Answer:
0.0991 M
Explanation:
Step 1: Write the neutralization reaction between oxalic acid and sodium hydroxide.
H₂C₂O₄ + 2 NaOH = Na₂C₂O₄ + 2 H₂O
Step 2: Calculate the moles of oxalic acid
The molar mass of H₂C₂O₄ is 90.03 g/mol. The moles corresponding to 153 mg (0.153 g) are:

Step 3: Calculate the moles of sodium hydroxide
The molar ratio of H₂C₂O₄ to NaOH is 1:2.

Step 4: Calculate the molarity of sodium hydroxide

Answer:
Car B has a greater momentum than car A
Explanation:
Given data:
Mass of car A = 1200 Kg
speed of car A = 22 km/hr
Mass of car B = 1200 Kg
speed of car B = 25 Km/hr
Solution:
For car A:
p = mv
p = 1200 Kg × 22 km/hr
p = 26400 kg.km/hr
For car B:
p = mv
p = 1200 Kg × 25 km/hr
p = 30,000 kg.km/hr
Greater amplitude waves have more energy and greater intensity, so they sound louder. ... The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less. This explains why even loud sounds fade away as you move farther from the source.
