Answer:

Fe₂O₃ and C are reactants

Fe and CO₂ are products

Explanation:

Reactants:

Chemical species that are present on left side of chemical reaction equation are called reactants.

Product:

Chemical species that are present on right side of chemical reaction equation are called product.

Chemical equation:

2Fe₂O₃ + 3C  →  4Fe + 3CO₂

In this reaction 2 mole of iron oxide is react with three moles of carbon and produced four moles of iron and three moles of carbon dioxide. There are equal numbers of atoms of all elements present on both side of chemical reaction so this reaction follow the law of conservation of mass.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Explanation:

This law was given by french chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

The principal quantum number (n): specifies the maximum number of electrons. specifies the 3-D shape of the orbital. none of the
kodGreya [7K]

The principal quantum number (n): specifies the principal shell of the orbital.

The answer is option D.

The important quantum number (n) describes the dimensions of the orbital. Orbitals for which n = 2 are larger than those for which n = 1, as an example. Because they have got opposite electric costs, electrons are interested in the nucleus of the atom.

The numerals, called essential quantum numbers, imply strength degrees as well as the relative distance from the nucleus. A 1s electron occupies the energy stage nearest the nucleus.

A 2s electron, less strongly certain, spends most of its time farther far from the nucleus.

A superconductor performs best at??
Charra [1.4K]

very cold temperatures

Explanation:

A superconductor performs best at very cold temperatures.

A superconductor is a perfect conductor that is able to allow the passage of electricity and heat without resistance.

  • In superconductors, under certain conditions, resistance ceases to exist.
  • Examples are aluminium, niobium e.t.c
  • A conductor allows heat and current to pass through but with little resistance.

The empirical formula of a compound is ch. it's molar mass is 52.07 g/mole. What is its molecular formula
Rina8888 [55]
For this item, we find first the mass of the compound with the empirical formula. That is,
                             molar mass = 12 (for C) + 1 (for H)
                                                   = 13 g/mole
Then, we divide the given mass of the molecular formula by the mass of the empirical formula. 
                                    n = 52.07 / 13 = 4
Therefore, the molecular formula is C₄H₄.
