If you place a dialysis tubing permeable only to water filled with 10% sucrose solution into a beaker filled with a 30% solution of sucrose, you would expect for the water molecules from the 10% solution to pass through the membrane and dilute the 30% solution until the concentration in both solutions are equal. Thus, in equilibrium.
<u>1) determine which formula you are going to use.</u>
<u>2) list your information.</u>
P = 101.325 kPa
V = 3.57 L
n = ?
R = 8.314
T = 273.15 K
<u>3) rearrange your formula</u>
<u>4) solve.</u>
<em>n = 0.159 mol NH₃</em>
Answer:
<h3>The International Union of Pure and Applied Chemistry (IUPAC) defines alkanes as "acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2, and therefore consisting entirely of hydrogen atoms and saturated carbon atoms". ... The number of carbon atoms may be considered as the size of the alkane.</h3>
Answer:
The lock and key model is used to explain how enzymes work.
Explanation:
An enzyme is a protein that functions as a biological catalyst . Enzymes are folded into complex shapes that allow smaller molecules to fit into them. The place where these molecules fit is called the active site.
The lock and key model was given by Emil Fischer in 1984 . According to this model the active sites of the enzymes have a specific geometric shapes wherein the substrate molecules fit in just like a key in a particular lock.
The lock and key model of an enzyme action is based upon structural complimentarity between the substrate molecule and the enzyme active site . Thus specific enzyme molecules will interact with specific substrate molecules only .
This specific action of an enzyme with a single substrate can be explained using lock and key analogy . In this analogy the lock is the enzyme and the key is the substrate . Only correctly sized key ( substrate ) fits into the key hole ( active site ) of the lock ( enzyme )
Answer:
CH₄(g) + 2O₂(g) ---> 1CO₂(g) + 2H₂O(g)
Explanation:
any combustion of a hydrocarbon equation is in form:
CₓHₐ(g) + BO₂(g) ---> YCO₂(g) + ZH₂O(g), where x,a,b,y,z are all whole number positive integers
there will be 1 CO₂ to 2 H₂O, since there is 1 C to 4 H in CH₄; it is not 1:4 since 2 H is needed in H₂O
CH₄(g) + _O₂(g) ---> 1CO₂ + 2H₂O
there is 4 total O on products side, which can make 2O₂
CH₄(g) + 2O₂(g) ---> 1CO₂(g) + 2H₂O(g)
