Explanation:

I hope this helps girl

Why is vanilla ice cream white instead of brown?

It is true that Vanilla beans are brown in color and it is interesting that with this brown color ingredient, Vanilla Ice Cream is still white. Well, the vast majority of vanilla flavoring comes in the form of extract. Vanilla beans are very expensive and pure Vanilla has great flavor. When Ice Cream is made, the Vanilla we put in the Ice Cream is very insignificant quantity when compared to the milk powder, sugar, and cream that goes into the Ice Cream. Due to the whipping and procedure of the making, the brown color of Vanilla is lost amongst the huge quantities of other ingredients and we get milky white yummy Vanilla Ice cream

The mass of iron (III) oxide that will be produced would be 22.1 grams

From the equation of the reaction:

[tex]3KOH + Fe(NO_3)_3 --- > 3KNO_3 + Fe(OH)_3[/tex]

The mole ratio of iron (III) nitrate to iron (III) hydroxide is 1:1.

Mole of 50 g iron (III) nitrate = 50/241.86 = 0.207 moles

Equivalent mole of iron (III) hydroxide = 0.207 moles

Mass of 0.207 moles iron (III) hydroxide = 0.207 x 106.87 = 22.1 grams

Hello there! I believe the answer you need is d= M/V. Have a good day,night or miday. Sorry if I'm wrong.

Answer:

P2=672.1 torr

Explanation:

use the formula P1V1=P2V2, plug in the numbers so your equation should look like this (763.9)x(98.8)=P2(112.3) answer should be P2=672.1 torr

The resultant pressure of the sample of gas is 510.9 torr.

Relation between the pressure and volume will be represented by the ideal gas equation PV = nRT, and for the given question required equation is:

P₁V₁ = P₂V₂, where

P₁ & V₁ are the pressure and volume of initial sample.

P₂ & V₂ are the pressure and volume of final sample.

On putting values from the question to the equation, we get

P₂ = (768.6)(93.2) / (140.2) = 510.9 torr

Hence resultant pressure is 510.9 torr.

The specific heat of a substance if a mass of 10.0 kg increases in temperature from 10.0°C to 70.0°C when 2,520 J of heat is applied is 4.2 J/g°C.

The specific heat capacity of a substance can be calculated using the following formula:

Q = m × c × ∆T

Where;

2520 = 10 × c × (70 - 10)

2520 = 600c

c = 4.2 J/g°C

Therefore, the specific heat of a substance if a mass of 10.0 kg increases in temperature from 10.0°C to 70.0°C when 2,520 J of heat is applied is 4.2 J/g°C.

Explanation:

A substance that has a pH value of 14 is a strong base because pH 8 to 14 represents base.

The pH value 1 to 6 indicates acidic, 7 shows neutral whereas pH from 8 to 14 shows basic nature. pH 1 shows strong acid which becomes weak when it goes to 6 while on the other hand, pH 8 is a weak base which increases when it reaches to 14.

So we can conclude that a substance that has a pH value of 14 is a strong base because pH 8 to 14 represents base.

A chemist needs 32.0 g of phenol, for an experiment. The number of moles of phenol is 0.340 mol.

The mole is a SI unit of measurement that is used to calculate the quantity of any substance.

Calculating the moles

[tex]\rm Number\;of \;moles= \dfrac{mass}{molar\;mass}\\\\\rm Number\;of \;moles= \dfrac{32.0}{94.11} = 0.340 moles[/tex]

The molar mass can be calculated by counting the molecules of the elements. Then multiply the molecules of each element with its molar mass and then add the total number, you'll get the molar mass of the compound.

Thus, the number of moles of phenol is 0.340 mol.

When 45.0 mL of a 1.90 M H₂SO₄ solution is added to 95.0 mL of 0.600 M H₂SO₄the molarity of the resulting solution is 0.95 M.

To answer the question, we need to know what molarity is.

Molarity is the number of moles per unit volume with volume in liters.

To find the molarity of the resulting solution, we need to find the number of moles in each solution.

Number of moles, n = MV where

Given that we have 45.0 mL of a 1.90 M H₂SO₄ solution.

M' = 1.90 M and V' = 45.0 mL = 0.045 L

So, n' = M'V'

= 1.90 M × 0.045 L

= 0.0855 mol

Given that we have 95.0 mL of 0.600 M H₂SO₄ solution.

M" = 0.600 M and V" = 95.0 mL = 0.095 L

So, n" = M"V"

= 0.600 M × 0.095 L

= 0.057 mol

The number of moles in the resulting solution is n'" = n' + n"

= 0.0855 mol + 0.057 mol

= 0.1425 mol

The volume of the resulting solution is V"' = V' + V"

= 45.0 mL + 95.0 mL

= 150.0 mL

= 0.15 L

The molarity of the resulting solution is M'" = n"'/V"'

= 0.1425 mol/0.15 L

= 0.95 mol/L

= 0.95 M

So, the molarity of the resulting solution is 0.95 M.

35.5 g of tetrachloroethane is added if 15 grams of chlorine is used with excess [tex]C_2H_2[/tex].

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is  the same for both the reactants and the products.

Balanced chemical equation:

[tex]2Cl_2 (g) + C_2H_2 (g)[/tex] → [tex]C_2H_2Cl_4(l)[/tex]

In your case, 2 moles of chlorine gas are needed to produce 1 mole of tetrachloroethane, which implies that there's a 2:1 mole ratio between the two.

Calculating the mass of tetrachloroethane.

[tex]m[/tex][tex]C_2H_2Cl_4(l)[/tex] = [tex]15 g[/tex] [tex]Cl_2 (g)[/tex] X [tex]\frac{2 mol \;of \;Cl_2}{70 g \;Cl_2}[/tex] X [tex]\frac{1 mol \;of \;C_2H_2Cl_4(l)}{2 mol \;Cl_2}[/tex] X [tex]\frac{167.8 g \;C_2H_2Cl_4(l))}{1 mol \;C_2H_2Cl_4}[/tex]
