thank you have a great April fool weekend
Answer: The volume of 0.235 M 
needed to titrate 40.0 mL of 0.0500 M 
is 8.51 ml
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
We are given:
Putting values in above equation, we get:
Thus volume of 0.235 M needed to titrate 40.0 mL of 0.0500 M is 8.51 ml
Answer:
Explanation:
In S₈ , there are 8 single bonds which breaks up first . Energy absorbed
= 8 x 240 = 1920 kJ
In S₈ four double bonds of S₂ are formed . Let bond energy be x . In this process energy will be released . energy released in four S₂ molecules formed = 4 x
Given
1920 + 4x = 239
4x = 239 - 1920
x = - 420.25 kJ .
So bond energy of S₂ = 420.25 kJ .
Answer:
Respiration is considered as exothermic reaction because energy is released in this process. Glucose combines with oxygen present in our cells to form carbon dioxide and water along with energy.
Explanation:
Good Luck!
Answer:
There are a total of 8 electrons around the carbon, in 4 pairs. Because there are 4 bonds, these are all bond pairs. Each double bond uses 2 bond pairs - which are then thought of as a single unit.
