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’.

Cream of tartar creates a white-purple flame when burned. What can you hypothesize is a component of the cream
antiseptic1488 [7]

Potassium can be a component of the cream.

<h3>Why does potassium show white-purple flame when burned?</h3>

An element's presence can be determined using a flame test. The potassium in cream of tartar is what gives it its white-purple color.

Low ionization enthalpy elements allow the flame to display color. Due to low ionization enthalpy, when an element is heated, its valence electrons are quickly excited to higher orbits and emit light as they return to their original orbit. Salts of potassium emit a white-purple color when ignited. The cream of tartar's chemical formula is KC₄H₅O₆.

Which part of the atom is involved in chemical bonding with other atoms?
Leno4ka [110]

Concept:

When an atom has incomplete number of electron in its outermost orbit then it has great tendency to react with another atom which satisfies their octate either by sharing or by transferring their electrons. The involved electrons are called valence electrons.

In case of electrovalent compound, the valance electron complete their octate by transferring their valence electrons while in the covalent compound, they complete their octate by the sharing of their valence electrons.

Hence, the valence electron of the atom is involved in chemical bonding with other atoms.

In a typical mass spectrum, a smaller signal is observed at a mass 1 amu higher than the molecular ion peak. Why
Nina [5.8K]

Answer:

Answer is explained below in the explanation section

Explanation:

Smaller signal is observed at a mass 1 amu because small percentage of the compound will have carbon isotope of 13C instead of 12C.

As we know, mass spectrometry is done as a small compound is first vaporized and then bombarded to ionize it. And then, those ions are accelerated forward and then at some point ions are separated and deflected by the application of magnetic field.

And finally hits the detector to give us a spectrum to read. So, in this whole procedure, there can be a small percentage of carbon isotope of 13C instead of 12C in that compound and showed in the spectrum as a smaller signal at a mass 1 amu.
