If I add 25mL of water to 125 mL of 0.25 M NaOH solution, what will the molarity of the diluted solution be?

Answers

Answer 1
Answer:

Answer:

0.208333 M

Explanation:

M2=M1V1/V2=(0.25 M)(125mL)/(125mL+25 mL)= 0.208333 M

What determines the strength of an Arrhenius base?

Answers

The force is measured by the degree of dissociation that relates the number of unit formulas that dissociated themselves with those that were dissolved in the beginning.

What is the reason water is a liquid at normal earth conditions when it should be a gas

Answers

Actually, from the phase diagram, water should exist as liquid at normal conditions. At a pressure of 1.0 atm and 25 degrees Celsius, water exist as a liquid not a gas. Only when the temperature reaches 100 and more, it exist as gas.

Arrange the following measurements, in seconds, from the greatest bias to the least bias. 6.63 ± 0.01 s, 6.6 ± 0.1 s, 6.52 ± 0.05 s, 6.4 ± 0.5 s

Answers

I understand here "bias" to be the uncertainty of measurements. So the order will be the following:

6.4 ± 0.5 s
6.6 ± 0.1 s,
6.63 ± 0.01 s,
6.52 ± 0.05 s,

(notice how the second number, the one behind the symbol ± gets smaller, as the bias gets smaller). 



Which materials typically make up the a horizon in soil?

Answers

The A horizon is a surface horizon that largely consists of minerals (sandsilt, and clay) and with appreciable amounts of organic matter. This horizon is predominantly the surface layer of many soils in grasslands and agricultural lands.These materials typically accumulate through a process termed illuviation, wherein the materials gradually wash in from the overlying.
