Answer:
millions
Explanation:
the 1 is seven decimbal places to the left (seven places left of zero), which is the millions place
To name the binary ionic compounds it is necessary to observe which is the metal and the non-metal that compose them.
This name is made as follows:
- The name of the metal is shown.
- The name of the non-metal is presented in abbreviated form.
- Add the suffix "ide" at the end.
An example of this can be seen in the binary ionic composite KCL that receives the name Potassium Chloride, since potassium is the metal and chlorine is the non-metal.
It is important to remember that binary ion compounds are electrically charged ionic molecules formed by a metal and not a non-metal.

Answer:
She can add 380 g of salt to 1 L of hot water (75 °C) and stir until all the salt dissolves. Then, she can carefully cool the solution to room temperature.
Explanation:
A supersaturated solution contains more salt than it can normally hold at a given temperature.
A saturated solution at 25 °C contains 360 g of salt per litre, and water at 70 °C can hold more salt.
Yasmin can dissolve 380 g of salt in 1 L of water at 70 °C. Then she can carefully cool the solution to 25 °C, and she will have a supersaturated solution.
B and D are wrong. The most salt that will dissolve at 25 °C is 360 g. She will have a saturated solution.
C is wrong. Only 356 g of salt will dissolve at 5 °C, so that's what Yasmin will have in her solution at 25 °C. She will have a dilute solution.
The answer is 0.492 because there are 100 meters in a hectometer, and 49.2/100 is 0.492
