Answer:
D
Explanation:
Lithium has one valence electron, so it has one to give away to have an outer shell of 8.
Sulfur has 6 valence electrons, so it needs 2 to get an outer shell of 8.
If we have two Li, that means sulfur will get 2 e- and Li will give away 2 e-, so the formula is Li₂S.
Nitrogen
Oxygen
Water Vapor
Carbon Dioxide
Methane
Nitrous Oxide
Ozone

Answer:
Answer) The first box represent the budding type of asexual reproduction . In budding due to the cell divison at the particular place in the organism , new individual will produced.
Second picture represent the budding in hydra. Budding is also a asexual reproduction.

A.
An amine refers to a nitrogen-based compound. Since A is the only option with nitrogen, that would be the answer.
Answer:
Sodium iodide NaI
Magnesium chloride MgCl₂
Explanation:
Silicon dioxide SiO₂ it is not soluble in water, so it can not be recrystallized from water, it is a white solid and the boiling point is 2230 °C. This one is not the unknown solid.
Sodium iodide NaI it is soluble in water, it has a white color and the boiling point is 1304 °C
. This can be the unknown solid.
Magnesium chloride MgCl₂ is soluble in water, it have a white color and the boiling point is 1,412 °C
. This can be the unknown solid.
Phosphorus tribromide PBr₃ is will start a hydrolysis reaction in water, it is a colorless liquid and it has a boiling point of 173 °C. This one is not the unknown solid.
