Select the correct answer. What inference can be drawn from the graph? a graph of reactant and product concentration vs. time; a red curve shows the reactant decreasing and a blue curve shows the product concentration increasing over time; the two curves do not intersect; the chemical equation shows A + B reacting to produce C + D A. The reaction between A and B is reactant favored. B. The amount of product is greater than the amount of reactant. C. The reaction uses all its reactants to form products. D. The reaction reaches equilibrium at 1.5 seconds. E. The amount of reactants is highest at equilibrium.
Answers
Answer:
The answer to the graph below is B
Explanation:
The graph has been depicting that there has been higher concentration of the product as compared to the reactant in the reaction mixture. Thus, option B is correct.
The graph drawn has been the concentration of the reactant and product with respect to the time. The line red has been the reactant concentration, while blue line has been the product concentration.
With the chemical reaction, there has been the decrease in the reactant concentration with the increase in the product concentration.
The graph has been depicting that there has been higher concentration of the product as compared to the reactant in the reaction mixture. Thus, option B is correct.

An aqueous solution of Iron(III) sulfate, Fe2(SO4)3, is mixed with an aqueous solution of Sodium hydroxide, NaOH. Write:_______. a. balanced molecular equation b. the total ionic equation c. the net ionic equation showing all phases.
Answers
Answer:
a.
[tex]Fe_2(SO_4)_3(aq)+6NaOH(aq)\rightarrow 2Fe(OH)_3(s)+3Na_2SO_4(aq)[/tex]
b.
[tex]2Fe^{2+}(aq)+3(SO_4)^{2-}(aq)+6Na^+(aq)+6OH^-(aq)\rightarrow 2Fe(OH)_3(s)+6Na^+(aq)+3(SO_4)^{2-}(aq)[/tex]
c.
[tex]Fe^{2+}(aq)+3OH^-(aq)\rightarrow Fe(OH)_3(s)[/tex]
Explanation:
Hello!
In this case, since the reaction between sodium hydroxide and iron (III) sulfate yields iron (III) hydroxide, an insoluble base, and sodium sulfate, a soluble salt, we can write the molecular equation as shown below:
a.
[tex]Fe_2(SO_4)_3(aq)+6NaOH(aq)\rightarrow 2Fe(OH)_3(s)+3Na_2SO_4(aq)[/tex]
Now, for the total ionic equation, we make sure we separate the aqueous species in ions (dissociation) in order to write:
b.
[tex]2Fe^{2+}(aq)+3(SO_4)^{2-}(aq)+6Na^+(aq)+6OH^-(aq)\rightarrow 2Fe(OH)_3(s)+6Na^+(aq)+3(SO_4)^{2-}(aq)[/tex]
Finally, the net ionic equation comes up by cancelling out the spectator ions, those at both reactants and products sides:
[tex]2Fe^{2+}(aq)+6OH^-(aq)\rightarrow 2Fe(OH)_3(s)[/tex]
Or just:
c.
[tex]Fe^{2+}(aq)+3OH^-(aq)\rightarrow Fe(OH)_3(s)[/tex]

Answers
Answer:
Mass is the amount of matter in an object. The distance is how far apart two places are from each other. They are related because the more mass the more gravitational force as then there is more pressure and then the gravitational force attracts the two objects closer. The more distance, the less the gravitational force as then the gravitational force will have more trouble attracting the two objects toward each other.
determine how many millilitres of a 4.25 M HCl solution are needed to react completely with 8.75 g CaCO3?
2HCl + CaCO3 --> CaCl2 + CO2 + H2O
Answers
Answer:
41 mL
Explanation:
Given data:
Milliliter of HCl required = ?
Molarity of HCl solution = 4.25 M
Mass of CaCO₃ = 8.75 g
Solution:
Chemical equation:
2HCl + CaCO₃ → CaCl₂ + CO₂ + H₂O
Number of moles of CaCO₃:
Number of moles = mass/molar mass
Number of moles = 8.75 g / 100.1 g/mol
Number of moles = 0.087 g /mol
Now we will compare the moles of CaCO₃ with HCl.
CaCO₃ : HCl
1 : 2
0.087 : 2/1×0.087 = 0.174 mol
Volume of HCl:
Molarity = number of moles / volume in L
4.25 M = 0.174 mol / volume in L
Volume in L = 0.174 mol /4.25 M
Volume in L = 0.041 L
Volume in mL:
0.041 L×1000 mL/ 1L
41 mL

What is the molarity of an aqueous solution that contains 0.072 g C2H6O2 per gram of solution? The density of the solution is 1.40 g/mL.
Answers
Answer:
1.626 M
Explanation:
Let's start by calculating how many grams of C₂H₆O₂ are there per mL of solution:
1 mL of solution weighs 1.40 g.1.40 g of solution * [tex]\frac{0.072gC_2H_6O_2}{1gsolution}[/tex] =0.1008 g C₂H₆O₂So the C₂H₆O₂ concentration can be expressed as 0.1008 g/mL.
Now we convert g/mL to molarity, using the molar mass of C₂H₆O₂:
0.1008 g C₂H₆O₂ ÷ 62 g/mol = 1.626x10⁻³ mol C₂H₆O₂(1 mL = 0.001 L)
1.626x10⁻³ mol C₂H₆O₂ / 0.001 L = 1.626 MThe molarity of the solution is given as 1.626M
We can calculate the mass of C₂H₆O₂ in mL of solution:
1 mL of solution weighs 1.40 g.
1.40 g of solution × 0.072/1
=0.1008 g C₂H₆O₂
C₂H₆O₂ concentration = 0.1008 g/mL.
Conversion of g/mL to molarity
0.1008 g C₂H₆O₂ ÷ 62 g/mol = 1.626x10⁻³ mol C₂H₆O₂
(1 mL = 0.001 L)
1.626x10⁻³ mol C₂H₆O₂ / 0.001 L = 1.626 M

You wish to make a 0.405 M hydrochloric acid solution from a stock solution of 3.00 M hydrochloric acid. How much concentrated acid must you add to obtain a total volume of 100 mL of the dilute solution?
Answers
Answer:
Explanation:
We have to make 100 mL 0f .405M HCl from 3 M solution of HCl .
volume of 3M to be taken required . Let this volume be V litre .
V litre of 3M will contain 3 V moles of HCl .
moles contained by 100 mL of ,405 HCl = .405 x .1 = .0405 moles .
So 3V = .0405
V = .0405 / 3 litre
= .0405 x 1000 / 4 mL
= 10.125 mL
So we have to take 10.125 mL of 3M HCl and add water to them to make its volume 100 mL .
The rate constant for the reaction 3A equals 4b is 6.00×10 how long will it take the concentration of a to drop from 0.75 to 0.25M from the unit of the rate constant we know it is a second reaction order?a) 2.2×10^−3 min

c) 180 min
d) 440 min
e) 5.0×10^2 min
Answers
This question is incomplete, the complete question is;
The rate constant for the reaction 3A equals 4B is 6.00 × 10⁻³ L.mol⁻¹min⁻¹.
how long will it take the concentration of A to drop from 0.75 to 0.25M ?
from the unit of the rate constant we know it is a second reaction order
OPTIONS
a) 2.2×10^−3 min
b) 5.5×10^−3 min
c) 180 min
d) 440 min
e) 5.0×10^2 min
Answer:
it will take 440 min for the concentration of A to drop from 0.75 to 0.25M
Option d) 440 min is the correct answer
Explanation:
Given that;
Rate constant K = 6.00 × 10⁻³ L.mol⁻¹min⁻¹
3A → 4B
given that it is a second reaction order;
k = 1/t [ 1/A - 1/A₀]
kt = [ 1/A - 1/A₀]
t = [ 1/A - 1/A₀] / k
K is the rate constant(6.00 × 10⁻³)
A₀ is initial concentration( 0.75 )
A is final concentration(0.25)
t is time required = ?
so we substitute our values into the equation
t = [ (1/0.25) - (1/0.75)] / (6.00 × 10⁻³)
t = 2.6666 / (6.00 × 10⁻³)
t = 444.34 ≈ 440 min {significant figures}
Therefore it will take 440 min for the concentration of A to drop from 0.75 to 0.25M
Option d) 440 min is the correct answer

Calculate the nuclear binding energy in mega-electronvolts (MeV) per nucleon for Th232. Th232 has a nuclear mass of 232.038 amu.
Answers
Answer:
1720 MeV
Explanation:
Thorium has 90 protons and 142 neutrons
The mass of each proton is 1.007277 amu
The mass of each neutron is 1.008665 amu
The mass of 90 protons is 90 * 1.007277 amu = 90.65493 amu
The mass of 142 neutrons is 142 * 1.008665 amu = 143.23043 amu
Total calculated mass of nucleons = 90.65493 amu + 143.23043 amu = 233.88536
Mass defect = 233.88536 amu - 232.038 amu = 1.84736 amu
We convert from amu to MeV using the conversion factor of 931
Binding energy = 1.84736 amu * 931 = 1720 MeV

Grignard reagent reacts with aldehydes and ketones to form alcohol. However the classification (that is; Primary, secondary and tertiary) varies depending on which it reacts with.
2-butanone is a ketone.
Ketones reacts with Grignard reagent to form tertiary alcohol
Butanal is an aldehyde.

It takes 30 minutes to feel the effects of alcohol.
Explanation:
It may take an hour to metabolize a drink, but it takes approximately thirty minutes before you feel alcohol's effects. This is a good gauge for pacing yourself. Drinking more than one drink every 30 minutes means you are probably drinking too much, too fast.
