Answer:
The answer to your question is 175 gallons
Explanation:
Data
60% antifreeze solution volume = ? = x
25% antifreeze solution volume = 25%
Final concentration 50%
Process
0.6x + 0.25(70) = 0.5(70 + x)
Simplification
0.6x + 17.5 = 35 + 0.5x
0.6x - 0.5x = 35 - 17.5
0.1x = 17.5
x = 17.5/0.1
Result
x = 175 gallons
The describes the reducing agent in the reaction below.
→
Reducing agent is the species in which oxidation is takes place. Reducing agent is the species in which loss of electrons is takes place. In the above reaction bromine ion in left hand side of the reaction loss electron to become bromine atom. So, bromine ion is reducing agent.
Oxidizing agent is the species in which reduction is takes place. Oxidizing agent is the species in which gain of electrons is takes place. In the above reaction chlorine atom in right hand side of the reaction gain electron to become chlorine ion. So, chlorine atom is reducing agent.

There are approximately 160 grams in 1 mol of Fe2O3 molecules. Therefore, there would be 79/160= 0.49375 mols of Fe2O3 molecules in 79 grams. There are 5 atoms in total for each molecule of Fe2O3, therefore 79/160 * 5 = 79/32 = 2.46875 mols of atoms.
Answer: False
Explanation: In the written form of an ionic compound, the positively charged cation always comes before the negatively charged anion. For instance, the written name for is calcium chloride because the compound has calcium () cations and chloride () anions.
