</u>.

(1) • Balanced Equation : 2HgO (s) ---> 2 Hg (l) + O₂ (g)
• Line a is represented by activation energy, or the smallest amount of energy needed for molecules to undergo a chemical reaction.
• Activated complex is the intermediate state during the conversion of reactants into products. In this case it is represented by Hg----O-----O----Hg. The dashed lines indicate that the bond between Hg and O are breaking and their length is increasing and the dashed line between oxygen atoms indicate that the bond is decreasing and bond formation is taking place.
• This reaction is endothermic as the energy of reactants is smaller than the energy of products.
(2) • Balanced Equation : CH₃Br + OH⁻ ---> CH₃OH + Br⁻
• The hydroxide ion reacts with the bromomethane, resulting in a double replacement reaction. The 'CH₃' in 'CH₃Br' joins with the hydroxide ion to form CH₃OH, while the Br breaks off as an ion.
• Take a look at the energy diagram below.
