Answer:
The reaction has a single reactant
Explanation:
Decomposition reaction is a reaction in which an insoluble single compound is heated at a high temperature and decomposes into several products.
Typically, we may see decomposition of calcium carbonate producing calcium oxide and carbon dioxide, this is represented by the following reaction:
Another example would be decomposition of ammonium nitrite. Ammonium nitrite would decompose into nitrogen and water:
Notice that the two examples above share something in common: the two decomposition reactions have a single reactant.
Closely spaced contour lines represent steep slopes, conversely, contour lines that are spaced far apart represent gentle slopes. Contour lines trend up valleys and form a "V" or a "U" where they cross a stream.
<em>The number of protons and electrons in a neutral atom of the element are;</em>
D. 29 protons and 29 electrons
<u>The atomic number of an element is equal to the number of protons in the nucleus of each atom of that element.</u>
<u>Thus copper has an atomic number of 29, all atoms of copper will have 29 protons.</u>
E=hv was the equation used by Albert Einstein to explain the photoelectric effect
Density is an intensive property.
