Answer:
positive: proton
negative: electrons
no charge/nuetral: nuetron
Explanation:
no charge could be also described as nuetral.
The answer is C. No all cells have cell walls. Prokaryotes don’t have a nucleus or chloroplast. Leaving C to be correct
P: Good conductor of heat and electricity - R: the delocalized electrons are
free to move around the structure
P: High melting and boiling points - R: the bonds in metals are very strong
P: Ductile (can be stretched and squashed) - R: because the electrons are free to move, the atoms can slide over each other.
P: Malleable (can be hammered into shape) - R: the bonds in metal don't break easily
Gold alloys consist of most commonly Nickel!
Most commonly used in things like jewelry so it doesn't have such a heavy weight.
Answer:
molarity = moles of solution/liters of solution
molarity = 1 mole/2 liters
molarity = 0.5 M
molarity = 50 moles/200 kg
molarity = 0.25 M
