Answer: 17.34 grams of alum will be produced if 0.9875 g of Aluminium foil was used.
Explanation: Reaction to form alum from Aluminium is given as:
We are given Aluminium to be the limiting reactant, so the formation of alum will be dependent on Aluminium because it limits the formation of product.
By stoichiometry,
2 moles of Al is producing 2 moles of Alum
Mass of 2 moles of Aluminium = (2 × 27)g/mol = 54 g/mol
Mass of 2 moles of alum = (2 × 474)g/mol = 948 g/mol
54 g/mol of aluminium will produce 948 g/mol of alum, so
Amount of Alum produced = 17.34 grams
Theoretical yield of alum = 17.34 grams.
Answer: NaCl and H2O
Explanation: Products are on the right side of the arrow :)
Answer:
D
Explanation:
1.) First convert to molar mass
18.1*1/231.533*18.01528=
bacterial growth
Explanation:
Excessive bacterial growth is one of the example of a natural process that causes water pollution.
Pollution is the undesired concentration or harmful introduction of a particular body into the environment and causes harm overall.
- Pollution can result from both natural and anthropogenic sources.
- Anthropogenic causes of pollution are the most common due to activities of human beings.
- Natural causes of pollution results from the activities of nature in itself.
- From the given options, the bacterial growth is an natural process of pollution.

I took this quiz and the correct answer is not A.
4Na3PO4 The 4 at the beginning of the formula is important, it means you multiply everything after it by 4 so you would instead get the answer,
D. 12 Sodium, 4 phosphorus, 16 oxygen
