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’.

What is the mass of water necessary to generate 11.2 L of hydrogen gas if calcium metal reacts with water at standard temperatur
12345 [234]

Answer:

The mass of water is 18 g

Explanation:

The reaction of calcium with water can be represented in the equation below:

Ca + 2H₂O --------->Ca(OH)₂ +H₂

1 Mole of gas at STP = 22.4L

From the displacement reaction above, calculate the mass of water that will produce 22.4L of hydrogen gas at STP.

Mass of 2H₂O = 2(2x1 + 16) = 2X18 = 36 g/mol

Using proportional analysis;

36 g of 2H₂O produced 22.4 L of H₂, then

what mass of 2H₂O will produce 11.2L of  H₂ ?

Mathematically,

22.4 L ----------------------------------> 36g

11.2 L -----------------------------------> ?

Cross and multiply, to obtain the expression below

= (11.2 X 36)/22.4

= 18 g

Therefore, the mass of water is 18 g

In this reaction, the covalent bonds in the molecules of hydrogen and oxygen are broken.
Westkost [7]

Answer: Endothermic

Explanation:

Bond-breaking is an endothermic process. Energy is released when new bonds form. Bond-making is an exothermic process. Whether a reaction is endothermic or exothermic depends on the difference between the energy needed to break bonds and the energy released when new bonds form.
