Answer:
0.753M
Explanation:
Molecular formula of luminol is as follows: C8H7N3O2
Molecular formula of the luminol (C8H7N3O2) = 12(8) + 1(7) + 14(3) + 16(2)
= 96 + 7 + 42 + 32
= 177g/mol
mole of luminol = mass/molar mass
mole = 10 ÷ 177
mole = 0.0565 mol
Molarity can be calculated using the formula: Molarity = mol/volume (L)
Volume of water = 75.0 mL = 75/1000
= 0.075L
Molarity (M) = 0.0565 ÷ 0.075
The molarity of the stock solution = 0.753M
This is true because the water would have gravitational potential energy that is caused by the water being held back by the dam and the water wanting to flow down.
This can be converted into kinetic energy when given the chance to, such as having a turbine on the dam.
Hope this helps! :)
For bleaching a stain, there will be an identifiable odor and it will easily absorb colors and/or stains
Answer: The number 5 represents the coefficient, which is also equal to the number of moles of the formula unit above.
Answer:
B) hyperbolic curve; saturated with substrate
Explanation:
Enzymatic kinetics studies the speed of enzyme catalyzed reactions. These studies provide direct information about the mechanism of the catalytic reaction and the specificity of the enzyme. The speed of a reaction catalyzed by an enzyme can be measured with relative ease, since in many cases it is not necessary to purify or isolate the enzyme. The measurement is always carried out under the optimal conditions of pH, temperature, presence of cofactors, etc., and saturating substrate concentrations are used. Under these conditions, the reaction rate observed is the maximum speed (Vmax). The speed can be determined either by measuring the appearance of the products or the disappearance of the reagents.
Following the rate of appearance of product (or disappearance of the substrate) as a function of time, the so-called reaction progress curve is obtained, or simply, the reaction kinetics. This curve is represented by a hyperbolic curve
