Explanation:
Cell theory is one of the most basic principles of biology in which living organisms are made up of cells
What is occurring at segment DE of the graph is boiling.
At point A- We are adding temperature, from A-B we are just heating the solid molecules, from point B-C, temperature is not changing but time is elapsing(solid is melting). At Point C its completely in liquid state. From point D to E liquid molecules start to heat up and evaporation occurs. From point E-F we are just heating s<span>team.</span>
Answer : The balanced redox reaction will be,
Explanation :
The given chemical equation is,
In the half reaction method, the number of atoms in each half reaction and number of electrons must be balanced.
The half reactions in the acidic medium are :
Reduction : ......(1)
Oxidation : .......(2)
Now multiply the equation (1) by 2 and equation (2) by 3 then added both equation, we get the balanced redox reaction.
Thus, the balanced redox reaction will be,
Answer 1) Option D) 3 moles.
Explanation : In the reaction we can see that the number of moles of hydrogen are equal to the number of water molecules formed. Also, oxygen is found t o be the limiting reactant as equal number of moles are not produced in the reaction.
Here when we use 3 moles of hydrogen then 3 moles of water will be produced. As we are ignoring the moles of oxygen here as that is a limiting reactant.
Answer 2) Option A) 9 moles of reactants chemically change in to 11 moles of product.
Explanation : We can see that 1 mole of pentane reacts with 8 moles of oxygen to produce 5 moles of carbon dioxide and 6 moles of water. So when we add the reactants side we get 1 + 8 = 9 moles and in products it has 5 + 6 = 11 moles.
Hence, 9 moles of reactants produce 11 moles of products.
Answer 3) Option A) 0.62 moles.
Explanation : Here, the number of moles of Cu reacts with 2 moles of silver nitrate and gives 1 mole of copper nitrate and 2 moles of silver.
So, the ratio is 1 : 2 in the reactants side, Now, when we have 1.23 moles of silver nitrate then to calculate the number of Cu.
we can simply cross multiply and get the answer as 1.23 / 2 = 0.615 = ~ 0.62 moles.
