e. Positive ΔS

Answers

C. ) Negative Delta G is the answer that describes a spontaneous reaction

The answer is D
For Delta G the negative number is always spontaneous because it is less than 0

Which statement explains why a molecule of CH4 is nonpolar?(1) The bonds between the atoms in a CH4 molecule are polar.
(2) The bonds between the atoms in a CH4 molecule are ionic.
(3) The geometric shape of a CH4 molecule distributes the charges symmetrically.
(4) The geometric shape of a CH4 molecule distributes the charges asymmetrically.

Answers

The answer is the option (3) The geometric shape of a CH4 moleculedistributes the charges geometrically. the CH4 is a tetrahedral with theCarbon atom in the center and the four H atoms in the vertices of thetetrahedral. The C-H bond angles are all identical which makes themolecule perfectly symmetrical and so any dipolar moment will cancelmaking the molecule non polar.

The following statement explains why a molecule of $\text{CH}_4$ is nonpolar:

$\boxed{\left( 3 \right){\text{ The geometric shape of a C}}{{\text{H}}_4}{\text{ molecule distributes the charge symmetrically}}}$ .

Further explanation:

Covalent Bond

This type of bonding takes place when the bonded atoms mutually share electron pairs between them. It is also called the molecule bond. The chemical compounds formed as a result of this bond are called chemical compounds.

The polarity of any bond is primarily governed by two factors; electronegativity difference and symmetry. A bond is said to be polar if the bonded atoms have a considerable molecular bondelectronegativity difference between them. But if there is very small or no electronegativity difference between the bonded atoms, the resulting bond is nonpolar in nature.

Symmetry is another factor responsible for the polarity of the bond. The charge distribution is symmetrical in case symmetry is present in the molecule and as a result, the molecule is said to be nonpolar. But if there is asymmetry in the shape of the molecule, it will be polar in nature.

The electronegativity difference between carbon and hydrogen atoms in $\text{CH}_4$ molecule is very small or negligible so the bonds between the atoms in $\text{CH}_4$ are nonpolar in nature. But the hydrogen atoms are placed in symmetrical positions with respect to the central carbon atom, imparting symmetry to $\text{CH}_4$ molecule and therefore it is nonpolar (For structure, refer to the attached image).

Scientists use results from new experiments to

Answers

Answer:

The scientists use results from the new experiments to change the existing explanations of how nature functions. The world is changing continuously. There are outcomes, which have been obtained from the scientific studies performed earlier, which may no longer be accurate at present because of certain factors that may not have been discovered or present in those times. Other scientific findings may also be further acknowledged as true from the outcomes of the new experiments.

Final answer:

Scientists use results from new experiments to validate or refute existing theories and to explore new scientific territory. This is done by gathering and analyzing data from these experiments, ultimately leading to more informed and detailed theories.

Explanation:

Scientists use results from new experiments to both confirm existing theories and explore new territories of knowledge. Conducting an experiment helps scientists gather data and observations. These results then provide evidence that either supports or refutes a hypothesis, leading to more advanced and precise scientific theories. For example, when Albert Einstein proposed his theory of relativity, further experiments such as the Eddington experiment during a solar eclipse provided data evidence that supported his theory.

Which of the following is not a true statement? 0.2 moles O 2 = 6 g
0.75 moles H 2CO 3 = 47 g
3.42 moles CO = 84.0 g

Answers

Answer: 3.42 moles CO = 84.0g, is not true.

Explanation:

Moles is given by the formular; Mass / Molar Mass.

Therefore; 0.2 moles O2 = 6g is true when we multiply 32g x 0.2 = 6g approximately.

0.75 moles H2CO3 = 47g.

Molar formular for H2CO3 = 2 + 12 + 48 =62g.

If we multiply 62g (molar mass ) by 0.75moles, it gives us 47g approximately.

3.42 moles CO = 84g

molar mass of CO = 12 + 16 = 28g

Multiply 28g x 3.42 moles = 95.76g, which is not true.

Doesn't hydrogen have one energy level assuming that we only have one electron and not an ion?

Answers

It may have one occupied energy level at a time since it only has one electron, but overall it has several energy levels.

Yes, Hydrogen has one energy level, (an S sub-level that can fill up to two electrons).

The only other confusing thing about Hydrogen I can think of, is that you will almost never find it existing as a single Hydrogen, but as H2....
