Describe how visible spectroscopy could be used to determine the order of a reaction in which a single colorless reactant produc
d1i1m1o1n [39]

Answer:

Explanation:

In a reaction, where, one of the reactant produces a colored product, visible spectroscopy can be used to determined the order of a reaction, the change in concentration of the reactant which forms the colored product is determined by absorbance measurement over time. The data for the concentration and time are plotted on the y and x axis and If we get a straight line it is a zero-order reaction. If instead, a plot of ln[concentration] versus time gives a straight line, it is a first order reaction. However, If 1/concentration versus time gives a straight line, it is a second order reaction kinetics. The other reactants may be changed while keeping this reactant as constant and change on rate of the reaction is observed to see If the other reactant affects the reaction or not.

Is wine a homogenous mixure
Fiesta28 [93]

Tap water and rain water are both homogeneous, even though they may have different levels of dissolved minerals and gases. A bottle of alcohol is a man-made homogeneous mixture, from a fine Italian wine to a glass of Scotch whisky. In the human body, blood plasma is an example of a homogeneous mixture.

Covert 1.57 x 10^14 nm= ___m
LekaFEV [45]

Answer:

1.57 x 10⁷m

Explanation:

Given quantity is;

          1.57 x 10¹⁴nm

Now;

            1 nm  = 10⁻⁹

So, let us convert this given quantity;

         1 nm          =             10⁻⁹

  1.57 x 10¹⁴nm  will give 1.57 x 10¹⁴ x 10⁻⁹  = 1.57 x 10⁷m

How many representative particles are in one mole of CO2? PLEASE ANSWER ALMOST DUE
igor_vitrenko [27]

Answer:

I hope this helps, sorry if it doesnt. Not really good with chemistry, hope you have a great day/night :}

Explanation:

A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance.

12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
