Answer: 14.62 ml
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
where,
n= moles of solute
= volume of solution in ml = 250 ml
Now put all the given values in the formula of molarity, we get
To calculate the volume of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Thus the volume of NaOH solution the student will need to add to reach the final equivalence point is 14.62 ml
Answer:
<h2>2Na(g) + Cl2 (g) --> 2NaCl(s)</h2>
Explanation:
- Such type of chemical reaction in which change in oxidation state takes place due to loss and gain of electrons is known as a redox reaction.
- Such type of the species that lose electron is called reducing agent and the process is known as oxidation because the species is oxidized by losing an electron and thus acts as a reducing agent.
- Such type of the species that gain electron is called an oxidizing agent and the process is known as reduction because the species is reduced and thus acts as the oxidizing agent.
- In the given options, only the oxidation number changes in the reaction such as , so it is a form of the redox reaction.
- In this reaction, Na atom changes into ion and the Cl atom converts into ion that means a change in oxidation states occurs 0 to +1 in the case of Na atom and 0 to -1 in the case of Cl atom. In others options, there is no change in the oxidation state so they are not redox reactions.
Answer:Carbon enters the soil through the decomposition of organic material. When plants die or leaves fall off of trees, for example, they fall to the soil
