Identify the geometry of the complex ion if the hybridization is d2sp3. linear square planar octahedral trigonal planar tetrahedral

Answers

Answer 1
Answer: Octahedral   is  the  geometry  of the   complex   ion   which   has  d2sp3   hybridization.

 The  octahedral   has  eight   faces   hence  the  prefix  octa.    Octahedral  molecular   geometry   describe  the  shape  of  compound  with  six  atom   or  groups  of atoms  or  ligands  symmetrically  arranged  around  a  central  atom.The  octahedron   is one   of the  platonic  solids.

The amount of sulfuric acid produced can be determined by titration with sodium hydroxide of known concentration. A 631.0 g sample of air that is known to contain sulfur dioxide was reacted with excess hydrogen peroxide. Given that 18.50 mL of 0.00250 M NaOH ( aq ) was required to neutralize the H 2 SO 4 ( aq ) produced, calculate the mass percentage of SO 2 ( g ) in the air sample.

Answers

Answer:

0.000234 %

Explanation:

Equation of reaction of SO₂ and H₂O₂

SO₂ + H₂O₂  → H₂SO₄

Equation of neutralization of NaOH and H₂SO₄

H₂SO₄ + 2 NaOH → Na₂SO₄ + 2 H₂O

Molar mass of NaOH = 29.997 g/mol

molar mass of H₂SO₄  = 98.079 g/mol

molar mass of SO₂ =64.066 g/mol

number of moles of NaOH = molarity × volume in L = 0.00250 M × (18.50 / 1000) = 0.00004625 mol

comparing the equation

2 moles of NaOH requires 1 mole of H₂SO₄  

0.00004625 mol will require 0.000023125 mole of H₂SO₄  

1 mole of SO₂  produced 1 mole of H₂SO₄  

0.000023125 mole of SO₂ will produce 0.000023125 mole of H₂SO₄  

Mass of SO₂ = 0.000023125 mole × 64.066 g/mol ( mole x molar mass) = 0.00148 g

mass percentage of SO₂ = 0.00148 g  / 631 g × 100 = 0.000234 %

Sharon earns $25 per item she sells plus a base salary of $100 per week. write and solve an inequality to find how many items she must sell to earn at least $700 per week . provide your conclusion as a complete sentence.

Answers

Sharon earns $25 per item. This means that this number is increasing with each item sold, then you will have a variable with this number, such as 'x'.

Plus a base salary of $100 per week. This means that this number is always true for each week and will not change when looking at a weekly perspective.

How many items must she sell to earn at least $700 per week. This is the end goal or even slightly over $700.

To set it up:

25x + 100 ≥ 700

To solve:

25 x + 100 ≥ 700
         - 100   -100
______________
25x            ≥  600
___                ___
25                    25
_______________
     x           ≥     24

In pole beans, green pods (G) are a dominate trait, while yellow pods(g) are a recessive trait. A bean plant with a GG genotype is crossed with a second plant that has a gg genotype. If the cross produces 500 spring, approximately how many of the offspring will have green pods?

Answers

All 500 of the offspring should have green pods. G is dominant trait.
g g
-------------
G Gg | Gg
--------------
G Gg | Gg
----------------

The punnet square shows that all of the offspring are hererozygus. The dominant trait which is green will be shown over the recessive trait which is yellow.

100% of the offspring should have green pods.

Genotype
100% heterozygus (different) Gg

Phenotype
100% green

Answer:

d

Explanation:

Because all 500 of the offspring will have the dominant (G) allele, so all 500 will be green.

The empirical formula of a gaseous fluorocarbon is CF2. At a certain temperature and pressure, a 1-L volume holds 8.93 g of this fluorocarbon, whereas under the same conditions, the 1-L volume holds only 1.70 g gaseous fluorine (F2). Determine the molecular formula of this compound.

Answers

Answer:

C₄F₈

Explanation:

Using their mole ratio to compute their mass

molar mass of carbon = 12.0107 g/mol

molar mass of fluorine gas = 37.99681

let x = mass of carbon

given mass of fluorine = 1.70 g

x / 12.01067 = 1.70 / 37.99687

cross multiply

x = ( 1.70 × 12) / 37.99687 = 20.4 / 37.99687 = 0.53688 g

mass of one mole of CF₂ = 0.53688 + 1.70 = 2.23688 g

number of mole of CF₂ = 8.93 g / 2.23688 = 3.992 approx 4

molecular formula of CF₂ = 4 (CF₂) = C₄F₈

A fuel cell designed to react grain alcohol with oxygen has the following net reaction: CH3OH(l) + 3 O2(g) --> 2CO2(g) + 3H2O(l)

The maximum work one mole of alcohol can yield by this process is 1320 kJ. What is the theoretical maximum voltage this cell can achieve?

a) 0.760V b) 2.28V c) 1.14V d) 2.01V

Answers

Answer:

b. E = 2,28V

Explanation:

The maximum work is the same than ΔG. As ΔG could be written as:

ΔG = nFE (1)

Where n is moles of electrons transferred, F is faraday constant (96485 J/Vmol) and E is the voltage of the cell.

For the reaction:

CH₃OH(l) + ³/₂O₂(g) → CO₂(g) + 2H₂O(l)

The oxidation state of C in CH₃OH is -2 but in CO₂ is +4, that means transferred electrons are +4 - -2 = 6e⁻

Replacing in (1):

1320x10³ J = 6mol e⁻×96485J/Vmol×E

E = 2,28V

I hope it helps!
