I NEED HELP FAST, BRAINLIEST! :) Why is water a good choice of fluid in a heat exchanger?

Chemistry

Answer:

Water is a good heat transfer fluid as it has a high thermal capacity and low viscosity. It is cheaper to use because its application in direct steam generation saves cost in the heat exchanger. However, it is unstable and difficult to manage at high temperatures.

Explanation:

hope this helps

An unknown triprotic acid (H3A) is titrated with NaOH. After the titration Ka1 is determined to be 0.0013 and Ka2 is determined
e-lub [12.9K]

Answer:

6.68 X 10^-11

Explanation:

From the second Ka, you can calculate pKa = -log (Ka2) = 6.187

The pH at the second equivalence point (8.181) will be the average of pKa2  and pKa3. So,

8.181 = (6.187 + pKa3) / 2

Solving gives pKa3 = 10.175, and Ka3 = 10^-pKa3 = 6.68 X 10^-11

What does it mean for a strong base to be in equilibrium?
prisoha [69]

The position of equilibrium lies far to the right, with products being favoured. Hence, option A is correct.

<h3>What is equilibrium?</h3>

Chemical equilibrium is a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs.

A very high value of K indicates that at equilibrium most of the reactants are converted into products.

The equilibrium constant K is the ratio of the concentrations of products to the concentrations of reactants raised to appropriate stoichiometric coefficients.

When the value of the equilibrium constant is very high, the concentration of products is much higher than the concentration of reactants.

This means that most of the reactants are converted into products and the position of equilibrium lies far to the right, with products being favoured.

Hence, option A is correct.

Two students (X and Y) measured the diameter of a gold coin four
Eddi Din [679]

Explanation:

To solve this problem, we need to understand the concept of precision and accuracy.

Through this understanding we apply to solve this problem.

  • Precision is the ability to reproduce the same set of values in an experiment.
  • Accuracy is the nearness or closeness of the measured value to the true value.

For example; if the true value is 28.0mm and the following readings were made:

        A  =  24.0mm, 24.0mm, 24.3mm, 23.9mm  This is a precise measurement but not accurate.

      B  =  27.9mm, 28.0mm, 28.1mm:  This is an accurate measurement because it is close to the true value.
