Whats the difference between hetergeneous and homogeneous?

1 answer:

4 0

In Homogeneous, "Homo" means same, so homogeneous means the same nature or kind.

Heterogeneous is the opposite. It means diverse.

A good way to remember is just think of homo as same. And the rest should come to you.

Hope this helps! :)

Answer: The value of $K_c$ for the net reaction is 13.94

Explanation:

The given chemical equations follows:

Equation 1: $A+2B\xrightarrow[]{K_1} 2C$

Equation 2: $2C\xrightarrow[]{K_2} D$

The net equation follows:

$D\xrightarrow[]{K_c} A+2B$

As, the net reaction is the result of the addition of first equation and the reverse of second equation. So, the equilibrium constant for the net reaction will be the multiplication of first equilibrium constant and the inverse of second equilibrium constant.

The value of equilibrium constant for net reaction is:

$K_c=K_1\times \frac{1}{K_2}$

We are given:

$K_1=2.37$

$K_2=0.170$

Putting values in above equation, we get:

$K_c=2.37\times \frac{1}{0.170}=13.94$

Hence, the value of $K_c$ for the net reaction is 13.94

Answer:

The correct option is: a. degrees Celsius

Explanation:

The anion gap is the difference in the cations and anions in plasma, serum or urine, calculated from medical lab test results. It can be calculated by measuring the concentration of the anions or cations, which are expressed in millimoles/litre (mmol/L) or milliequivalents/liter (mEq/L).

The temperature in this test is expressed in degrees Celsius (°C).
