Types of matter are just different ways molecules behave at certain temperatures. There's no specific atoms or molecules that make solids, liquids, or gases. Ice, water, and water vapor are all H2O, for instance. The only correct answer would be that it is made of the same basic particles, but then again, so is everything.
The atom that has 7 valence electrons is A. fluorine.
It is in the halogens group.
It needs 1 more electron to become stable, therefore, it is highly reactive.
1. D. 5
2. B. 2
3. A. fluroine
Hope this helps you!!
Have a wonderful day!
The molar amount of gas can most likely be found by using the ideal gas law. This is because the ideal gas law states pV = nRT. P, V, and T are the pressure, volume, and temperature, which are the known variables. The R stands for the Universal Constant of Gases; also known. Therefore, the unknown is n, the number of moles (molar amount) of gas, and so you would solve for n from the law.
Answer: A) The molar amount of gas
