The atom with the strongest attraction for electrons in bond formation is the atom with the most positive charge since an electron has a negative charge. Unlike attracts like. Among these, Sr and ba has 2+ and has the greatest charge but ba<span> has a stronger electron affinity (decreasing from top to bottom). answer is barium.</span>
Answer:
Potassium hydroxide + Hydrochloric acid → Potassium chloride + Water.
Answer:
22m/s
Explanation:
Given parameters:
Time = 5s
Acceleration = 4m/s²
Initial velocity = 2m/s
Unknown
Final speed = ?
Solution:
To solve this problem, we use the expression below;
v = u + at
v is the final speed
u is the initial speed
a is the acceleration
t is the time taken
So, insert the parameters and solve;
v = 2 + 4 x 5 = 22m/s
