Yasmin's teacher tells her that the solubility of salt is 360 g/L at room temperature 25 °C). How can Yasmin make an unsaturated salt solution? She can add 760 g of salt to 2 L of room temperature water (25 °C) and stir until it dissolves.

She can add 380 g of salt to 1 L of room temperature water (25 °C) and stir until it dissolves.

She can add 340 g of salt to 1 L of room temperature water (25 "C) and stir until it dissolves.

She can add 360 g of salt to 1 L of room temperature water (25 °C) and stir until it dissolves.

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
