Answer:
Tarnish,Striations,Shape,Color,Specific Gravity,Hardness,Ductility.
Explanation:
Ductility: Gold is usually very ductile in nature and will bend on pressure.Fool's Gold will break or resist the pressure.
Hardness: Gold(hardness scale 2.5) will most probably not scratch a copper surface (hardness of 3), but pyrite will very easily be able to do that. Even Gold will be scratched by copper pieces but copper can barely scratch other metals.
Color: Pyrite color is brass type. Gold has a little yellow to golden colour.
Tarnish :God can't be tarnished that easily whereas Pyrite can.
Answer:
try youre best to succsess
divide 5 hours 20 mins by 4,000
and ur answer is
320 mins/4000km
so
0.08
hope this helps
sorry if its wrong
Hello!
We have the following data:
m (mass) = 4.6 grams
MM (molar mass) of H2O
H = 2 * 1 = 2 amu
O = 1 * 16 = 16 amu
--------------------------
MM (molar mass) of H2O = 2 + 16 = 18 g/mol
Solving:
Establishing a relation with Avogadro's number (6.10²³) we have:
18 g of H2O --------------- 6.10²³ molecules
<span>4.6 g of H2O --------------- y molecules
