Below is the solution:
n equation showing conservation of mass of reactants and products:
<span>2H2O --> 2H2 & O2 </span>
<span>what is the mass of the oxygen gas produced, from 178.8 g H2O , (using molar masses: </span>
<span>178.8 g H2O @ (1mol O2)(@ 32.00 g/mol) / (2molH2O)(18.02g/mol) = </span>
<span>your answer (4 sigfigs): 158.8 g O2 </span>
<span>178.8 g H2O ---> 20.0 H2 & 158.8 O2</span>
From the given choices the true statement is Surface winds blow parallel to isobars.
Answer: Option B
<u>Explanation:</u>
The winds which flow near the isobars, flow in the parallel direction of the isobars. They are not absolutely parallel to each other but are this much parallel that the purpose of the flight planning can be fulfilled with this.
These winds flow in perpendicular position to isobars which are present at that particular surface and they flow in this direction due to the acting of the force of friction in that area. This force of friction can also change the direction and the flow of the wind.

Answer:
The main conclusion that can be determined by observing the map of Africa is that the borders of the nations of modern Africa were determined by the colonial powers that distributed the territories of the continent after the Berlin Conference. Thus, the present borders of the continent do not respect the historical nationalities that the African tribes give each other, with which ethnic conflicts occur in many of these nations, especially in central Africa. Thus, although today it is a practically impossible situation, in case of wanting to respect the historical nationalities of the peoples of the continent, the current national borders should be modified taking into account the ethnic, social and cultural differences of its inhabitants.
