The device shows the relative humidity at 22°

sergeinik [125]

The relative humidity shows us saturation of water in air. Since it is 58% and not 100% we have to scale density that we were given when humidity is 100%.

At 100% humidity, density is 20grams/cubic meter

at 58% it will be:
0.58 * 20 = 11.6 g/m^3

Since the question is to find density, the answer cannot be in %.

Answer is 11.6 g/m^3

The sulfur atom of sulfur dioxide is considered to be sp2-hybridized. The expected bond angle is 120°, but is actually slightly

Alja [10]

Answer: The bonds are intermediate between double and single bonds

Explanation:

A closer look at the diagram below shows that the bonds in sulphur IV oxide are intermediate between double and single bonds. Hence they do not have the exact bond angle of single bonds. This is why the bond angle is not exactly 120°. There are two resonance structures in the diagram that clearly show this point.

Answer:

3.6 × 10²⁴ atoms of O

Explanation:

Let's consider the molecular formula of silver nitrate: AgNO₃.

We can establish the following relations:

1 mol of AgNO₃ has 6.02 × 10²³ molecules of AgNO₃ (Avogadro's number).
1 molecule of AgNO₃ has 3 atoms of oxygen.

The atoms of oxygen in 2.0 moles of silver nitrate are:

$2.0molAgNO_{3}.\frac{6.02\times10^{23}moleculeAgNO_{3} }{1molAgNO_{3}} .\frac{3atomO}{1moleculeAgNO_{3}} =3.6\times10^{24}atomO$

Several alkene compounds are given below. indicate if each compound can exist as stereoisomers.

Arturiano [62]

The compounds are missing. It will be helpful instead if you know what are stereoisomers. <span>Two molecules are described as stereoisomers of each other if they are made of the same </span>atoms<span>, connected in the same sequence, but the atoms are positioned differently in space in which the difference between two stereoisomers can only be seen when the three dimensional arrangement of the molecules is shown.</span>
