Scientists need to explain not only what happened but also why things did not go as expected. Considering the experiment's outcomes, what results surprised you?

Answers

Answer 1

In the experiment, the results that surprised me were the unexpected reaction rates observed. It was anticipated that these substances would react at a much slower rate due to their chemical properties.

However, contrary to expectations, the reaction occurred rapidly, surpassing the predicted reaction rate.This unexpected outcome raises several questions and prompts further investigation. It challenges our understanding of the underlying mechanisms governing the reaction and demands an exploration of alternative factors that might have influenced the observed behavior.

Possible explanations could involve the presence of impurities or catalysts that enhanced the reaction, unforeseen environmental conditions, or variations in the concentration or physical state of the reactants. By delving into these factors, scientists can gain a deeper understanding of the complexities involved and refine existing theories to align with the observed results. Such surprises in experimental outcomes serve as valuable opportunities for scientific inquiry and the advancement of knowledge.

5.55 moles is the answer ....

Explanation:

if 18g H2O is equal to 1 mole then 100 g H2O is how much?

100/18 which is 5.55

Answer:

5.551

Explanation:

100.0g x 1mol H20/18.015g H20 = 5.551 moles of H20

The 18.015g is from the periodic table. H = 1.008x2 = 2.016g H2

0= 15.999

15.999 + 2.016= 18.015

How many atoms are in 1.22 moles of magnesium?

Answers

Answer:

7.34684 × 10^23 atoms

Explanation:

Well, one mole is basically

6.022 × 10^23 atoms. So 1.22 moles would be

6.022 × 10^23 ⋅ 1.22 atoms.

6.022 × 10^23 ⋅ 1.22 = 7.34684 × 10^23 atoms

The total number of atoms in 1.22 moles of magnesium is 7.34 × 10²³.

One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions).The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant.

Given:

1.22 moles of magnesium

[tex]1 \text{ mole}= 6.022*10^{23}\text{ atoms}\\\\1.22 \text{ moles}= 1.22*6.022*10^{23}\text{ atoms}\\\\1.22 \text{ moles}=7.34*10^{23}\text{ atoms}[/tex]

So, the total number of atoms in 1.22 moles of magnesium is 7.34 × 10²³.

What molecular geometry would be expected for BF3 and NH3?

Answers

Answer:

Boron trifluoride would have a trigonal planar geometry.Ammonia would have a trigonal pyramidal geometry.

Explanation:

There are three valence electrons in a boron atom.

In boron trifluoride, the central boron atom did not achieve an octet with eight valence electrons. Rather, that boron atom would be electron deficient with only six valence electrons.

Each of the three fluoride atoms would have shared one valence electron with that boron atom, with a total of three boron-fluorine single bonds. On the other hand, all three of the valence electrons of that boron atom would be involved in bonding. Hence, there would be no extra valence electrons to act as lone pairs on that boron atom.

Hence, the central boron atom would have three electron domains (one for each boron-fluorine bond) with none of the electron domains coming from lone pairs. By the VSEPR theory, the geometry of the molecule would be trigonal planar. All four atoms in this molecule would be in the same plane.

There are five valence electrons in a nitrogen atom.

In ammonia, the central nitrogen atom is indeed able to achieve an octet (with eight valence electrons in total.) Three of the five valence electrons of nitrogen would form a total of three hydrogen-nitrogen bonds. The other two valence electrons would form a lone pair.

Hence the central nitrogen atom would have four electron domains (one for each of the three hydrogen-nitrogen bond, and one for the lone pair.) Hence, by the VSEPR theory, the geometry of this molecule would be trigonal pyramidal.

How do you think the artist creates sculptures that vary in color and intensity?

Answers

Answer:

Light reflected off objects. Color has three main characteristics: hue (red, green, blue, etc.), value (how light or dark it is), and intensity (how bright or dull it is). Colors can be described as warm (red, yellow) or cool (blue, gray), depending on which end of the color spectrum they fall.

Christ Crowned / Honthorst

 

Christ Crowned with Thorns, Gerrit van Honthorst, about 1620

Value describes the brightness of color. Artists use color value to create different moods. Dark colors in a composition suggest a lack of light, as in a night or interior scene. Dark colors can often convey a sense of mystery or foreboding.

Light colors often describe a light source or light reflected within the composition. In this painting, the dark colors suggest a night or interior scene. The artist used light colors to describe the light created by the candle flame.

Annunciation / Bouts

 

The Annunciation, Dieric Bouts, 1450–1455

Intensity describes the purity or strength of a color. Bright colors are undiluted and are often associated with positive energy and heightened emotions. Dull colors have been diluted by mixing with other colors and create a sedate or serious mood. In this image the artist captured both the seriousness and the joy of the scene with the dull gray stone interior and the bright red drapery.

D.
The fossil record does not give enough evidence about the mammals to determine if there is a relationship between the three skulls.

If the point of the nail can be approximated as a circle with a radius 2.00×10^-3m What is the pressure in MPa exerted on the wall if a hammer strikes the nail with a force of 104 N

Answers

Answer:

8.28 MPa

Explanation:

From the question given above, the following data were obtained:

Radius (r) = 2×10¯³ m

Force applied (F) = 104 N

Pressure (P) =?

Next, we shall determine the area of the nail (i.e circle). This can be obtained as follow:

Radius (r) = 2×10¯³ m

Area (A) of circle =?

Pi (π) = 3.14

A = πr²

A = 3.14 × (2×10¯³)²

A = 3.14 × 4×10¯⁶

A = 1.256×10¯⁵ m²

Next, we shall determine the pressure. This can be obtained as follow:

Force applied (F) = 104 N

Area (A) = 1.256×10¯⁵ m²

Pressure (P) =?

P = F / A

P = 104 / 1.256×10¯⁵

P = 8280254.78 Nm¯²

Finally, we shall convert 8280254.78 Nm¯² to MPa. This can be obtained as follow:

1 Nm¯² = 1×10¯⁶ MPa

Therefore,

8280254.78 Nm¯² = 8280254.78 Nm¯² × 1×10¯⁶ MPa / 1 Nm¯²

8280254.78 Nm¯² = 8.28 MPa

Thus, the pressure exerted on the wall is 8.28 MPa
