The balanced equation is C6H14(g)
+ 19/2O2(g) → 6CO2(g) + 7H2O(g). If you are given 7.9 moles C6H14, multiply it
by a ratio of 19/2/1 to get the moles of oxygen. Then, you will get 75.05 moles
of O2.
Answer : The correct option is, 12.40
Explanation : Given,
Concentration of ion = 0.025 M
First we have to calculate the pOH.
Now we have to calculate the pH.
Therefore, the pH of a solution is, 12.40
Answer:
we would need to see questions 35-37 in order to answer the question
Answer:
When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4 and atomic number 2 less than the starting atom.
Explanation:
Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4 and atomic number 2 less than the starting atom.
Properties of alpha radiation:
Alpha radiations can travel in a short distance.
These radiations can not penetrate into the skin or clothes.
These radiations can be harmful for the human if these are inhaled.
These radiations can be stopped by a piece of paper.
