As a reaction proceeds, the ratio between the rate of consumption of reactant and the rate of formation of product:
wariber [46]

Answer:

Depends on the reaction.

Explanation:

Hello,

In this case, the answer is depends on the reaction since the ratios between the rates of both consumption and formation depend upon the stoichiometric coefficients in the chemical reaction. For instance, for the reaction:

A -> 2B

The relationship is:

\frac{1}{-1}r_A =\frac{1}{2} r_B

Therefore, we can see that the rate of consumption of A half the rate of formation of B, but is we consider the following chemical reaction:

2A -> B

The relationship is:

\frac{1}{-2}r_A =\frac{1}{1} r_B

Therefore we can see that the rate of consumption of A doubles the rate of consumption of B.

Best regards.

In the reaction 2H2O (l) + 2Cl– (aq) → H2 (g) + Cl2 (g) + 2OH– (aq), which substance is oxidized?
pashok25 [27]

F. None of the above [Cl^(-) is oxidized]

<em>No Cl atoms are available</em> to be oxidized, only Cl^(-)ions

2Cl^(-) → Cl_2 + 2e^(-)

The substance that <em>loses electrons</em> is oxidized.

Remember <em>OIL</em> RIG (<em>O</em>xidation<em> I</em>s <em>L</em>oss of electrons) and

<em>LEO</em> the lion says GER (<em>L</em>oss of Electrons is <em>O</em>xidation).

Calculate the percentage of sulfur in CuSO4. Please show your work.
777dan777 [17]
%= total atomic mass of element/formula mass of the compoundX100
atomic mass(Ar) of sulfur- 32
Ar of Cu- 64
Ar of O-16
64+32+(16x4)= 160
32/160=0.2
0.2x100=20
20%

The correct number of significant figures in the number 1.250100 is:
Elenna [48]
The correct number of sig figs for this number is 7 because all whole numbers count and all zeros after the decimal counts too. So, all the numbers count, which is 7.
