The size of the atoms a and the number of holes in the atoms can be used to decode the element.

<h3>What are models?</h3>

A model is a miniature depiction of reality. Molecular models often consists of boxes that contain balls which are used to represent elements. In common parlance, the color is used to show the type of element.

Apart from the color, the size of the atoms a and the number of holes in the atoms can be used to decode the element.

Toluene, C7H8, is used in the manufacture of explosives such as TNT (trinitrotoluene). A 1.500 g sample of liquid toluene was pl
dusya [7]

Answer:

There were 63.67 kJ liberated

If 1 mol of toluene was burned, there would be liberated 3906 kJ / mole

Explanation:

Step 1: Data given

Mass of the toluene sample = 1.500 grams

The temperature of the calorimeter rose from 25.000 °C to 26.413 °C

<em>Write the balanced chemical equation for the reaction in the calorimeter.</em>

C7H8(l)  +  9O2(g) ⇒  7CO2(g) + 4H2O(l)

<u>Step 2:</u> Calculate Q of the calorimeter

Q = C * Δt

Q = 45.06 kJ/ °C * ( 26.413 - 25)

Q =<u> 63.67 kJ </u>

<u>Step 3:</u> Calculate moles of toluene

Moles toluene = mass toluene / molar mass toluene

Moles toluene = 1.500 grams /92.14 g/mol

Moles toluene = 0.0163 moles

<u>Step 4:</u>  Calculate energy per mole

energy per mole = 63.67 kJ / 0.0163 moles = 3906 kJ / mole

Describe the scale used to measure the basicity of a substance. Demonstrate how you could differentiate a weak base from a stron
amm1812

The scale used to measure the basicity of a substance is called the pH Scale. A base which when measured on a pH scale obtains a  value greater than 7 but less than or equal to 10 is weak base and from 10-14 is strong base

<h3>Meaning of Base and basicity</h3>

A base is any substance that has the ability to accept hydrogen ion in water and also netralize an acid when mixed together.

Basicity is an attribute associated with the pH scale measurement of values above 7 to 14.

Basicity increases on the scale from 7 to 14. On the pH scale 7 is neutral. So the higher we go the more basic a solution becomes until it gets to its highest point which is 14.

In conclusion, The scale used to measure the basicity of a substance is called the pH Scale. A base which when measured on a pH scale obtains a  value greater than 7 but less than or equal to 10 is weak base and from 10-14 is strong base
