Using ideal gas equation, PV = nRT, and since there is no volume change and amount change, the equation is now P = kT, where k =nR/V. Temperature must be in kelvin From the given, k = (0.82)/ (21 + 273) = 2.78 x 10^-3 Substituting T = -3.5+273, P = 0.75 atm

A particular solution of NaOH has hydronium concentration of 4x10-9 M. what is the solution’s pH?
bearhunter [10]

Answer:

The pH of the solution is 8, 40-

Explanation:

The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and greater than 7 to 14 basic. It is calculated as

pH = -log (H30+)

pH= -log (4x10-9M)

<em>pH=8,40</em>

What is refraction? * Bending of light<br> Reflection of light
sdas [7]
Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light. Hope this helps!

In a well-constructed response explain the differences and similarities between Natural Selection and Selective Breeding
lakkis [162]
Natural selection and selective breeding can cause both animal and plant changes. The distinction between the two is that natural selection occurs without human intervention, while selective breeding occurs only when humans interfere. As a result, selective breeding is also known as artificial selection.

What is the precent yield if the actual yield is 25g and 100g should have formed?
11Alexandr11 [23.1K]

Answer:

Percent yield is 25%

Explanation:

Information given is

Actual yield is 25 g

But the yield should be 100 g

The percent yield is defined as the ratio of the actual yield and the predicted yield it means that out of the predicted yield what percentage of the actual yield is obtained

∴ Percent yield = (Actual yield ÷ Predicted yield) ×  100

In case of the given problem the percent yield will be

(25÷100) × 100 = 25%

∴ Percent yield = 25%
