<u>answer</u> 1<u> </u><u>:</u>

Law of conservation of momentum states that

For two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied. Therefore, momentum can neither be created nor destroyed.

<u>answer</u><u> </u><u>2</u><u>:</u><u> </u>

When a substance is provided energy<u> </u>in the form of heat, it's temperature increases. The extent of temperature increase is determined by the heat capacity of the substance. The larger the heat capacity of a substance, the more energy is required to raise its temperature.

When a substance undergoes a FIRST ORDER phase change, its temperature remains constant as long as the phase change remains incomplete. When ice at -10 degrees C is heated, its temperature rises until it reaches 0 degrees C. At that temperature, it starts melting and solid water is converted to liquid water. During this time, all the heat energy provided to the system is USED UP in the process of converting solid to the liquid. Only when all the solid is converted, is the heat used to raise the temperature of the liquid.

This is what results in the flat part of the freezing/melting of condensation/boiling curve. In this flat region, the heat capacity of the substance is infinite. This is the famous "divergence" of the heat capacity during a first order phase transition.

There are certain phase transitions where the heat capacity does not become infinitely large, such as the process of a non-magnetic substance becoming a magnetic substance (when cooled below the so-called Curie temperature).

What mass of zinc is needed to react with 23.1g of phosphoric acid according to the following equation?
Hunter-Best [27]

23.01 g of zinc (Zn)

Explanation:

We have the following chemical reaction:

3 Zn + 2 H₃PO₄ = 3 H₂ + Zn₃(PO₄)₂

number of moles = mass / molar weight

number of moles of phosphoric acid = 23.1 / 98 = 0.236 moles

Taking in account the chemical reaction, we devise the following reasoning:

if           2 moles of H₃PO₄ are reacting with 3 moles of Zn

then      0.236 moles of H₃PO₄ are reacting with X moles of Zn

X = (0.236 × 3) / 2 = 0.354 moles of Zn

mass = number of moles × molar weight

mass of Zn = 0.354 × 65 = 23.01 g
