Answer:
56.8 g
Explanation:
Your first conversion factor is the molar mass of H2O to convert from grams of water to moles. Your second conversion factor is the mole ratio of 2 mol C2H10 for every 10 mol H2O. Your last conversion factor is the molar mass of C2H10 to convert from moles back to grams.
150. g H2O • (1 mol H2O / 18.02 g H2O) • (2 mol C2H10 / 10 mol H2O) • (34.1 g C2H10 / 1 mol C2H10) = 56.8 g C2H10
Answer : The shape of the fluoroform molecule is Tetrahedral.
Explanation :
First we have to calculate the Hybridization of the molecule by formula,
where,
V = Number of valence shell electron in central atom
H = Number of neighboring monovalent atom
C = charge of cation
A = charge of anion
The central atom in this molecule is Carbon, it has 4 electrons in their valence shell.
The neighboring monovalent atoms are one Hydrogen atom and three Fluorine atom.
There is no charge of cation and anion on the given molecule.
V = 4
H = 1 Hydrogen atom + 3 fluorine atom = 4
C = 0
A = 0
By the above hybridization formula, we get
= 4
The number of electron pair = 4
The number of lone pair = 0
The number of electrons is 4, this means that the hybridization is and the geometry of the molecule is Tetrahedral.
The geometry of the molecule is shown below.
Answer:
the atom is neutral, the nucleus is positive
Explanation:
Answer:
It comes from older rocks,It forms from sediments,it is one of the main 3 rocks, con form from materials solidified from solution.
Explanation:
Most of the rocks exposed at the surface of Earth are sedimentary--formed from particles of older rocks that have been broken apart by water or wind. The gravel, sand, and mud settle to the bottom in rivers, lakes, and oceans.These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock.Sedimentary rocks are one of three main types of rocks, along with igneous and metamorphic. Dissolved minerals in the ground water precipitate (crystallize) from water in the pore spaces forming mineral crusts on the sedimentary grains, gradually cementing the sediments, thus forming a rock.
