Mr. Smith creates a new sauce because he wants to increase his restaurant’s sales by creating a burger that reduces gas production. He recruits 100 customers with a history of gas problems. He has 50 of them eat burgers with the new sauce. The other 50 eat burgers with sauce that looks just like the new sauce, but it is really just a mixture of mayonnaise and food coloring. Both groups were told that they were getting the new sauce. Mr. Smith has all of the participants track their production of gas for 24 hours. Mr. Smith finds that customers who ate the new sauce had less gas production for 24 hours.

Answer: C6H12O6 is formed by a covalent bond, the rest of the options are formed by ionic bonds.

Answer:

for points

Explanation:

loll

Answer:

True

Explanation:

The arrangement of three groups COOH, CO, OH in the order of reducing boiling point is as follow -

 COOH > OH > CO

COOH gets strongly polarised due to the presence of electron withdrawing carboxy group and hence have strong H+ bonds as compared to that of alcohol.

Hence the given statement is true.

Given

230 g SO2

30.5 moles LiNO3

Required

moles and molecules

Solution

mol = mass : molar mass

1 mol = 6.02 x 10²³ particles(molecules, atoms, ions)

1. 230 g x 1 mol/64,066 g  =3.59 mol

2. 30.5 moles x 6.02 x 10 ²³ molecules / 1 mol = 1.836 x 10 ²⁵ molecules

Answer:

The element is a nonmetal

Explanation:

Elements are broadly classified into metals and non metals. Metals conduct electricity while non metals do not conduct electricity.

If we look at this scenario described in the question, we can easily decipher that the element is a nonmetal because the LED stays dark. The LED should have been lit if electricity was passed through the element in question.

Hence, the element is a non metal.

Answer:

[tex][PCl_3]=[Cl_2]=0.068M[/tex]

[tex][PCl_5]=0.385M[/tex]

Explanation:

Hello!

In this case, since the equilibrium expression for the considered equation is:

[tex]Kc=\frac{[PCl_5]}{[Cl_2][PCl_3]}[/tex]

Which can be written in terms of the reaction extent and the ICE chart and the initial concentrations of 0.453 M as shown below:

[tex]83.3=\frac{x}{(0.453M-x)(0.453M-x)}[/tex]

We can solve for x as follows:

[tex]x=0.385M[/tex]

In such a way, we obtain the following concentrations at equilibrium:

[tex][PCl_3]=[Cl_2]=0.453M-0.385M=0.068M[/tex]

[tex][PCl_5]=0.385M[/tex]

The potential energy : PE = 5.88 x 10⁻³ J

Given

height = h = 20 cm = 0.2 m

mass = 3 grams = 3 x 10⁻³ kg

Required

The potential energy

Solution

The energy produced from its position is called potential energy (PE)  

which can be formulated as:  

PE = m. g. h

Input the value :

PE = 3 x 10⁻³ x 9.8 x 0.2

PE = 5.88 x 10⁻³ J

Answer:

[tex]C_4H_8O_2[/tex]

Explanation:

Hello!

In this case, since the combustion of this compound has only one source of carbon, the carbon dioxide, we can compute both mass and moles of carbon in 4.401 grams of CO2:

[tex]n_C = 4.401gCO_2*\frac{1molCO_2}{44.01gCO_2}* \frac{1molC}{1molCO_2} =0.1molC\\\\m_C = 0.1molC*\frac{12.01gC}{1molC} = 1.201gC[/tex]

Next, we do the same for hydrogen in water, as the only source of this atom in the products:

[tex]n_H = 1.802gH_2O*\frac{1molH_2O}{18.02gH_2O}* \frac{2molH}{1molH_2O} =0.2molH\\\\m_H = 0.2molC*\frac{1.01gH}{1molH} = 0.202gH[/tex]

Thus, we compute the mass and then the moles of oxygen considering the 2.203-g sample of dioxane:

[tex]m_O = 2.203g-m_C-m_H=2.203g-1.202g-0.202g = 0.799gO\\\\n_O =0.799gO*\frac{1molO}{16.0gO} =0.05molO[/tex]

Next, we divide the moles of C, H and O by the moles of O as the fewest in the molecule to find their subscripts in the empirical formula:

[tex]C:\frac{0.1mol}{0.050mol}=2 \\\\H:\frac{0.202mol}{0.050mol} =4\\\\O:\frac{0.050}{0.050}=1 \\\\[/tex]

[tex]C_2H_4O[/tex]

Whose molar mass is 44.1 g/mol. Thus, since the molar mass of the compound is 88.1 g/mol, we see a factor of 2 by which the empirical formula should be multiplied to get the molecular one, therefore, we obtain:

[tex]C_4H_8O_2[/tex]

Best regards!

Explanation:

I took the test

Sulfur act as a reducing agent and chlorine acts as an oxidizing agent.

The charge is based on the number of electrons assigned to an atom as compared to the neutral atom

Given reaction:-

[tex]S+Cl_2 \rightarrow SCl_2[/tex]

The oxidation state of sulfur in the left side is 0, but in right side is +2. So, sulfur is oxidized. The oxidation number of Cl in the reactant side is 0 and n the product side is -1. So, Cl acts as oxidizing agent.

100g/220g*100 is the correct answer- I took the test

Answer:

answer:

given;

total gram=70+50+100=220g

total gram of chocolate=100g

percentage composition of chocolate=total gram of chocolate/total gram ×100%

=100g/220g ×100 is your answer

Answer:

5

Explanation:

Given that the formula is;

1/λ= R(1/nf^2 - 1/ni^2)

λ = 93.7 nm or 93.7 * 10^-9 m

R= 1.097 * 10^7 m-1

nf = ?

ni = 1

From;

ΔE = hc/λ

ΔE = 6.63 * 10^-34 * 3* 10^8/93.7 * 10^-9

ΔE = 21 * 10^-19 J

ΔE = -2.18 * 10^-18 J (1/nf^2 - 1/ni^2)

21 * 10^-19 J = -2.18 * 10^-18 J (1/nf^2 - 1/ni^2)

21 * 10^-19/-2.18 * 10^-18 = (1/nf^2 - 1/1^2)

-0.963 = (1/nf^2 - 1)

-0.963 + 1 = 1/nf^2

0.037 = 1/nf^2

nf^2 = (0.037)^-1

nf^2 = 27

nf = 5

Answer:

110g/mol is the molar mass of compound A

Explanation:

The osmotic pressure of a solution could be obtained using the equation:

π = i*M*R*T -Solving molarity we can find the molar mass of the solute A-

Where π is osmotic pressure (7.38atm)

i is Van't Hoff's factor (1 for nonelectrolytes)

M is molarity (Our incognite)

R is gas constant (0.082atmL/molK)

T is absolute temperature (25°C + 273.15 = 298.15K)

Computing the values:

7.378atm = 1*M*0.082atmL/molK*298.15K

0.3018 mol/L is the concentration of the solution.

The volume of the solution is 15mL = 0.015L. Moles of the solute are:

0.3018 mol/L * 0.015L = 4.527x10⁻³ moles

Molar mass is the ratio between mass of the compound (0.50g) and the moles (4.527x10⁻³ moles). That is:

0.50g / 4.527x10⁻³ moles =

Answer:

Below 7

Explanation:

The equivalence point, or stoichiometric point, of a chemical reaction is the point at which chemically equivalent quantities of reactants have been mixed(Wikipedia).

For a strong acid-weak base titration, the pH at the equivalence point is usually below 7. This owes to the fact that a conjugate acid  is produced in the course of the reaction which interacts with water to produce hydronium (H3O+) ions.

Explanation:

The bond angle for methane is the angle determined by two consecutive hydrogen atoms and the central carbon atom.

Methane, a tetrahedron has the structural formula:

                             H

                              |

                    H  -   C   -  H

                              |

                             H            Methane, CH4

The bond angle is the angle between the H-C-H atoms and is 109.5degrees.

Decomposition: A substance breaks down to smaller species.

molarity = moles of solute/liters of solution

We know the moles of solute: 0.875 moles of glucose. We can easily determine the liters of solution by using the mass of water given (1.5 kg) and the density of water (approximately 1 kg/L): they're, for all intents and purposes, equal (the approximation isn't large enough to be appreciable here, nor would the volume of the solution appreciably change since the solute is a solid that will dissolve into the solvent). So, we have 1.5 L of solution.

Now, we plug in what we have:

molarity = 0.875 moles of glucose/1.5 L of solution = 0.58 M glucose

The answer is provided to two significant figures since we're given the mass of water to two significant figures.
