4. Sublimation and deposition point
Chemistry

Answer:

Freezing and boiling point

Explanation:

A liquid form of any substance is an intermediate form between the solid form and the gaseous form.

Decreasing the temperature of liquid water according to the phase diagram of H_2O would freeze it and we would have a phase change from liquid to solid (ice) at the freezing point of water.

Similarly, heating water to its boiling point would evaporate water and we would have a phase change from liquid to gas (water vapor).

Therefore, liquid water exists between its freezing and boiling point.

laiz [17]

A uniform cube is subjected to volume expansion. Each side gets decreased by 1%, then the bulk strain is 0.03.

<h3>What is Volume?</h3>

Volume is the space occupied by a three-dimensional object.

<h3 />

Given that, the side cube is l, then

volume V = l³

\dfrac{\Delta V}{V} = \dfrac{3D1}{1}

For change in volume

% Change in volume = 3× % change in length

= 3 × 1%

Hence, bulk strain = 0.03.



Thus, the bulk strain is 0.03.

Choose the molecule(s) that will only show two signals, with an integration ratio of 2:3, in their 1H NMR spectrum.
mrs_skeptik [129]

The question is missing the molecules in which the integration ratio of 2:3 will be observed. The complete question is given in the attachment.

Answer:

Molecule (a), (c), and (f) will show two peaks with the integration ratio of 2:3 in their 1H NMR spectrum

Explanation:

In the 1H NMR spectrum, the peak area is dependent on the number of hydrogen in a specific chemical environment. Hence, the ratio of the integration of these signals provides us with the relative number of hydrogen in two peaks. This rationale is used for the assignment of molecules that will give 2:3 integration ratio in the given problem.

  • Molecule (a) have two CH₂ and three CH₃ groups. Hence, it will give two peaks and their integration ratio becomes 2:3 (Answer)
  • Molecule (b) contains three chemical environments for its hydrogen atoms
  • Molecule (c) have a single CH₂ and CH₃ group giving integration ratio of 2:3 (Answer)
  • Molecule (d) will give two peaks but their ratio will be 1:3 because of two hydrogens of CH₂ and six hydrogens from two CH₃ groups
  • Molecule (e) have three CH and three CH₃ groups, so their ratio will become 1:3
  • Molecule (f) contains four CH and two CH₃ groups, giving two peaks. So, the integration ratio of their peaks is 2:3 (Answer)
  • Molecules
  • (g)
  • and
  • (h)
  • both have two CH and two CH₃ groups giving two peaks with the integration ratio of 1:3

___________ minerals are dark-colored because they contain _____________. a. Mafic; iron and/or magnesium b. Felsic; iron and/or
Likurg_2 [28]

Answer:

A. Mafic; iron and/or magnesium

Explanation:

Let's find the answer by naming some minerals and their chemistry.

Mafic minerals are dark-colored whereas felsic minerals are light-colored, thats way mafic rocks are dark-colored because they are mainly composed by mafic minerals and the other way around for felsic rocks.

But remember that mafic minerals as amphiboles, pyroxenes or biotites, involve in their chemical structure iron and/or magnesium. Although calcium and sodium can be incorporated in amphiboles and clinopyroxenes, they are not involved in orthopyroxenes and biotites. On the other hand, although potassium is involved in biotite and in some extent in amphiboles, this element is not involved in pyroxenes.

So in conclusion, mafic minerals are usually dark-colored because they involve iron and/or magnesium in their chemical structures.
