Copper and aluminium wire are used to carry electric current. Copper, aluminium and iron are used to make domestic utensils and factory equipment. Thin foils of aluminium are used for wrapping cigarettes, medicines, confectionery, etc. Aluminium is used for making angles, doors, pipes, etc. which are used in the construction of houses. Metals such as sodium, titanium, zirconium, etc. are used in generation of nuclear energy and in space science projects. Mercury is used in thermometers. Magnesium metal is used as a strong reducing agent to prepare other metals. Gold and silver metals are used to make jewellery. Thin foils of silver and gold are used to decorate sweets. Uranium metal is used to generate nuclear energy. Titanium metal is very hard, resistant to corrosion, light, has high melting point and is good conductor of heat and electricity. Because of its unique and useful properties titanium is sometimes called ‘the wonder metal’.

When would formation of a derivative be a necessary step in this experiment?
const2013 [10]
<span>The formation of a derivative being a necessary step in the experiment lies in the importance of the derived structure. Often the derived product confers to reaction pathways which uses less reactive starting materials and more easily proceeds to completion. This also allows us to take a small amount of sample. The derived product at times is a general compound allowing its easy analysis. Often we encounter a product but we find it difficult to analyse it in ways we want. Here lies the essence of forming a derivative which often are simpler compounds allowing easier analysis yet having similar functional groups and structural properties. Also sometimes we encounter problems when our desired product is unstable and forms stable degraded products. But if we somehow manage to synthesize a derivative it may be relatively stable and form no degradation products. It would be stable at least for a significant period of time making it easier to study its properties. The derived product also at times are synthesized using general reaction pathways facilitating a way of easier synthesis and helping it to correlate with other similar reaction pathways and products.So the above paragraph accounts for the need of derivatives. When we encounter problems similar to those mentioned above it becomes necessary for a researcher to form rather synthesize a derivative.</span>

A gas occupies 4.31 liters at a pressure of 0.755 atm. Determine the volume if the pressure is increased to 1.25 atm. (Boyle)
vlabodo [156]

Answer:

<h2>2.60 L</h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{4.31 \times 0.755}{1.25}  =  \frac{3.25405}{1.25}  \\  = 2.60324

We have the final answer as

<h3>2.60 L</h3>

Hope this helps you
