<u>Answer:</u> The unbalanced chemical equations are written below.
<u>Explanation:</u>
An unbalanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is not equal to the total number of individual atoms on the product side. These equations does not follow law of conservation of mass.
The chemical equation for the reaction of nitrogen gas and oxygen gas follows:
The product formed is nitrogen dioxide.
The chemical equation for the decomposition of dinitrogen pentaoxide follows:
The product formed is dinitrogen tetroxide and oxygen gas.
The chemical equation for the reaction of ozone to oxygen gas follows:
The product formed is oxygen gas.
The chemical equation for the reaction of chlorine and sodium iodide follows:
The product formed is sodium chloride and iodine gas
The chemical equation for the reaction of magnesium and oxygen gas follows:
The product formed is magnesium oxide
Answer:
Explanation:
The glass (which does not crystallize even though it is accepted) of a window is NOT a mineral, since it is neither a substance of natural origin (although it is manufactured from natural components) nor does it have a defined crystalline structure, that is, the atoms they are not arranged in an orderly and regular way along axes and planes forming flat faces that keep a symmetry.
Remember that a mineral is defined as a solid, inorganic, homogeneous substance, of natural origin, with a crystalline structure and a determined and well-defined chemical composition within narrow margins and that has regular and characteristic physical properties.
presence of heat can change solid tu liquid
and liquid to gas
PbH4 will be formed as a result of a polar covalent bond between the H and the Pb.
Since H is more electronegative than the Pb, it is, thus, expected that the H would be able to pull the electron charge towards itself. This will result in the H being negative.
Based on this:
PbH4 would be expected to <span>have polar covalent bonds with a partial negative charges on the H atoms. </span>
