Answer:
3.937 x 10⁻⁸ inches
Explanation:
Data Given:
Atomic radium in pm (picometer) = 1.00 x 10² pm
Atomic radium in inches = ?
1 pm = 10⁻¹² m
Solution:
First convert picometer to meter
As we Know
1 pm = 10⁻¹² m
then
1.00 x 10² pm = X meter
Do cross multiplication
X meter = (1.00 x 10² pm)(10⁻¹² m) / 1 pm
X meter = 1 x 10⁻⁹ m
So, 1.00 x 10² pm equal to 1 x 10⁻⁹ m
Now convert meter to inches
As
1 m = 39.37 inches
1 x 10⁻⁹ m = X inches
Do cross multiplication
X inches = (39.3701 inches)(1 x 10⁻⁹ m ) / 1 m
X inches = 3.937 x 10⁻⁸ inches
So,
1.00 x 10² pm = 3.937 x 10⁻⁸ inches
so the radius is 3.937 x 10⁻⁸ inches
D is an alkene because the ending is cis-2-pentene if it was an alkane is would be pentane.
Answer:
Two non bonded electron pairs and four bonded electron pairs
Explanation:
An image of the compound as obtained from chemlibretext is attached to this answer.
The ion ICl4- ion, is an AX4E2 ion. This implies that there are four bond pairs and two lone pairs of electrons. As expected, the shape of the ion is square planar since the lone pairs are found above and below the plane of the square. This is clear from the image attached.
Answer:
Metallic character decreases, and electronegativity increases.
Explanation:
Hello!
In this case, according to the organization of the periodic table, we can see that from left to right, the electronegativity increases as nonmetals are able to attract electrons more easily than metals.
Moreover, in contrast to the previous periodic trend, the metallic character decreases from left to right because the elements tend to decrease the capacity to lose electrons and consequently start attracting them.
Thus, the answer would be: "Metallic character decreases, and electronegativity increases".
Best regards!
