Answer:
<em><u>Rows in the periodic table are called periods</u></em>. As one moves from left to right in a given period, the chemical properties of the elements slowly change. <em><u>Columns in the periodic table are called groups</u></em>. Elements in a given group in the periodic table share many similar chemical and physical properties
Explanation:
Your hydrogen is being oxidized and your carbon dioxide is being reduced.
The mass of 1 atom of copper metal in the given face-centered cubic structure is determined as 1.054 x 10⁻²² g.
<h3>
Mass of 1 atom of copper</h3>
The mass of 1 atom of copper is calculated as follows;
mass of 1 atom of copper = molar mass of copper / Avogadro's number
substitute the value of molar mass of copper and Avogadro's number;
mass of 1 atom of copper = (63.5 g/mol) / (6.023 x 10²³)
mass of 1 atom of copper = 1.054 x 10⁻²² g
Thus, the mass of 1 atom of copper is determined as 1.054 x 10⁻²² g.
