Every electron carries one elementary negative charge. Concerning mass,
it takes roughly 1,840 electrons to make enough mass for 1 proton or 1 neutron.
Electrons don't necessarily have to stay connected to an atom, but when they do,
they circle the nucleus.
So you should select (C): ==> Negative, ==> light, ==> circling the nucleus.
The formula for density is density =
. Substituting the given, the density is 162.69 g/cm3.
Answer: strongly acidic
Explanation: a strongly acidic solution has a pH between one and four
When the temperature is cold, barely any of the liquid rises, so most of it is at the bottom.
When the temperature is hot, the liquid rises up, so the liquid is distributed about evenly across the thermometer's tube.
