Answer:
1.38×10^25 molecules
Explanation:
Applying n= (no. of molcules)/NA
23 = N/6.02×10^23
= 1.38×10^25 molecules
Answer: 0.113 moles of NaCl are created as a result of decomposing 12 grams of .
Explanation:
To calculate the moles :
The balanced chemical equation for decomposition of is:
According to stoichiometry :
2 moles of give = 2 moles of
Thus 0.113 moles of give = of
Thus 0.113 moles of NaCl are created as a result of decomposing 12 grams of .
The ability to attract an electron for bonding is called (option B) Electronegativity.
PH is defined as the negative log of Hydrogen ion concentration. Mathematically we can write this as:
We are given the concentration of
. Using the value in formula, we get:
Therefore, the pH of the solution will be 3.745
