Answer:
Explanation:
Brittleness : The ability of an object to break apart or shatter easily
Ductility: The ability of a substance to be stretched out into a long wire-like shape.
Lustre: the ability of an object to reflect light.
Malleability is a substance's ability to deform under pressure
The melting point of ice is 0°C. The melting point of a solid is the same as the freezing point of the liquid
Solubility is the relative ability of a solute to dissolve into a solvent.
solid: Has a definite shape and volume.
liquid: Has a definite volume, but take the shape of the container.
gas: Has no definite shape or volume. change of state
The resistance of a liquid to flowing is its viscosity.
Let me Know if i missed somethin!!! :) Hope this Helped!!!
Answer:
It will have no effect
Explanation:
The loss of tin oxide to evaporation will have no effect on the empirical formula of a compound.
The empirical formula of any compound is the simplest formula of that compound by which the combining atoms can be represented.
This formula is not affect by physical changes.
According to the law of constant composition "all pure samples of the same compound have the same element in the same proportion by mass".
Regardless of the mass loss or gain of any tin oxide compound, it will have the same empirical and molecular formula. The atoms are still combining in the ratio to give the product.
Answer:
Okay, Left top= waning gibbous
left second= new moon
left third= third quarter
left fourth= waxing crescent
right top= Waning crescent
right second= first quarter
right third= full moon
right fourth= Waxing gibbous
hope you do good :)
How many moles of oxygen atoms are present in 5
moles of Mg3(PO4)2
All you have to do is to create
a ratio between the molecule and the oxygen atom.
5 moles of Mg3(PO4)2 (4x2 moles
O/1 mole Mg3(PO4)2) = 40 moles of oxygen
