It's always a square. 26/4= 6.5 :) There's your answer

STOICHIOMETRY
2Al + 3CuSO4 ! Al2(SO4)3 + 3Cu What is the maximum amount of Cu (63.5 g/mol) that could be produced by reacting 20.0 grams of Al (27.0 g/mol) with excess CuSO4?

Philosophy
Symbolize these arguments and display truth trees to evaluate the resulting argument forms for validity. If the argument form is invalid, describe (in English) the conditions under which the premises would be true but the conclusion false. 99.32 There will be scorpions in the ...

Prove informally, by employing correct definitions and principles of reasoning, that the following are true. 1/ Every formula implies itself. (That is, A implies A . Hint: For this one you will need to employ the definition of interpretation.) 2/ If set S implies formula A , t...

Physics
When will an object be in equilirium if different forces are acting on the object from the different systems? Would it be appropriate to use F=ma to find the equilibrium?

College Chemistry
what is the maximum weight of CuCl that can be prepared from the reaction sequence using 1.0g of Cu turnings to prepare the Cu2+ solution?

College Chemistry
how many grams of metallic copper are required to react with the number of moles of Cu2+ , 0.16mol, to form CuCl overall reaction can be taken as: Cu2+(aq) + 2 Cl- (aq) + Cu(s)-->2CuCl(s)

College Chemistry
The Cu2+ ions in this experiment are produced by the reaction of 1.0 g copper turnings with excess nitric acid. How many moles of Cu2+ are produced?
