yes, and here is the reason: The Definition of a chemical property is a property in which a substance has a potential to change Identity under certain circumstances in that manner of chemical change.
Give atleast 2 point of difference .I am not able to mark out the difference .-Deliquescent - loses water vapour - gets lighter.
Hygroscopic - gains water vapour - gets heavier.-Lliverpool
An 8.442 g sample of Na2SO4 * xH2O is heated until all the water of hydration is driven off. The resulting anhydrous compound, Na2SO4 weighs 3.723 g. What is the formula of the hydrate?
Please explai
Methane has molecular weight = 16 ;
16 g of methane contains 6.023 X 10^23 molecules.
Mass of 9.85 X 10^19 molecules= 16 X {9.85 X 10^19/6.023 X 10^23} g
= 26.17 X 10^-4 g.-(9.85 x 10¹⁹) / (6.022 x
Arrange the following alkaline -earth-metaliodates in order of decreasing solubility in water:
Ba(IO3)2Be(IO3)2Ra(IO3)2Mg(IO3)2-group 2 iodates
the smaller the atom, the less soluble it is
Ra > Ba > M
Equal masses of the metals Na, Mg, Ca and Ag are added to separate samples of excess HCl (aq) which metal produces the greatest total volume of H2 (g) [hydrogen gas]
a) Na
b) Mg
c) Ca
d) Ag
and plea
I am trying to answer this question: a) If you were mixing 0.1 M NaOH (aq) and 0.1 M FeCl3 (aq) what would be the correct ration of drops to form the most precipitate?
b) Would the use of phenolphthal
For example, HCN is a weak acid, is there a way of knowing that just by looking at it?
I know that a weak acid is one that does not dissociate, or ionize completely.-Yes, there certainly is a way of
