Answer:
Given that W=mg:
The weight of the box would be 50 N taking the value of 'g' as 10ms-2. Taking the value of 'g' as 9.8ms-2, the weight of the box would be 49 N.
(N = Newtons)
Answer:The dissociation constant of a weak acid is 4.9 ~ 10-8 , its percentage ionization at 0.1 M is ( a ) ... The pH of a 0.1 M aqueous solution of a weak acid ( HA ) is 3.
Explanation:acid. Ka acetic acid = 1.8χ10–5. (b) A buffer solution is prepared by adding 0.10 liter of 2.0 ... Compute the hydrogen ion concentration of the buffer solution.
Answer: D) covalent bonds are stronger than ionic bonds
