Chemical properties are all those properties that are shown when the chemical is a part of a reaction or is changed in any way. Unlike physical properties, they affect the composition of the chemical and the way it behaves, while physical does not change the chemical itself. Such properties are toxicity, flammability, reaction with other elements, stability, and many more.
Answer:
7
Explanation:
Given that the total charge is given by;
C =nq
Where;
n = number of charges
q = quantity of charge
Where the total amount of charge is -1.12 x 10-18 C and the magnitude of each charge is -1.602 x 10-19 C
Then the number of electrons is obtained from;
n = -1.12 x 10-18 C/ -1.602 x 10-19 C
n = 7
Answer:
A. Butane
Explanation:
"Butane is a gas above -0.5°C, but when slightly pressurized, forms a liquid. In this form, it is used in cigarette lighters and lighter sticks."
Hope this helps!

Answer:
Explanation:
We shall apply Arrhenius equation which is given below .
![ln\frac{k_2}{k_1} = \frac{E_a}{R} [\frac{1}{T_1} -\frac{1}{T_2} ]](https://tex.z-dn.net/?f=ln%5Cfrac%7Bk_2%7D%7Bk_1%7D%20%3D%20%5Cfrac%7BE_a%7D%7BR%7D%20%5B%5Cfrac%7B1%7D%7BT_1%7D%20-%5Cfrac%7B1%7D%7BT_2%7D%20%5D)
K₂ and K₁ are rate constant at temperature T₂ and T₁ , Ea is activation energy .
Putting the given values
![ln\frac{5.9}{1} = \frac{39500}{8.3} [\frac{1}{298} -\frac{1}{T_2} ]](https://tex.z-dn.net/?f=ln%5Cfrac%7B5.9%7D%7B1%7D%20%3D%20%5Cfrac%7B39500%7D%7B8.3%7D%20%5B%5Cfrac%7B1%7D%7B298%7D%20-%5Cfrac%7B1%7D%7BT_2%7D%20%5D)
![.000373= [\frac{1}{298} -\frac{1}{T_2} ]](https://tex.z-dn.net/?f=.000373%3D%20%5B%5Cfrac%7B1%7D%7B298%7D%20-%5Cfrac%7B1%7D%7BT_2%7D%20%5D)
T₂ = 335.27 K
= 62.27 °C
