Answer:
Value of 
is 0.090.
Explanation:
Initial molarity of 
= 
= 0.0700 M
Construct an ICE table corresponding to the combustion reaction of carbon to determine
I (M): - 0.0700 0
C (M): - -x +2x
E (M): - 0.0700-x 2x
So, ![K_{c}=\frac{[CO]^{2}}{[O_{2}]}](https://tex.z-dn.net/?f=K_%7Bc%7D%3D%5Cfrac%7B%5BCO%5D%5E%7B2%7D%7D%7B%5BO_%7B2%7D%5D%7D)
, where [CO] and ![[O_{2}]](https://tex.z-dn.net/?f=%5BO_%7B2%7D%5D)
represents equilibrium concentration of CO and respectively.
Here, ![[CO]=2x=0.060](https://tex.z-dn.net/?f=%5BCO%5D%3D2x%3D0.060)
⇒x = 0.030
So, = 0.0700-x = (0.0700-0.030) = 0.040
Hence, 
Answer: Mass
Explanation:
The moon and the Earth have a much higher gravitational pull than people because they weigh way more.
Answer:
Homogeneous means composed of parts of different kinds; having widely different elements or components.
Explanation:
Answer:
Fluorine is a <em>non-metal, fills its shell by gaining one electron </em>and<em> becomes a negatively charged ion.</em>
Explanation:
Fluorine have seven electrons in its outermost shell. This means that fluorine is located in Group 17(<em>Halogens</em>) in the Periodic Table. Note that halogens are non-metal elements. So fluorine is a non-metal.
Fluorine fills its shell by gaining one electron because it only needs one electron to achieve stable octet electron arrangement. ( it's easier to gain one electron than to lose all seven electrons in the outermost shell)
As fluorine atom gain one electron to achieve stable octet electron arrangement, its number of electrons becomes greater than its number of protons. So it becomes a negatively charged ion.
