Answer:
It is basic.
Explanation:-
Given hydrogen ion concentration [H+] = 1×10^-12
Using the formula
pH = - log [H+]
= - log [ 1 x 10^-12]
= 12
Since the pH is more than 7, the chemical is basic
Answer:
Δ
N = -1
Explanation:
Step 1: Data given
2 SO2(g) + O2(g) ⇌ 2 SO3(g)
For 2 moles of SO2 we need 1 mol of O2 to produce 2 moles of SO3
Step 2: Calculate Δ
Δ
N wNill be the sum of moles of products minus the sum of moles of reactants.
Number of moles of products = number of moles of SO3 = 2
Number of moles of reactants = number of moles of SO2 + number of moles of O2 = 2 + 1 = 3
Δ
N = 2 - 3 = -1
