I would say Na. Oxygen has 2 valence electrons and when reacting with other molecules, the ones with the fullest or emptiest shells will react the least. Both H2 and Na are in the Alkali Metals in the first row, but since H2 has 2 molecules, it would use more oxygen than Ana

[tectonic activity].
Explanation:
What the team of geologists were talking about is known as the continental drift. The term continental drift which was introduced in the 1500s by people like Abraham Ortelius was mot accepted because the reasons backing it were not sufficient enough. The work on Continental drift was also worked on by people like Charles Lyell, Alfred Russel and Wegener. The term continental shift is used by geologists and other scientists to explain the movement of continents over time. The movement of continents is actually the movement on tectonic plates.
Although the movement of continents has not been accepted generally in those times, there has been modern evidence to back it up such as the record on fossils found in in several continents which are similar.
Diego‘s little brother should be told that different continents move at different rate and the movement is on the tectonic plates.
Answer:
to the right (products side)
Explanation:
The equilibrium constant K describes the ratio between the concentration of products and reactants at equilibrium. For a general reaction:
a A + b B → c C + d D
The equilibrium constant expression is:
A low value of K indicates that the concentration of products (C and D) is low in relation with the concentration of reactants (A and B).
Conversely, a high value of K indicated that the concentration of products is high compared with the concentration of reactants.
Since K = 6.4 × 10⁹ is a high value, the concentration of products is higher than the concentration of reactants at equilibrium. Thus, the position of the equilibrium is favored to the right.
