B. 1 mole of beryllium, 2 moles of oxygen, 2 moles of hydrogen
Answer is: solution A has 2,57 time greater pH value than solution B.<span>
</span>Concentration of [H⁺] in solution A is than 370x.
pH = -log[H⁺].
pH(solution A) = -log(370x).
pH(solution b) = -log(x).
pH(solution A) / pH(solution B) = -log(370x) / -log(x).
pH(solution A) / pH(solution B) = 2,57.
Answer:
4 Fe + 6 02 ----> 2 Fe2O3
Explanation:
you need 4 iron and 6 oxygen in each side
Older trees can survive with the bark stripped from up to half the trunk diameter. If the bark is stripped all the way around the tree, it will die unless the damage can be repaired with bridge grafts.
