Answer:
a. Does not obey Conservation of Mass law
Explanation:
An example of an <em>unbalanced chemical equation</em> is:
- H₂SO₄ + NaOH → Na₂SO₄ + H₂O
As you can see, there are two Na atoms on the right side of the equation, while only one on the left side, causing the masses on both sides of the equation to not be equal. In other words, <em>not fulfilling the Conservation of Mass law</em>.
<em>Compare with the correctly balanced equation</em>:
- H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
Now both sides of the equation possess the same number of atoms for each element.

Explanation:
We are given with the composition of the air inside a breathing apparatus which is
<span>78% N2
21% O2
The total pressure at a given depth is 500 kPa
The partial pressure of oxygen is
500 kPa (0.21) = 105 kPa</span>
The geometry of a complex is determined by the number of ligands that surround the central atom/ion. There are four ligands in the complex. The coordination number of the complex is 4. The oxidation number of Rh is zero. The preferred geometrical shape of this complex is square planar.
Complexes are formed when Lewis bases called ligands become attached to a central metal atom or ion. The coordination number of the complex refers to the number of ligands that surround the central metal atom/ion.
In this case, four ligands surround the central Rhodium atom in a zero oxidation state.
Since we were told that the compound exhibits cis/trans isomerism then it can not have a tetrahedral geometry. It must have a square planar geometry as tetrahedral complexes do not exhibit cis/trans isomerism.
The image of the cis- and trans- geometrical isomers of the compound is attached to this answer.

Answer:
- The speed of the wave in the rope is 2 m/s
Explanation:
1. <u>Data</u>:
a) ν = 4 Hz
b) λ = 0.5 m
c) s = ?
2. <u>Physical principles and formula</u>:
The propagation of waves in a rope is a classical example of <em>transverse waves</em>: the pulse is inflected in the <em>vertical</em> direction and the wave travels in the <em>horizontal</em> direction, i.e. the pulse or vibration is perpendicular to the motion of the media particles.
The equation that relates <em>speed (s), wavelength (λ), frequency (ν) </em>is:
- wavelength = speed × period
- wavelenfth = speed / frequency
- meter = (meter/second) / second⁻¹
3. <u>Solution</u>:
