Answer: The correct option is A.
Explanation: The given molecules are the molecules of same element.
These molecules are considered as diatomic species.
Polar molecules are the molecules in which some polarity is present in the bond. These molecules are formed when there is some difference in the electronegativities of the elements. Example: HCl
Non-polar molecules are the molecules where no polarity is present in the bond. These molecules are formed when there is no difference in the electronegativities of the elements. Example: 
The given molecules are non-polar in nature.
Hence, these molecules must be non-polar. So, the correct option is A.
Answer:
According to the Environmental Paper Network's Paper Calculator, it takes about 32 million BTUs of energy to produce 1 ton of virgin paper fiber. To produce 1 ton of recycled paper, it takes about 22 million BTUs.
so the answer could be it takes less Btu to manufacture recycled products than new ones

Explanation: If children were running around with balloons filled with hydrogen gas, then they would catch fire. So the answer to your question is, its simply dangerous.
Answer:
A - A fruit of vegetable will begin to grow
Answer:
0.716
Explanation:
First, write the balanced equation:
3 H2CO3 + 2 Fe(OH)3 ----> Fe2(CO3)3 + 6 H2O
Second, go from the molarity of H2CO3 to liters of Fe(OH)3
(Pull mole ratio from balanced equation)
1.22/1L x 0.0880/1 x 3molH2CO3/2molFe(OH)3 x 1/0.225L
Use calculator, and you end up with 0.7157333
Round to 0.716
