Polar bond.
A very common example is H2O.
The oxygen atom has an electronegativity value of about 3.5, while the hydrogen atoms have a value of about 2.2 (each).
Electronegativity describes how “greedy” atoms are with sharing electrons.
Since the oxygen atom has a greater value, it will be more “greedy” with the electrons.
Radium, which has an atomic number of 88. The Alkaline earth metals are in the second column of the Periodic Table. Hope this helps!
Answer:
Choices 2 and 4
Explanation:
HCL is formed witthe the elements Hydrogen and Chlorine. Whatever is on the left side of the equation must match up with the right side of the equation.
2. H + Cl --> HCl (we have one hydrogen and one chlorine)
4. 2HCl --> H2 + Cl2 (since the two is distributed to both the H and the Cl, H has 2 and Cl has two on the left side AND on the right side of the equation)
The correct is this because they said
Answer:
For each scenario as following:
A. 3 Potential deaths by chlorine exposure
B. 1 Potential deaths by chlorine exposure
C. 3 Potential deaths by chlorine exposure
Explanation:
According to Freitag, 1941 Chlorine exposure can be lethal at the concentration of 34-51 ppm in a time of 1h-1.5h. The answers are based on his reference.
