Physical changes dont change the chemical makeup of an object. An example would be to tear a piece of paper. Tearing the paper doesnt change how the paper was made chemically

Chemical changes on the other hand do change the chemical makeup of an object. An example of a chemical change would be to bake a cake. The reason being that the chemical makeup of the cake batter is changed so that the actual cake is formed.

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.

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.

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.

At constant temperature, if the volume of the gas is doubled, the pressure also doubles. The new pressure of the gas is 50°C.

Charles's law states that "the volume occupied by a definite quantity of gas is directly proportional to its absolute temperature.

It is expressed as;

V₁/T₁ = V₂/T₂

Given that;

If final volume is double of initial volume.

V₁/T₁ = V₂/T₂

V₁T₂ = V₂T₁

T₂ = V₂T₁ / V₁

T₂ = ( 1000cm³ × 25°C ) / 500cm³

T₂ = 25000m³°C / 500cm³

T₂ = 50°C

At constant temperature, if the volume of the gas is doubled, the pressure also doubles. The new pressure of the gas is 50°C.

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 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
