Jesse travels 3.0 meters east and then turns and travels 4.0 meters north. What distance did Jesse travel? 1 m 5 m, northeast 7
m 7 m, northeast
2 answers:
Answer : The correct option is, 7 m
Explanation :
Distance : It is defined as the how much distance is covered by an object during the motion. It is a scalar quantity that means it does not depends on the direction.
Displacement : It is defined as the change in the position of an object. It is a vector quantity that means it has magnitude and as well as direction.
According to the question,
The distance traveled by jesse towards east = 3.0 m
The distance traveled by jesse towards north = 4.0 m
The total distance traveled by jesse = 3.0 m + 4.0 m = 7.0 m
Hence, the distance traveled by jesse is, 7 m

Explanation:
First step is to find the number of moles of oxalic acid.
n(oxalic acid) =
Now use the molar ratio to find how many moles of NaOH would be required to neutralize of oxalic acid.
n(oxalic acid): n(potassium hydroxide)
1 : 2 (we get this from the balanced equation)
: x
x = 0.0111 mol
Now to calculate what concentration of KOH that would be in 25 mL of water:
