Answer:

Pure substances are made up of a bulk quantity of individual atoms or molecules.

Each pure substance is made up of one of Individual atoms of the same type that are connected to form extended structures.

A chemical reaction happens when substances break apart or combine to form one or more new substances.

  • New substances form when bonds break and new bonds form.

Based on the balanced chemical equation for the preparation of malachite, what is the composition of the bubbles formed when sod
spin [16.1K]

Answer:

Carbon Dioxide = CO2

Explanation:

The synthesis of Malachite is seen in the chemical formula:

CuSO 4 . 5H2O(aq) + 2NaCO3(aq) --> CuCO 3 Cu(OH) 2 (s) + 2Na 2 SO 4 (aq) + CO 2 (g) + 9H 2 O(l)

The bubbles mentioned in the question hints that our interest is the compounds in their gseous phase  (g).

Upon examining the chemical equation, only CO2 is in the gaseous state and hence the only one that can be formed as bubbles,

Copper atoms are used to produce pennies. The copper atoms in pennies share many electrons. Pennies contain
kaheart [24]

Answer:

Metallic bonds

Explanation:

Metallic bonds joins atoms of metals and atoms of alloys together. The copper used in making pennies is a metallic substance so it contains metallic bonds.

  • The formation of this bond type is predicated on the large atomic radius, low ionization energy and large number of electrons in the valence shell.
  • The bond is an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud.
  • The electron cloud is jointly formed by all the atoms by losing their outermost shell electrons.

This way the bond in pennies are metallic in nature.

Gasoline contains only hydrogen and carbon atoms, yet nitrogen oxide and nitrogen dioxide are produced when gasoline burns. What
White raven [17]

Answer:

The answer to the question is

The source of the nitro- gen and oxygen atoms is from the atmosphere

Explanation:

When gasoline burns oxygen from the atmosphere supports the combustion reaction.

For example the internal combustion engine of a motor vehicle pulls in air from the surrounding atmosphere to make use of the oxygen in aiding the combustion of the gasoline to drive the pistons that ultimately moves the vehicle. The air from which the oxygen is absorbed also contains more amount of Nitrogen by percentage than oxygen. The nitrogen therefore enters into the combustion reaction that eventually produces nitrogen oxide and nitrogen dioxide
