Answer:
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
k= rate constant
m = order with respect to A
n = order with respect to B
Total order = m+n
is ideal gas equation
is vant hoff equation.
is equilibrium constant.
Explanation:
We know that Ionic radius increases on going downwards in any group. In group 15, the last elements Sb and Bi have ionic radii lesser than the rest of its elements i.e N,P and As.
This is due to the fact that Sb and Bi have completely filled d and f sub-shells which have least shielding effect.
Thus, they do not guard the valence electrons to a greater extent due to which the valence electrons feel almost whole nuclear charge.
This, results into attraction of valence electrons towards nucleus and hence size decreases.
Answer:
Explanation:
1st) one are homogenous because the have the same kind of force 9 London force ) all the hydrocarbons are nonpolar and have a London force between their molecules
so pentane dissolve in hexane (like dissolves like )
2nd ) CBr4 has a tetrahedral shape its a nonpolar compound (London bond )
but the water is polar molecules has a ( hydrogen bond ) its molecular shape (bent shape) . Both do not dissolve in each other because they have a different kinds of bond so they are <u>not a homogenous solution </u>.
3rd) its a homogenous because the water can dissolve the ionic bonds between the Li ( cation ) and (NO3 -1 anion ).
4th ) here we can say alcohol can dissolve in a little amount why ?
- pentane has a London force bond
- Alcohol has two different parts first part has OH making hydrogen bond which cant dissolve in the pentane different kinds of bonds ,and the other part -CH3 has a London force bond that can dissolves easily in the pentane
- so one part dissolves but the other part can't dissolve so the two compound are slightly dissolves in each other that which mean its <u>not a homogenous solution </u>
Answer:
Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).

Answer:
The answer to your question is Energy = 36.036 J
Explanation:
Data
mass of Copper = 39 g
ΔT = 24°C
C = 0.0385 J/g°C
Q = ?
To calculate the energy absorbed just substitute the values given in the specific heat formula.
Q = mCΔT
Substitution
Q = (39)(0.0385)(24)
Simplification
Q = 36.036 J
