A sealed, flexible container holds 92. 5 mL of xenon gas at 15. 0 C. Find the temperature needed (in degrees Celsius) to result in the container doubling its volume at a constant pressure

Answers

Answer 1

The formula for Charles' law is `(V1/T1) = (V2/T2)`. The gas is in a sealed flexible container, meaning the pressure of the gas is constant. Here's how to use Charles's law to solve the question:

First, determine the initial temperature (T1) and volume (V1) of the xenon gas. V1 = 92.5mL (given)T1 = 15°C + 273.15 = 288.15 K (convert to Kelvin)The problem states that the container's volume must double. Thus, the final volume (V2) will be two times the initial volume. V2 = 2 x V1 = 2 x 92.5mL = 185 mLUsing Charles's law, we can solve for T2:(V1/T1) = (V2/T2)(92.5mL / 288.15 K) = (185 mL / T2)Rearrange the equation to solve for T2:(92.5mL / 288.15 K) x T2 = 185 mL T2 = (185 mL x 288.15 K) / 92.5mL T2 = 573.18 KConvert the final temperature from Kelvin back to Celsius:T2 = 573.18 K - 273.15 T2 = 300.03°CChecking the answer:When the temperature of a gas at a constant pressure doubles, the volume doubles as well. Therefore, this answer is reasonable.

Explanation:

84.9 g of solid iron reacts with oxygen gas forming iron(III) oxide. How many moles of oxygen will react

Answers

Answer:

1.14 moles of oxygen will react

Explanation:

The balanced equation of reaction between iron and oxygen is  

4 Fe + 3 O₂  → 2 Fe₂O₃

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

Fe: 4 molesO₂: 3 molesFe₂O₃: 2 moles

The molar mass of iron being Fe 55.85 g/mole, then the following amount of mass reacts by stoichiometry: 4 moles* 55.85 g/mole=223.4 g

You can apply the following rule of three: if by stoichiometry 223.4 grams of Fe react with 3 moles of O₂, 84.9 grams of Fe react with how many moles of O₂?

[tex]moles of O_{2} =\frac{84.9 grams of Fe*3 moles ofO_{2} }{223.4 grams of Fe}[/tex]

moles of O₂= 1.14 moles

Answers

Answer:

1) oxidation

2) Reduction

3) Oxidation

4) Reduction

5) Reduction

6) Reduction

7) Oxidation

8) Reduction

Explanation:

Oxidation is said to have taken place when there is a positive change in the oxidation number while reduction is said to have taken place when there is a decrease in the oxidation number.

The change from CH3CHO to CH3CH2OH represents on oxidation reaction.

The change from CH3OH to CH4 is a reduction because the oxidation number of carbon changes from +2 to -4.

The change from N2H4to N2 is an oxidation because the oxidation number of nitrogen increases from -2 to 0.

The gain in electrons is a reduction because the gain of electron leads to a decrease in oxidation number.

The change from NO- 2 to NH3 is a reduction because the oxidation number of nitrogen changes from +4 to -3.

The change from NAD+ to NADH is a reduction since NAD+ is the oxidized form of the enzyme while NADH is the reduced form of the enzyme.

The change from CH4 to Co2 is an oxidation because the oxidation number of carbon changes from -4 to + 4.

The change from Ag+ to Ag is a reduction because it involves the gain of one electron and a consequent decrease in oxidation number.

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.

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

C.

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 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.
