Yes and no it depends if your good at it you could also use a digital scale, but I perferr to use a balance scale
Answer:
4
Explanation:
Applying,
pH = 14-pOH.................... Equation 1
But,
pOH = -log(OH⁻)
Where OH⁻ = Hydroxyl ion concentration of NaOH.
From the question,
Given: OH⁻ = (1×10⁻¹⁰) M
Substitute these values into equation 1
pH = 14-log((1×10⁻¹⁰)
pH = 14-10
pH = 4
Hence the pH of NaOH with a molarity of 1.0 x 10-10M = 4
34g
Considering total mass as100g
I am sorry if it’s wrong
Answer:
The modern periodic table is arranged on order of increasing atomic number.
Explanation:
Modern periodic law states that the position of an element in the periodic table is a function of its atomic number.Atomic number is the number of electon(s) in a neutral atom and it determines the number of electon in the outermost shell of an atom called Group of an atom and also atomic determines the number of electonic shells called Period
this is opposed to the old periodic table in which elements were arranged based on their mass number
