for each type of geometry in the simulation, examine the resulting bond angles by clicking the show bond angles checkbox. based on your observations for each geometry, provide the bond angles at the indicated locations for the two-dimensional representations of the three-dimensional structures.

Answers

Answer 1

The bond angles in PCl5 are 90° and 180° respectively. The bond angle in NH4^+ is 109°.

Bond angles refer to the angle between two atoms bonded to the same central atom. Several factors such as electronegativity difference and presence or absence of lone pairs on the central atom all affect the bond angle.

For NH4^+, the indicated bond angle is 109° and the specie is tetrahedral. For the specie, SF6, the indicated bond angles are 90° and 180° respectively. For HCN, the indicated bond angle is 180°. For PCl5, the indicated bond angles are 90° and 180° respectively.

calculate the mass of butane needed to produce 64.1 g of carbon dioxide to three significant figures and appropriate units

Answers

Answer:

21.2 gm

Explanation:

calculate the mass of butane needed to produce 64.1 g of carbon dioxide to three significant figures and appropriate units

butane is the hydrocarbon C4H10  

in combustion, we react hydrocarbons with O2 to form CO2 and H2O

so

C4H10  + O2---------------->  CO2 + H2O

BALANCE

2C4H10 + 1302--------> 8CO2 + 10 H2O

the molar mass of CO2 is 12 + 16X2 = 44

64.1 gm of CO2 is

64.1/44 = 1.46 MOLES OF  CO2,

FOR EVERY 8 MOLES OF CO2 WE NEED 2 MOLES OF BUTANE  IT IS A

8:2 OR 4:1 RATIO.  THE MOLES OF C4H10 ARE 1/4 THE MOLES OF CO2

SO

THE MOLES OF C4H10 H10 ARE 1.46/4 =0.365 MOLES

THE MOLAR MASS OF BUTANE IS 58.12

0.365 MOLES OF C4H10 HAS A MASS OF 0.365 X 58.12 = 21.2 gm

A species acts as a(n) _____ agent if it gains electrons in a half-reaction. Conversely, it could potentially act as a(n) _____ agent if it loses electrons in a half-reaction.

Answers

A species acts as an oxidizing agent if it gains electrons in a half-reaction. Conversely, it could potentially act as a reducing agent if it loses electrons in a half-reaction.

REDOX REACTION:

Redox (oxidation-reduction) reaction is a type of reaction that involves the loss and gain of electrons by substances involved.

Redox reaction involves a reducing agent and an oxidizing agent. Oxidizing agent gains electrons in a redox reaction while reducing agent loses electrons.

Oxidizing agent gets reduced in the process while reducing agent gets oxidized.

what are the uses of the periodic table​

Answers

Answer:

In today's world, the periodic table is very valuable for both students and scientists since it allows them to forecast the sorts of chemical reactions in which a specific element is likely to engage. Rather than memorizing facts and figures for each element, students and scientists can learn a great deal by simply looking at the table. They can learn about an element's reactivity, whether it is likely to conduct electricity, whether it is hard or soft, and many other characteristics by simply looking at the table.

Groups are made up of elements that are in the same column as one another and have attributes that are comparable to one another. If we look at the first column (the alkali metals), for example, we see that they are all metals that have a 1+ charge in reactions, react quickly with water and combine easily with nonmetals.

Periods are made up of elements that are arranged in a row next to one another and have the same maximum unexcited electron energy level as one another.

The periodic table also has the advantage of providing all the information you need to balance chemical processes at a glance, which is a very valuable feature. The atomic number and, in most cases, the atomic weight of each element are included in the table. The group of an element indicates the characteristic charge of that element.

12.04428152 x [tex]10^{23}[/tex] cobalt atoms are in 2 moles of cobalt.

What are moles?

A mole is defined as 6.02214076 ×[tex]10^{23}[/tex]

of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

One mole of cobalt is equal to 6.02214076 ×[tex]10^{23}[/tex] atoms.

2 moles of cobalt is equal to 6.02214076 × [tex]10^{23}[/tex]atoms x 2

12.04428152 x [tex]10^{23}[/tex]

You also have a coefficient of 2 in front of (NH4)3, so that means you would multiply 12 H atoms by 2 and 3 N by 2, giving you 24 hydrogen atoms and 6 nitrogen atoms.
You also have 1 Phosphorus atom, and 4 oxygen atoms, so now add all your individual atoms up:

What will the final temperature of the a block of brass with a mass of 30.6 g is at 87.4°C
after it's added to 62.3 g of water at 28.3°C. The specific heat of aluminum is 0.380
J/gºC.

Answers

The final temperature of the block of brass with a mass of 30.6 g at 87.4°C is 30.82°C.

SPECIFIC HEAT CAPACITY:

The amount of heat absorbed or released by a substance can be calculated using the following formula:

Q = m × c × ∆T

Q(water) = - Q(metal)

(m × c × ∆T) water = - (m × c × ∆T) metal

According to this question;

METAL:

m = 30.6gc = 0.380 J/g°C∆T = T - 87.4°C

WATER:

m = 62.3gc = 4.184J/g°C∆T = T - 28.3°C

62.3 × 4.184 × (T - 28.3) = - {30.6 × 0.380 × (T - 87.4)}

260.7T - 7376.8 = - {11.63T - 1016.3}

260.7T - 7376.8 = -11.63T + 1016.3

260.7T + 11.63T = 1016.3 + 7376.8

272.33T = 8393.1

T = 8393.1 ÷ 272.33

T = 30.82°C

Therefore, the final temperature of the block of brass with a mass of 30.6 g at 87.4°C is 30.82°C.

Calculate the solubility of copper (II) iodate in 0.16 M copper (II) nitrate. Ksp* is 7.4x10-8 M3. *You should know that the Ksp must refer to the copper iodate because all nitrate compounds are soluble and strong electrolytes!

Answers

Answer:

solubility in presence of 0.16M Cu(IO₃⁻)₂ = 3.4 x 10⁻⁴M*

Explanation:

        Cu(IO₃⁻)₂ ⇄           Cu⁺²          +   2(IO₃⁻)        

C(i)    ----------                0.16M                 0M

ΔC    ----------                   +x                   +2x

C(f)    ----------      0.16 + x ≅ 0.16M*        2x

Ksp = [Cu⁺²][IO₃⁻]²

7.4 x 10⁻⁸M³ = 0.16M(2x)² = 0.64x²

x = solubility in presence of 0.16M Cu(IO₃⁻)₂ = SqrRt(7.4x10⁻⁸M³/0.64M²)

= 3.4 x 10⁻⁴M*

*Note: This is consistent with the common ion effect in that a reduction in solubility is expected. The normal solubility of Cu(IO₃⁻)₂ in pure water at 25°C is ~2.7 x 10⁻³M.
