Answer:Increase the enzyme concentration
Explanation:
If the enzyme is saturated, it simply means that all the enzyme molecules present has been bound to substrates.
Of course, there will still be more substrates left in the system since the enzyme is saturated. The reaction rate can now be increased by increasing the enzyme concentration so that more enzyme molecules can be bound to substrates.
To determine the expected pH of the resulting solution of the following substances, create a balanced chemical equation of their ionization in water:
HI
HI + H2O ---> H+ + I-
It completely dissociates into H+ and I-. Due to the presence of the Hydronium Ion, the solution is acidic.
KBr
KBr + H2O ----> HBr + KOH
The salt KBr is formed by a strong base and a weak acid, therefore, the solution it forms with water is basic.
LiOH
LiOH + H2O ----> Li+ + OH-
It dissociates completely in water, turns into Li+ and OH-. Due to the presence of Hydroxide Ion, the solution becomes basic.
3.9 grams CaCO3
The mass of 2.0 L of water with a density of 1.00 g/ml is 2000 grams.And 1 ppm of that is 2000 / 1000000 = 0.002 grams. So just multiply by the ppm of CaCO3, giving 0.002 g * 1.95x10^3 = 3.90 grams.
Since the least accurate datum we have is 2 significant figures, the result should be rounded to 2 significant figures, giving 3.9 grams.
Isn't always true could be false. You should try this I'm trying to help.
Hydrogen only has 1 electron so not A.
Barium has 2 valence electrons so answers B!
