Based on <span> Henderson - Hasselbach equation, we have
pH = pka + log </span>
Given: pH = 5.28 and [Acid] = 0.05 m,
∴ pKa = 5.28 - log (0.05) = 6.58
∴ Ka = 2.624 X
Thus, ionization constant of boric acid is 2.624 X
Answer:
The correct answer is B
Explanation:
This question seeks to test the difference between mass and weight.
Mass is a measurement of the amount of matter present in an object. While <u><em>weight is a measurement of the force of gravity pulling (the mass of) an object</em></u>. Hence, measuring the weight of the moon rocks in the moon might be a waste since the weight of the object on earth will produce a different value due to the difference in the force of gravity between the earth and the moon.
Answer:
False
Explanation:
In Nuclear plants accidents such as explosions can occur which may lead to loss of life or severe injuries.
Nuclear energy production does not produce emissions but it produces radioactive waste which have to be stored adequately to prevent pollution. Since nuclear waste cannot be destroyed, measures have to be taken to adequately store the waste.
If the nuclear plant is being attacked, it can be used as a nuclear weapon to create disaster
C) it is made up of carbon, hydrogen, and oxygen
D) it is a compound made of twenty-four total atoms of three different elements
they are both right but I would go with D
