Assuming it has no electrical charge, your electron count would be equal to the atomic number.
The concentration of the solution is 5.0 molar, which is 5.0 mole/L. So in the 1.0 L of 5.0 molar KF salt solution, the moles of KF is 5.0molar*1.0L=5.0 mole. The molecular weight of KF is given in the question as 58.10 gram/mole, so the grams of KF is 58.10 gram/mole * 5.0 mole = 290.5 gram.
Particles are dissolved
Light beam passes through invisibly
Brownian movement is not discernible
I have gotten these answers checked and they are right.
By adding a lot of carbon dioxide of what is necessary could be harmful for living things, the carbon cycle is something natural, this cycle released enough carbon dioxide, as result not to damage living things so by adding more could prejudicial
The answer is c ..............::
