Answer:
C. move left
Explanation:
The object will move towards the left direction due to the unbalanced forces that are acting on it.
The resultant force on the object will be 1N in the left direction
- The resultant force on a body is that singular force that will have the same effect as the different forces that acts on a body
- When forces acts in opposite directions, they are subtracted
- The object will move in the direction of the one with the greater force
So;
Resultant force = 26N - 25N = 1N
The body moves 1N to the left
The molar concentration of the original HF solution : 0.342 M
Further explanation
Given
31.2 ml of 0.200 M NaOH
18.2 ml of HF
Required
The molar concentration of HF
Solution
Titration formula
M₁V₁n₁=M₂V₂n₂
n=acid/base valence (amount of H⁺/OH⁻, for NaOH and HF n =1)
Titrant = NaOH(1)
Titrate = HF(2)
Input the value :
Mercury is the smallest and closest plant to the sun
