Answer:
780 g
Explanation:
Step 1: Given data
Moles of sodium phosphate: 4.76 moles
Step 2: Calculate the mass corresponding to 4.76 moles of sodium phosphate
To convert moles to mass, we need a conversion factor. In this case, we will use the molar mass of sodium phosphate, which is 163.94 g/mol.
4.76 mol × 163.94 g/mol = 780 g
Answer:
Explanation:
Combustion can be defined as the burning of a compound in the presence of oxygen to produce carbon dioxide and water. Because it involves the release of heat (energy), it is referred to as an exothermic reaction.
Fuel is an <u>organic compound</u> and it's combustion will also go through the process above and also <u>releases heat (exothermic reaction)</u> into the atmosphere after burning. However, same can be said about forest fire also; as the forest is made up of plants (whose major <u>constituents are organic </u>also). The forest fire can also be termed as combustion because it burns in the presence of oxygen, <u>releasing heat (energy) into the atmosphere</u> (which also makes it an <u>exothermic reaction</u>).
