Answer:
Explanation: k =10^3, m =10^-3
2.8 Kg = 2.8 *10^3 g
To conver kg to mg you need to
=2.8* 10^3 *10^-3* 10^3
=2.8 * 10^6 *10^-3
= 2.8 * 10^6 mg
Answer:
D. Ten apples cost $9
Explanation:
C, the cost in dollars of buying apples is a function of the number (n) of apples bought
C (10) = $9 implies that the cost of buying 10 apples is $9
It is about 30 % of all tobacco..
Answer: The equilibrium constant is
Explanation:
Initial concentration of = 0.095 M
The given balanced equilibrium reaction is,
Initial conc. 0.095 M 0 M
At eqm. conc. (0.095-x) M (2x) M
Given : 2x = 0.0055
x = 0.00275
The expression for equilibrium constant for this reaction will be,
Now put all the given values in this expression, we get :
Thus the equilibrium constant is
