Q3. A bridge is built without expansion gaps.
Explain what could happen to the bridge if the temperature became:
a) much hotter than the day it was built.
b) much colder than the day it was built.
P.s. (this is not a select option question, explain each according to the question)
Answer: 127.5ml
Explanation:
To calculate the volume of acid, 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 KOH.
We are given:
Putting values in above equation, we get:
Thus 127.5 ml of 0.5M of HNO3 would be needed to react with 85ml of 0.75M of KOH
Answer:
²⁵⁰₉₆Cm → ²⁴⁶₉₆Cm + 4 ¹₀n
Explanation:
The complete equation is;
²⁵⁰₉₆Cm → ²⁴⁶₉₆Cm + 4 ¹₀n
- The above equation is an example of a nuclear reaction in which unstable atom of Cm emits neutrons to become more stable.
- Radioactive isotopes undergo radioactivity or decay to attain stability, they do so by emitting particles such as alpha, beta particles or a neutron.
- An atom of Cm-250 undergoes decay and emits four neutrons to form an atom of Cm-246.
