Water is a compound. A compound is made up of two or more elements. In the case of water, or H2O, there are 2 hydrogen atoms present and 1 oxygen atom. I hope this helps you on your assignment. Good luck!
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: Option (d) is the correct answer.
Explanation:
The given equations as as follows.
(slow)
Therefore, overall reaction equation will be as follows.
So, cancelling the spectator ions then the equation will be as follows.
As, it is known that slow step of a reaction is the rate determining step. Therefore, rate law for the slow step will be as follows.
Rate law =
Hence, the reaction is first order with respect to and it is also first order reaction with respect to .
Also, acts as a catalyst in the reaction.
Thus, we can conclude that the incorrect statement is is a catalyst.
Answer:
If you give me brainliest I will answer your question. I've been told i would get brainliest about 10 times now and every single time I answer their question no brainliest. If you mark me brainliest, I will answer this for you
Explanation:
If molarity is in mol/dm3
2HCL+Ca(OH)2=CaCl2+2H2O
Moles of ca(oh)2 = 98/1000 x 0.250
= 0.0245 moles
moles of hcl = 0.049 As the 1 is to 2 ratio among them
moles = molarity x volume
0.049 = molarity x 24/1000
molarity=2.042 mol/dm3
ANSWER IS 2.042 mol/dm3
