Organisms decay in a solution. Minerals dissolve and crystalize. Rock fragments squeeze together

Answer:

Minerals dissolve and crystalize.

Explanation:

The chemical sedimentary rocks form when the parent material weathers into a sediment. The sediment includes chemical inorganic minerals and partially or completely degraded organic matter that comes from the remains of plants and animals. The layers of sediments get compacted with overlying heat and pressure which leads to the formation of chemical sedimentary rocks.

How many moles of H2 are produced from 5.8 moles of NH3

vodomira [7]

Answer:

1. 8.7moles of H2

2. 2.25moles of O2

Explanation:

1. 2NH3 —> N2 + 3H2

From the equation,

2moles of NH3 produce 3 moles of H2.

Therefore, 5.8moles of NH3 will produce Xmol of H2 i.e

Xmol of H2 = (5.8x3)/2 = 8.7moles

2. C3H8 + 5O2 —> 3CO2 + 4H2O

From the equation,

5moles of O2 produced 4moles of H2O.

Therefore, Xmol of O2 will produce 1.8mol of H2O i.e

Xmol of O2 = (5x1.8)/4 = 2.25moles

What shape would a molecule of carbon tetrachloride have?

Elden [556K]

Answer:

Tetrahedral

Explanation:

For the repulsion of the free electron pair theory, the shape of a molecule will be to repel the bonds and the free electrons on the central atom. In a molecule of carbon tetrachloride, the central atom (C) has no free electrons, so, the shape that repels better the charge is tetrahedral, as shown below.
