If I react 6 units of AB with 10 units of CD in the equation below, what is the limiting reactant? 3AB + 4CD --> 2AD + 6CB
irga5000 [103]

If 6 units of AB were reacted with 10 units of CD in the described equation, the limiting reactant would AB

<h3>Limiting reactants</h3>

They are reactants that determine how far a reaction can go in terms of yield.

From the equation: 3AB + 4CD --> 2AD + 6CB

The mole ratio of AB to CD is 3:4

Thus, 6 units of AB will require 8 units of CD.

But 10 units of CD were reacted with only 6 units of AB. This means that CD is in excess by 2 units while AB will limit the yield of the reaction.

The volume of a gas is 0.668 L at 66.8°C. At what Celsius temperature will the gas
tekilochka [14]

Answer:

206 c

Explanation:

Use the Charles' Law because you have the volume and temperature given.

V1 / T1 = V2 / T2

Let's list the given:

V1 = 0.668 L

V2 = 0.942 L

T1 = 66.8 C (339.8K)

Convert all Celsius temps to Kelvin. Just add 273.

Asked: T2

Derive the formula for T2.

T2 = V2T1 / V1

    = (0.942)(339.8) / 0.668

    = 479K

Since the temp should be in C, just subtract 273 from 479K.

The answer is 206 C.
