Answer:
This effect is caused by increased levels of carbon dioxide, chlorofluorocarbons and other gases in the air, many of them released by human activity. greenhouse effect The warming of Earth's atmosphere due to the buildup of heat-trapping gases, such as carbon dioxide and methane.
Explanation:
0.24J/g*degC * 4.37g * 2.5degC = 2.622J
The 2.5 degC is the difference between 25 and 27.5 deg C.
Answer:
True
Explanation:
Earth is a single interconnected system but it can be subdivided into smaller systems.
Answer:
Carbon-Carbon Bonds
Carbon can form single, double, or even triple bonds with other carbon atoms. In a single bond, two carbon atoms share one pair of electrons. In a double bond, they share two pairs of electrons, and in a triple bond they share three pairs of electrons
Answer:
The final concentration of KCl is 4%
Explanation:
This is a solution with KCl and water.
12% it's a way of concentration that indicates, that in 100 mL of solution, we have 12 g of solute.
If we add 200 mL to this solution, we also have 12 g of solute but now, we have to calculate the new concentration.
New volume = 100 mL + 200 mL → 300 mL
Let's make a rule of three
In 300 mL we have 12 g of solute
In 100 mL we have (100 .12) / 300 = 4
