In the figure above, the solid line shows the expected result of steadily decreasing the volume, thus increasing the pressure of a sample of gaseous hydrogen fluoride at a constant temperature of 100 degrees celcius. The normal boiling point of HF (g) is 19.5 degrees celcius. The dashed line shows the actual result when the experiment was carried out. Which of the following BEST accounts for the observed behavior?

Which of the following is not true about the atomic model of substances?

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.

What type of chemical reaction occurs between silver nitrate (agno3) and copper (cu)? the equation i was given is 2agno3 + cu —> 2ag+ cu(no3)2.
