Answer:

Answer below

Explanation:

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.

Explain how the isotopes of an element differ
patriot [66]

Isotopes of an element will contain the same number of protons and electrons but will differ in the number of neutrons they contain. In other words, isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.

A car tire has a pressure of 2.38 atm at 15.2 c. If the pressure inside reached 4.08 atm, the tire will explode. How hot would t
stich3 [128]

The correct answer is 221.06 °C hot.  

If P₁ is the pressure at T₁ and P₂ is the pressure at T₂ then,  

P₁/T₁ = P₂/T₂

It is given that P₁ = 2.38 atm

T₁ = 15.2 degree C = 273 + 15.2 = 288.2 K

P₂ = 4.08 atm

T₂ = x

Thus, 2.38 / 288.2 = 4.08 / x  

x = (4.08 × 288.2) / 2.38  

x = 494.06 K

x = 494.06 - 273 °C = 221.06 °C

Therefore, the tire would get 221.06 °C hot.

The teacher prepares 2.50 liters (l) of a salt solution for a class experiment. how many quarts (qt) are in 2.50 l? (1 l =1.06 q
trasher [3.6K]

The teacher prepares 2.50 liters (l) of a salt solution for a class experiment, in this quantity 2.65 quartz are present.

<h3>What is conversion factor?</h3>

Conversion factor is a quantity which will be multiplied or divide with any other measurement for the conversion of that measurement.

Given that quantity of salt solution = 2.50 L

We know that, 1 L = 1.06 qt

Here conversion factor is 1.06 qt/L as it will be multiplied on given measurement to convert into quartz as:

2.50L = 2.50L × 1.06qt/L = 2.65qt

Hence required value is 2.65qt.
