Answer:
A safety pin
Explanation:
Rubber, plastic and food are all non-metals, meaning they are poor conductors of heat and electricity. However, safety pins are made up of steel - a metal - making them good conductors.
Density equal mass/volume
so you would have 84.96/4.35= 19.5310345
i hope i remembered this right
Answer:
identical atom in which an electron moves from the first to the third shell.
Atoms may occupy different energy states. The energy states are discrete, i.e. they occur at specific values only. Therefore an atom can only move to a new energy level if it absorbs or emits an amount of energy that exactly corresponds to the difference between two energy levels.
The lowest possible energy level that the atom can occupy is called the ground state. This is the energy state that would be considered normal for the atom.
An excited state is an energy level of an atom, ion, or molecule in which an electron is at a higher energy level than its ground state.
An electron is normally in its ground state, the lowest energy state available. After absorbing energy, it may jump from the ground state to a higher energy level, called an excited state.
The number of atoms that are in 9.008 moles of carbon is
5.423 x 10^24 atoms
<u><em>calculation</em></u>
The number of atoms is calculated using the Avogadro's constant
That is According to Avogadro's 1 moles = 6.02 x 10^23 atoms
9.008 moles= ? atoms
by cross multiplication
= [(9.008 moles x 6.02 x 10^23 atoms) / 1 mole] = 5.423 x10^24 atoms
Lol yeah that’s what I’m doing I just want you know I got a lot of you guys to go and you don’t get
