Answer:
[H₃O⁺] = 0.05 M & [OH⁻] = 2.0 x 10⁻¹³.
Explanation:
- HNO₃ is completely ionized in water as:
<em>HNO₃ + H₂O → H₃O⁺ + NO₃⁻.</em>
- The concentration of hydronium ion is equal to the concentration of HNO₃:
[H₃O⁺] = 0.05 M.
∵ [H₃O⁺][OH⁻] = 10⁻¹⁴.
<em>∴ [OH⁻] = 10⁻¹⁴/[H₃O⁺] </em>= 10⁻¹⁴/0.05 = <em>2.0 x 10⁻¹³.</em>
Answer:
mass of a particular object remains the same where ever it is placed, the mass will remain the same whether the object is on the moon or earth, unlike weight which will change.
Weight is affected by gravity. Therefore it is dependent on gravity or directly proportional to the force of gravity.
weight = mass × gravity
The gravity on earth is much larger than the gravity on the moon. Therefore the weight of an object weighs heavier on earth than on the moon. The object when placed on the moon will have a lower weight.
The difference is that the weight of the object on the moon will be lower than the weight of the object on earth.
The similarity is that the mass of an object will remain the same, regardless if it's placed on the moon or earth.
Hope this helps.
The material that absorbs the heat of the system is water owing to its high specific heat capacity.
The specific heat capacity of a substance refers to the amount of heat that is capable of increasing the temperature of 1 Kg of a body by 1 K. The higher the specific heat capacity, the more the amount of heat that the body can absorb without temperature change.
The material that absorbs the heat of the system is water because water has a higher specific heat capacity than all the other materials present.
