Answer:
False.
Explanation:
Friction is a resisting force that acts on a body to prevent its motion. Friction force acts opposite to the direction of motion.
Answer:
200 g of NaOH
Explanation:
For this solution of NaOH
2.50 M means that in 1L of solution, we have 2.5 moles
Mol . molar mass = Mass
2.5 m . 40 g/m = 100 grams
In 1 L, we have 100 grams of solute, so in 2L, we have the double
200 g of NaOH
Answer:
Answer: 882mmHg
Explanation:
In a closed-end manometer, the gas added is under a pressure that is measured against atmospheric pressure. The difference in pressure between both gases is equal to the difference in mercury levels. Thus, the pressure of the argon can be:
783 mmHg - 96.0mmHg = 687mmHg
783 mmHg - 96.0mmHg = 879mmHg
Based on the options, the possible answer (The nearest to the second value) is:
