Answer:
0.12 M
Explanation:
Step 1: Write the balanced equation
NaOH + HCl ⇒ NaCl + H₂O
Step 2: Calculate the reacting moles of NaOH
10 mL of a 0.30 M NaOH solution react.
Step 3: Calculate the reacting moles of HCl
The molar ratio of NaOH to HCl is 1:1. The reacting moles of HCl are 1/1 × 3.0 × 10⁻³ mol = 3.0 × 10⁻³ mol.
Step 4: Calculate the concentration of HCl
3.0 × 10⁻³ mol of HCl are in 25 mL of solution.
Answer: Skier 1 will have more potential energy because he is higher than skier 2
Explanation: Gravitational potential energy is the energy possessed by a body by virtue of its position or height.
P.E=
m= mass of the body
g= acceleration due to gravity
h= height of body
Thus if the masses of two bodies are same, the one with greater height possess greater potential energy.
