1) Do the sum of forces in a horizontal direction
2) Do the sum of forces in vertical direction
- The forces will be balanced if for each direction the net force is equal to zero.
- The forces will be unbalanced if for each direction the net force is nonzero.
Answer: B
Add the forces in the horizontal and vertical directions separately.
Answer:
% is 51.6% of Oxygen
Explanation:
According to the working in the photo
Answer:
The easiest way to identify a double displacement reaction is to check to see whether or not the cations exchanged anions with each other.
