I think you just do 11.29 multiplied by 186 since to find density you divide mass by volume. So 186 divided by x is 11.29. So in conclusion the volume would be 2,099.94mL
First one??
I believe this is the correct answer
Answer: Fe2O3
Explanation:
5.60 g Iron Oxide
- 3.92 g Iron
===========
= 1.68 g Oxygen
Convert Fe and O to moles:
3.92 g Iron/55.85 = 0.0702 moles Fe
1.68 g Oxygen/16 = 0.105 moles O
The ratio of O to Fe is 1.50. There are 3/2 O for each Fe. Multiply by 2 to get whole numbers: 2Fe for every 3O: Fe2O3
Answer: Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers—plants or algae—and nothing else. For example, a grasshopper living in the Everglades is a primary consumer
The most electronegative element will have atoms with strongest association for electrons. Electronegativity is the ability of an atom to attract electrons and form bonds with electrons. . In the periodic table the left hand side favors the loss of electrons because less energy is required to lose an electron than to gain an electron. On the other han, the right hand side favors gaining electrons since less energy is required than when losing electrons.
Henceforth, from left to right in the periodic table the tendency to gain electrons increases. In contrast, going down a group there is decreased association for electrons, because atomic radius increases which suggests that valence electrons are further away from the nucleus.This makes fluoride the ion with strongest association of electrons. The noble gases have a complete shell so cannot attract electrons to themselves, which means they have no electronegativity.
