Answer:
11.0 L
Explanation:
The equation for this reaction is given as;
2H2 + O2 --> 2H2O
2 mol of H2 reacts with 1 mol of O2 to form 2 mol of H2O
At STP;
1 mol = 22.4 L
This means;
44.8 L of H2 reacts with 22.4 L of O2 to form 44.8 L of H2O
In this reaction, the limiting reactant is H2 as O2 is in excess.
The relationship between H2 and H2O;
44.8 L = 44.8 L
11.0 L would produce x
Solving for x;
x = 11 * 44.8 / 44.8
x = 11.0 L

Answer:
Explanations provided below
Explanation:
1. The first graph shows us that between 800,000 BCE and 2015 CE, the atmospheric concentration of carbon dioxide was fluctuating between 170 ppm and 300 ppm periodically, meaning it would achieve a maximum value, then drop down to a minimum value and the process would repeat over years by negligible changes in the maximum and the minimum values.
However, of 1950 to 2015 CE, we see a steady exponential growth of the atmospheric concentration of carbon dioxide strongly exceeding any other peak values seen in the trends before.
2. Similar patterns are seen in evolution of sulfur dioxide gases as well, as sulfur dioxide is another gas causing environmental problems (acid rains) which increased in concentration significantly after industrial revolution.
3. We may conclude that in the following years, the levels of carbon dioxide will remain to rise, as it reached its greatest value throughout the ages and is still rising exponentially.
4. Notice that we see the rise from around 1850. This was caused by the industrial revolution and an excessive usage of machines and power plants, as well as production of the first cars, which all contributed significantly to the amount of carbon dioxide released into the surroundings.
