Answer:
The property that determines whether an acid is weak or strong is its ability to dissociate and form ions.
Explanation:
For the first one.. the Reactant side is Zn+2HCl produces Zncl2 and H2... and it is balanced too
See here question has answer in itself
The structural isomerism starts always from but word root .
So butane has one and most among all as rest three have none .
The two isomers are
No it’s a decomposition reaction
Explanation:
Hint- look where the arrow is
If there is 1 product with an arrow next to it, then it is a decomposition reaction
This shows a product decomposing (breaking down) into 2 elements, which is a decomposition reaction
The "Ideal Gas Law Equations" is

P= Pressure (in Pascals)
V=Volume (in Liters)
n=amount, or <u>
n</u>umber (in moles)
R= 8.3145

or

T= Temperature (In Kelvin)

Plug into the equation and you're good!



If your teacher cares about sig figs,
2 sig figs (significant figures)

For other units of pressure,
1 atm = 760 mmHG = 760 Torr = 101326 Pa = 1.01325 bar<u />
