The metals are elements which have low ionization potential and can lose electrons easily
the other physical characteristics associated with them and hence with Aluminium are
a) they can conduct electricity in molten state, hence It would only conduct electricity if it were melted.
b) It could be stretched into a thin wire. It means it is ductile.
In case of given aluminium metal the correct answer is
it could be stretched to thin wire
Answer:
Explanation:
Nitrogen has the atomic number = 7
So, No. of electrons = 7
<u><em>Electronic Configuration:</em></u>
<u>Remember that:</u>
s sub shell holds upto 2 electrons while p sub shell upto 6
Answer : The millimoles of acetate need to add to this solution will be, 18.2 mmol
Explanation :
For acetic acid, 
Moles of of acetic acid = 10 mmol
pH = 5.00
Using Henderson Hesselbach equation :
![pH=pK_a+\log \frac{[Salt]}{[Acid]}](https://tex.z-dn.net/?f=pH%3DpK_a%2B%5Clog%20%5Cfrac%7B%5BSalt%5D%7D%7B%5BAcid%5D%7D)
Now put all the given values in this expression, we get:
Thus, the millimoles of acetate need to add to this solution will be, 18.2 mmol
Answer:
21.63 %
Explanation:
The molar mass of Mn₃[Mn(CO)₄]₃ is 665.64 g/mol.
Let's assume we have 1 mol of Mn₃[Mn(CO)₄]₃, if that were the case then we would have 665.64 grams.
There are 12 C moles per Mn₃[Mn(CO)₄]₃, with that in mind we<u> calculate the weight of 12 C moles:</u>
- 12 mol C * 12 g/mol = 144 g
Finally we <u>calculate the mass percent of carbon</u>:
- 144 g / 665.64 g * 100% = 21.63 %
