Isomer is defined as compounds with the same formula but different arrangement of atoms in its molecule and they differ in their properties. The <span>representation that can be used to show differences between isomers is the use of structural formula. It shows the arrangement of each atoms. It cant be molecular formula and 3D drawing because it does not show the arrangement of the atoms.</span><span>

Answer: 37.8 grams
Explanation:-
As we know that
.................(1)
where,
q = heat absorbed or released
= mass of iron rod = 32.4 g
= mass of water = ?
= final temperature =
= temperature of iron rod =
= temperature of water =
= specific heat of iron rod =
= specific heat of water=
Now put all the given values in equation (1), we get
Therefore, the mass of the water is 37.8 grams
Explanation:
1. Under the influence of heat, wood produces easily substances that react eagerly with oxygen, leading to the high propensity of wood to ignite and burn.
2. Water is a natural conductor of electricity and if you throw water on an electrical fire, you can get shocked or electrocuted. Also, water may enable to fire to spread by conducting electricity throughout the room and potentially igniting flammable materials.
i may be wrong but i think its B. neutralization
