Answer: <span>the main anthropogenic greenhouse gas produced in the united states.
Anthropogenic means that the man is the responsible for its generation.
Fuel consumption for vehicles, factories and houses generates huge amounts of CO2.
</span>
Let's review the other options:
<span>a. the
most abundant greenhouse gas
FALSE: The most abundant greenhouse gas is water vapor.
b. the most potent (per molecule) gas. of the
greenhouse gases
Methane is considered more potent than CO2 as heat-trapping.
c. the only greenhouse gas presently decreasing in the
atmosphere
CO2 has not decreased but increased.
d. the main anthropogenic greenhouse gas produced in the united
states
TRUE as stated initially
e. the only greenhouse gas presently increasing in the atmosphere
FALSE: Methane (CH4) is also increasing.

➷ The formula for Potassium oxide is K2O
This is because potassium has a 1+ charge and the oxygen has a 2- charge. Two potassium atoms are required to balance the charge.

Answer:
A saturated fatty acid has the maximum possible number of hydrogen atoms attached to every carbon atom. It is therefore said to be “saturated” with hydrogen atoms. Some fatty acids are missing one pair of hydrogen atoms in the middle of the molecule.
Answer:
.13 moles
Explanation:
To begin this problem:
First you need to find the molar mass of acetamide, to do so:
- C=12g, H=1.008g, O=16g, and N=14g
- 2(12)+5(1.008)+1(16)+1(14)=59.04
To find moles when given grams, we divide grams by the molar mass.
- 7.8g/59.04g/mol=.13 moles
Using 2 sig figs from what we are given, this is our final answer.
Answer:
<u><em>(A.) three dimensional folded structure of the protein</em></u>
Explanation:
The secondary structure of a protein is a regular structure built from interactions between neighboring amino acids as the polypeptide starts to fold or coil into its functional three-dimensional shape.
The two kinds of secondary structures arising from this polypeptide 'flexing' are either the α-helix and β-pleated structures, all of which are vital to globular and fibrous proteins.
