<u>Answer:</u> The correct answer is from the substance being oxidized to the substance being reduced.
<u>Explanation:</u>
Redox reaction is defined as the reaction in which oxidation and reduction reaction occur simultaneously.
Oxidation reaction is defined as the reaction where an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.
Reducing agents are defined as the agents which reduces the other substance and itself gets oxidized. These agents undergoes reduction reactions.
Reduction reaction is defined as the chemical reaction where an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
Oxidizing agents are defined as the agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions.
Electrons are transferred from one atom to another in this type of reaction from the substance which is getting oxidized to the substance which is getting reduced.
It can also be said that, electrons are transferred from reducing agent to the oxidizing agent.
Hence, the correct answer is from the substance being oxidized to the substance being reduced.
Density = mass / volume
therefore, both mass and volume are needed
the first one represents volume
The Space it occupies is the answer
Answer:
Radiation
Conduction
Convection
Explanation:
<u>Radiation:</u> Transfer of heat by electromagnetic rays (Example: A microwave heating food)
<u>Conduction:</u> Transfer of heat energy from one object to another through direct contact (Example: Getting out of bed and your warm feet touch cold tile, making the tile warm and your feet cold)
<u>Convection:</u> Movement of heat by a fluid such as air or water (Example: A convectional oven works by heating the air inside the oven to evenly cook food)

Answer:- 
Explanations:- Lattice energy depends on two factors, charge and size.
High charge and small size gives higher lattice energy where as low charge and bigger size gives lower lattice energy.
in LiCl, NaCl and KCl, the anion is same and also the charges for Li, Na and K are also same. The deciding factor here is the size of cations. Since the size increases as we move down a group, the order of size of these three atoms is Li<Na<K.
The order of lattice energy is exactly opposite as it's increases as the size decreases.
Now, if we look at magnesium chloride and strontium chloride then again the anion is common but the metals have higher charge as compared to the alkali metals(Li, Na and K). So, lattice energy values must be higher for these two compounds. If we compare Mg and Sr then size of Mg is smaller and so the lattice energy would be greater for this.
Hence, the increasing order of lattice energy is .
