Answer:
- <em>Stored chemical energy is converted to mechanical energy.</em>
Explanation:
A <em>battery</em> posses <em>chemical energy</em>: this is chemical potential energy, which means that it is stored in the chemical bonds of the compounds in the battery. When the compounds in the battery react some bonds are broken and others are formed; at the end some energy is released and electricity is produced.
So, the chemical energy is first transformed into electrical energy.
A motor in the toy is able to transform that electrical energy into motion of gears and axes, which is how the wheels can spin. This motion of gears, axes and wheels is mechanical energy (kinetic energy).
Then, as you see, in that way the stored chemical energy in the battery is transfered to mechanical energy of the toy as it <em>rolls across the floor</em> thanks to the spin of the wheels.
Hydrogen has only 2 electrons, so it can't lose 5 electrons!!!
The type of structural isomerism arises when a particular ligand is capable of coordinating to a metal in two ways is linkage isomer.
<h3>What are structural isomerism?</h3>
Structural isomerism is a kind of isomerism in which molecular formula of the compound is same but they all have different arrangement of atoms or bonding in them.
If in any compound particular ligand is attached to the metal through different sides of the compound, then the product which is formed by these arrangement is known as linkage isomers.
Example of the linkage isomer is attached below.
Hence, the required isomerism is linkage isomerism.

Explanation:
AH is negative because the reaction gives out heat (exothermic).
AS is negative because the total entropy of the reactants is greater than that of the products (there are 4 moles of gas on reactant side compared to only 1 mole on the product side). Thus, the reactants are said to be "messier" than the products.
AG is negative at lower temperatures because at low temperatures, -TAS is more negative, resulting in the negative sign of AG.
Hope this helps.
Explanation:
A property that does no change the chemical composition of a substance are known as physical properties.
For example, mass, volume, size etc are all physical properties.
Whereas a property that changes the chemical composition of a substance are known as chemical properties.
For example, reactivity, toxicity etc are all chemical properties.
Therefore, identifying the given statements as follows.
- The various components of a mixture do not combine chemically - physical property.
- Chemical properties can only be observed during a chemical reaction - chemical property.
- The rusting of iron is a chemical reaction - chemical property.
- Melting and boiling points are physical properties - physical property.
