Answer: Option (c) is the correct answer.
Explanation:
Temperature is used as for measuring the average kinetic energy present in a substance or object.
The internal kinetic energy obtained by the molecules of an object is known as thermal energy.
Hence, temperature measures the thermal energy of an object.
Whereas when this thermal energy flows from a hotter object to a cooler object which are placed adjacent to each other then it is known that heat is flowing.
Thus, we can conclude that heat differ from temperature as temperature measures thermal energy, and heat is the flow of thermal energy.

<h3>What is Balanced Chemical Equation ?</h3>
The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
The given reaction balanced equation is:
Zn(s) + MnO₂(s) + H₂O(l) → ZnO(s) + Mn(OH)₂(s)
<h3>How to find the number of moles ?</h3>
To find the number of moles use the expression:
Number of moles = 
Here,
Mass of Zn = 4.50 g
Molar mass of Zn = 65.4 g/mol
Now put the value in above expression
Number of moles of Zn =
= 
= 0.068 mol
Mass of MnO₂ = Moles of MnO₂ × Molar mass of MnO₂
= 0.068 mol × 86.9368 g/mol
= 5.911 g
Mass of H₂O = Moles of H₂O × Molar mass of H₂O
= 0.068 mol × 18.0 g/mol
= 1.224 g
Thus from the above conclusion we can say that 5.911 grams of manganese dioxide and 1.224 gram of water are consumed.

Answer:
Rocks are the aggregate of minerals. There are three distinct categories of rocks, namely the sedimentary, metamorphic and the igneous rocks.
- The sedimentary rocks are formed from the deposition, compaction, and lithification of soft sediments that are transported from one place to another by the agents such as wind, water, and ice. For example, Sandstone and Shale.
- The metamorphic rocks are derived from the previously existing sedimentary, igneous or other metamorphic rocks, due to the influence of extremely high pressure as well as temperature conditions. For example, Quartzite and Marble.
- The igneous rocks are those rocks that are formed from the cooling and crystallization of magma. For example, Granite and Diorite.
All these three types of rocks are formed by different processes and their mode of origins are also different.
Given :
Mass of 
is 571.6 g per liter .
Density of solution , 
.
To Find :
a. Mass percentage
b. Mole fraction
c. Molality
d. molarity of H2SO4 in this solution.
Solution :
Molar mass of , m = 1329 g/mol .
a ) Mass of contain in 1 liter is 1329 g .
b ) Moles of = 
.
Moles of 
= 
.

Hence , this is the required solution .
Let's write the balanced chemical reaction for this:
K₂CrO₄ + Pb(CH₃COO)₂ --> PbCrO₄ + 2 CH₃COOK
The products are lead(ii) chromate and potassium acetate. As you can notice, there is an exchange of ions involved for both reactants. This type ofreaction is called the <em>double-replacement reaction or also called metathesis</em>.
