Answer: tapeworm-human
Explanation:
Tapeworm, also known as Taenia solium is a parasitic nematode that gets into the human intestine, depriving humans of food nutrients. Its effects include diarrhoea, abdominal pains and general weakness of the human body.
Thus, the relationship of tapeworm and humans is parasitic because the tapeworm benefits at the human expense.

Answer:
4.5 moles H₂O
or
81.072 g H₂O
Explanation:
I am not exactly sure whether you want moles H₂O or grams H₂O. So, I'll calculate both. To find the moles H₂O, you'll need to covert moles C₈H₁₈ to moles H₂O via the mole-to-mole ratio from the reaction coefficients. To find the grams H₂O, you need to convert moles H₂O to grams H₂O via the molar mass.
2 C₈H₁₈ + 25 O₂ ---> 16 CO₂ + 18 H₂O
0.5 mole C₈H₁₈ 18 moles H₂O
----------------------- x ------------------------- = 4.5 moles H₂O
2 moles C₈H₁₈
Molar Mass (H₂O): 2(1.008 g/mol) + 16.00 g/mol
Molar Mass (H₂O): 18.016 g/mol
4.5 moles H₂O 18.016 g
---------------------- x ---------------- = 81.072 g H₂O
1 mole
Answer:
16
Explanation:
number of electrons should also be 16.
The answer is liquid or solid.
That is a substance that forms a vapor is generally in liquid or solid physical state.
The substance that is in liquid or solid physical state, forms vapor.
When heated solid and liquid can be converted into vapor so the answer is solid or liquid is the physical state that forms vapors.
