Answer:
10.77%
Explanation:
Molar mass of Cu = mass deposited/number of moles of Cu
Molar mass of Cu = 0.4391 g/6.238x10^-3 moles
Molar mass of Cu = 70.391 g/mol
%error = 70.391 g/mol - 63.546 g/mol/63.546 g/mol × 100
%error = 10.77%
The answer is physical adaption.
Answer:
B) Transportation and photosynthesis
C) Cellular respiration and photosynthesis
Answer:
Fe + CuO ----> FeO+ Cu
Explanation:
A word equation is a chemical equation in which the reactants and products are represented by words rather than the respective symbols of the species involved in the reaction.
Generally, when writing a balanced reaction equation, it is normal to ensure that the number of atoms of each element on the reactant side is the same as the number of atoms of the same element on the product side. This has been ensured in the reaction above.
The reaction above is possible because iron is higher than copper in the electrochemical series hence iron can displace copper from its compounds.
