Answer:
The electron configuration of an element is the arrangement of its electrons in its atomic orbitals. By knowing the electron configuration of an element, we can predict and explain a great deal of its chemistry.
Answer:
The answer to your question is below
Explanation:
a) HCl 0.01 M
pH = -log [0.01]
pH = - (-2)
pH = 2
b) HCl = 0.001 M
pH = -log[0.001]
pH = -(-3)
pH = 3
c) HCl = 0.00001 M
pH = -log[0.00001]
pH = - (-5)
pH = 5
d) Distilled water
pH = 7.0
e) NaOH = 0.00001 M
pOH = -log [0.00001]
pOH = -(-5)
pH = 14 - 5
pH = 9
f) NaOH = 0.001 M
pOH =- log [0.001]
pOH = 3
pH = 14 - 3
pH = 11
g) NaOH = 0.1 M
pOH = -log[0.1]
pOH = 1
pH = 14 - 1
pH = 13
Answer:
![m=7.24x10^3g](https://tex.z-dn.net/?f=m%3D7.24x10%5E3g)
Explanation:
Hello!
In this case, since 6.00x10²³ atoms of any element is related to one mole of atoms via the Avogadro's number, and the molar mass of xenon is 131.3 g/mol, we obtain the following mass in grams of xenon:
![m=3.32x10^{25}atoms*\frac{1mol}{6.022x10^{23}atoms}* \frac{131.3g}{1mol} \\\\m=7.24x10^3g](https://tex.z-dn.net/?f=m%3D3.32x10%5E%7B25%7Datoms%2A%5Cfrac%7B1mol%7D%7B6.022x10%5E%7B23%7Datoms%7D%2A%20%5Cfrac%7B131.3g%7D%7B1mol%7D%20%5C%5C%5C%5Cm%3D7.24x10%5E3g)

Answer:
Carbon has six electrons (2 core and 4 valence), and can form four bonds with neighboring atoms. Nitrogen has seven electrons (2 core and 5 valence)(1s2, 2s2, 2px1, 2py1, 2pz1). So if you are following the rules, you might well assume that nitrogen would be able to form five bonds (after all, it has five valence electrons.)
Answer:
d
Explanation:
its d because a beta particle has a negative charge
