Answer:
Explanation:
Glucose + ATP → glucose 6-phosphate + ADP The equilibrium constant, Keq, is 7.8 x 102.
In the living E. coli cells,
[ATP] = 7.9 mM;
[ADP] = 1.04 mM,
[glucose] = 2 mM,
[glucose 6-phosphate] = 1 mM.
Determine if the reaction is at equilibrium. If the reaction is not at equilibrium, determine which side the reaction favors in living E. coli cells.
The reaction is given as
Glucose + ATP → glucose 6-phosphate + ADP
Now reaction quotient for given equation above is
![q=\frac{[\text {glucose 6-phosphate}][ADP]}{[Glucose][ATP]}](https://tex.z-dn.net/?f=q%3D%5Cfrac%7B%5B%5Ctext%20%7Bglucose%206-phosphate%7D%5D%5BADP%5D%7D%7B%5BGlucose%5D%5BATP%5D%7D)
so,
⇒ following this criteria the reaction will go towards the right direction ( that is forward reaction is favorable until q = Keq
The moles of potassium that you would need to prepare 1200 g of 5% potassium sulfate solution is 1.538 moles
calculation
calculate the mass potassium using the below formula
%M/M = mass of the solute(potassium)/mass of the solvent (potassium sulfate solution)
let the mass of potassium be represented by Y
then convert % into fraction = 5/100
5/100 = Y/1200
cross multiplication
100y = 6000
divide both side by 100
Y= 60 g
moles of potassium =mass/molar mass
= 60/39=1.538

Answer is: directly up.
Neon (Ne) is noble gas with atomic number 10 and atomic mass around 20.
1) directly up is noble gas helium (He) with atomic mass around 4.
2) directly down is noble gas argon (Ar) with atomic mass around 40.
3) directly to the left is florine (F), with smaller atomic mass, but also from different group.
4) directly to the right there no elements, because noble gases are far right in 18. group of Periodic table.
Burning a piece of wood in fire can best be described as a CHEMICAL CHANGE BECAUSE THE ATOMS IN WOOD AND OXYGEN ARE REARRANGED.
In chemistry, there are two types of change, these are chemical and physical changes. In physical change, no new substance is formed and the process is usually reversible. In chemical change, chemical reactions usually occur, new substances are formed and the process is not reversible. Burning of wood in air is a chemical change because the atoms of the wood and the oxygen atoms react together to form new substances and the reaction is not reversible.
